your adhesive supplier for specific application requirements.
Micastat®is a universal grade laminate for use in general
purpose, postforming and high wear applications.For details
on the installation of Micastat®and other high pressure
laminated plastic sheets refer to National Electrical
Manufacturers Association (NEMA) publication LD 3-1995
or follow these step by step directions for non-postforming
applications.
1. Prepare the face of the substrate. It should be clean, dry
and free of all contaminants which would interfere with
adhesion. Caution should be taken when removing
sheets and pads from its box, sheets and pads are high
pressure laminate plastic and can be susceptible to
cracks and breaking if not conditioned before handling
and installation at 70 to 75deg F and 45-50% RH for 48
hours.
2. Stir the adhesive thoroughly and apply an even coat of
adhesive by either spray, roller or brush to both the
substrate face and the Micastat®back. Do not allow
coated surfaces to touch. Allow the cement to dry. When
bonding to plywood, apply a second coat if the first coat
completely penetrates the wood. Use uncoated wood
strips to assist in connecting coated surfaces.
3. Place thin, uncoated, wooden strips 12 inches apart
across the substrate face. This will keep coated surfaces
apart; bonding will occur once contact is made.
4. Position the over-cut Micastat®sheet on top of the
wooden strips.

Description
Micastat®is a high pressure static dissipative laminate
designed for workbench tops used in the manufacture and
assembly of ESD susceptible electronic components.
Micastat®meets ANSI/ESD S20.20 requiring RTG <109
Ohms per ESD S4.1 and antistatic low tribocharging
materials <200 volts per ESD STM 4.2. Its patented* multi-
layer construction features a conductive layer which
ensures dissipative properties independent of ambient
humidity. Micastat®shows superior abrasion resistance and
provides rapid, non-sparking charge dissipation. It can be
laminated to plywood, fiber board, partical board tables and
bench tops with conventional contact adhesives. It is
resistant to most solvents and greatly exceeds the NEMA
specification for wear resistance.
Figure 2. Micastat®layered construction
Installation
Micastat®is designed to be laminated to wooden tables or
bench tops with conventional contact adhesive and will
perform very well in the most rigorous postforming
applications to a minimum of 5/8" radius. Desco suggests
the use of a high quality solvent or water-based contact

5. Slowly remove strips of wood taking care to keep the
Micastat®in position. The Micastat®should fall into
position.
6. Push the laminate down with even hand pressure.
7. If the Micastat®falls out of position, squirt solvent (Desco
recommends the use of ST102 solvent from Pionite)
between the two surfaces and gently lift the Micastat®
sheet up. Wait a minimum of 4 hours before reapplying
another coat of adhesive, solvent must evaporate totally.
Apply another coat of adhesive to both surfaces and
reposition.
8. When Micastat®is in the correct position, seal the bond
with a rubber “J” roller or a carpeted block and rubber
mallet. Use either roller or block and mallet in a pattern
that forces any air bubbles out from underneath
laminate. If Micastat®sheet is oversized, sheet can now
be trimmed with a router. After trimming, edges should
be filed for a smooth splinter free edge.
Figure 4. Wooden block and rubber mallet and “J” roller
technique.
Once installed, Micastat®must be grounded to ensure
proper charge dissipation. Refer to general grounding
guidelines on this page.
Postforming Application
When the universal grade Micastat®is exposed to a
temperature of 325 degrees Fahrenheit it will soften
momentarily, allowing a straight line bend to be made. This
bend should be made quickly and uniformly and have a
radius equal to or greater than 5/8". The chemical change
that takes place in this process cannot be reversed;
Micastat®cannot be reheated. Proper postforming
machinery and close attention to details such as time and
temperature are essential for best results. Preinstallation
storage conditions are critical to postforming performance.
For detailed postforming information please refer to
NEMA publication LD 3-1995 or follow these general
directions.
1. Micastat®should be conditioned at 70°F to 75°F and 45-
50 percent relative humidity for 48 hours prior to
postforming. Recommended postforming machinery
includes Midwest Automation and Evans Rototorque.
2. The radiused edge of substrate must be smooth,
rounded, and free of irregularities and loose particles.
3. Lead-in cracks may be minimized by ensuring a smooth
cut on the edge of the laminate.
4. Always bond Micastat®to a suitable substrate such as
medium to high density fiberboard, or particleboard. It
should not be glued directly to plaster walls, gypsum
wallboard, concrete, or metals.
5. Recommended adhesives include solvent or water-
based contact cement, white glue (PVA), epoxy, and hot
melt glue. Consult your adhesive supplier for specific
application requirements.
6. The use of a backing sheet is recommended to minimize
warpage. The thickness of the backing sheet should be
relatively equal to the thickness of the decorative
laminate on the face of the assembly.
7. The decorative surface to be formed should be heated to
a temperature of 325°F to 375°F (165°C to 190°C).
8. Heat the Micastat®“wings” only, to 325°F to 375°F
(165°C to 190°C) with a Chomelux heater held 2" to 2.5"
from the surface. Tempilaq®liquid temperature indicator
or equivalent should be used to determine the
temperature.
9. The desired heat-up rate of 325°F (165°C) should be
one second for every 0.001" of thickness (i.e., 30
seconds for .028", 38 seconds for .038".
10. Forming should be accomplished within 5 seconds of
achieving proper surface temperature.
11. Heat up rates of laminate are affected by thickness,
color, and finish. Temperatures should be verified by
temperature-indicating wax (Tempilaq®).
12. Let the Micastat®laminate cool for five to ten minutes
under pressure.
Fabrication Tips
1. All saw blades and router bits used for cutting should be
carbide tipped. Feed rate should be slow and tool speed
should be high. To minimize the development of surface
scratches caused by router bits, lubricating the laminate
edge with a wax stick is recommended prior to tooling.

2. Inside corners of cutouts for electrical outlets, sinks, etc.,
should have a minimum radius of 1/8" (3mm) and should
be filed smooth. This reduces the likelihood of stress
cracks.
3. All edges of laminate should be filed smooth with file
direction towards substrate to help prevent stress cracks
and to minimize chipping.
4. When nails or screws must be used, it is advisable to first
drill an oversized hole through the laminate. This
reduces the likelihood of stress cracks.
5. Micastat®is intended for interior use only, and should not
be exposed to extreme humidity, continuous sunlight, or
temperatures above 275°F (135°C) for extended periods
of time.
6. Work surfaces must be grounded for proper static
dissipation.

Once installed, Micastat®must be grounded to ensure
proper charge dissipation. See below.
General Grounding Guidelines
1. When grounding Micastat®, it is essential to make
intimate contact with the conductive layer which is
directly below the dissipative, color layer. See the
diagram on page 1 showing the multi-layered
construction.
2. For proper and safe ESD protection, the grounding wire
must be tied directly to and at the same potential as the
facility power ground or “green wire” ground. A typical
“green wire” ground if properly wired is the screw of a
switch or outlet cover plate.
3. If power is to be used at the ESD protected workstation,
per ANSI/ESD S20.20 paragraph 5, a Ground Fault
Circuit Interrupter (GFCI) is recommended.
4. Test all workstation grounds for proper resistance to
ground. See Desco Technical Bulletin TB-2007 for a
complete discussion of grounds. For information on
instruments and procedures for the proper testing of
grounds we recommend that you contact ECOS
Electronics, 205 Harrison Street, Oak Park, IL 60304,
(708) 383-2505, Fax (708) 383-2137.
Figure 5. Outlet plate with “green wire” ground
5. The selection of ground cords is intimately related to the
organization’s material handling procedures. It is
important for a user to be familiar with his/her own
organization’s grounding specifications and ESD
procedures prior to selecting ground cords. See
paragraph 2 in Cautions section of this Technical Bulletin.

14246.
Installing the Flush Mount Insert
Ground System
The following instructions are based on a top with a
thickness of 1-1/4" (30mm) tops.
2.1. Using drill tool 14242:
Figure 8. Drill Tool 14242.
a. Set the 1/4" (6mm) drill bit and adjustable
counterbore so that the 1/4" (6mm) bit will drill
clear through the work surface.
b. Set the drill stop so the drilling depth of the 1/2"
(12mm) counterbore is .200" (+.000" - .010")
2.2. Using the drill kit 14242 as adjusted above, position
drill bit on the top of the worksurface at the point you
want to install the flush mount insert.
2.3. Drill perpendicular from the top surface straight into
the work surface until the drill stop touches the
laminate surface. This should be at a depth of .200".
2.4. Using the 1/4" (6mm) pilot hole on the bottom of the
work surface drill a 1 1/2" (37mm) diameter
counterbore 5/8" (16mm) deep, of no more than 1/2
the thickness of the worksurface.
2.5. Seat the 8-32 cap screw through the brass insert so
that it sits flat with the top of the insert.
2.6. Push the cap screw and brass insert assembly into
the 1/2" (12mm) diameter hole on top of the
worksurface. Attach and tighten the 8-32 nut until the
brass insert is flush with the laminate surface.
2.7. Remove the 8-32 nut and install the flat washer, ring
terminal and 8-32 nut as shown above. The ring
terminal is for a ground wire attachment.
2.8. Using approximately 22 gauge wire, crimp the
supplied ring terminal to the wire and secure it to the
8-32 cap screw using the 8-32 nut. Attach the
unterminated wire end to a building ground. THE
MICASTAT®WORKSURFACE IS NOW GROUNDED.
Recommended practice per ANSI/EOS/ESD S6.1-
1991 is no resistor between the common point ground
terminal and a worksurface, floor mat, or shelving.
2.9. FOR INSTALLING dual wrist strap ground (item
09740) included with item 14246 ONLY. Place item
09740 at the position desired to install, screw in place
using enclosed screws.
2.10. Using the ground wire from the 09740, cut the length
of the ground cord so that it will reach from the 09740
to the underside of the worksurface at the 8-32 screw.
Crimp the extra ring terminal to the end of the wire
and bolt it to the underside of the work surface using
the 8-32 cap screw and nut.
2.11. Using the remaining wire cut from the 09740, attach
the ring terminal end to the 8-32 cap screw and nut.
Using the ring terminal enclosed, terminate the other
end to a ground source. This will GROUND both the
Micastat®top and the dual wrist strap ground.
Grounding Method for Continuous Monitors
Materials Needed for Item 19232 and 19665:
2 ea. 14244 Flush Mount Laminate Ground Insert
1 ea. 14242 Installation Tool for Flush Mount Insert
1. Install the Flush Mount Inserts first. It is recommended to
install one in the right back corner and the other in the
left back corner of the Micastat®laminated bench top.
2. Once both inserts are installed, cut the ground cord
supplied with the monitor into two pieces; make sure that
the tinned end is long enough to connect from the
monitor to one of the flush mount terminals located under
the bench.
3. The remaining wire can then be used to connect the
other flush mount terminal to ground using the supplied
ring terminal. The shrouded molded end can then be cut
off.
When complete, one flush mount terminal will connect the
Micastat®laminate to ground, while the other will connect it
to a monitor. The monitor then monitors the ground
connection between the two inserts, and since Micastat® is

1 ea. 14242 Installation Tool for Flush Mount Insert
1 ea. 09857 10mm Socket and Rivet (100 per pack)
2 ea. 8-32 button cap screws
1. Install the 14244 Flush Mount Inserts in the snap pattern
for the monitor.
2. Once installed, remove the 8-32 taper head screw
supplied.
3. Place a 10mm snap socket on top of the installed 14244
brass insert.
4. Screw the 10mm snap socket into place on the insert
using an 8-32 button cap screw.
5. Do this for both inserts and snap attach the 19212 Mini
Monitor into place; it is now grounded to and monitoring
the Micastat®.
Grounding Method for Micastat®Pads
Micastat®Pads have the same dissipative characteristics as
Micastat®Sheet. The pads have pressure sensitive
adhesive on the underside for rapid and secure installation.
They are packed complete with an installed, 10mm (.395")
snap socket and a Common Point Ground Cord Item No.
09826. The Common Point Ground provides banana jack
receptacles for two wrist straps.
Figure 9. Proper installation of Micastat®Pad.
1. Remove the protective carrier from the pressure
sensitive adhesive. Lay the Micastat®Pad in position and
snap on the 09826 ground cord. Bring the other end of
the ground cord to a “green earth ground” and attach it
using the ring terminal. A suggested “green earth ground”
is the center screw of a standard outlet. Testing is
recommended to ensure that the screw is properly
grounded. If there is excess wire you may want to cut
and strip the ground wire to a shorter length and attach it
with another ring terminal, which is included with each
09826 ground cord.
Cautions
1. Only one (1) groundable point should exist on any ESD
protective work surface or floormat. ESD protective
workstation components, such as work surfaces, should
never be grounded in series (daisy chained).
Figure 10. Work surfaces should NEVER be daisy chained.
2. The Common Point Ground Cord shipped with the
Micastat®Pad has a 1 Megohm resistor. A non-resistor
Common Point Ground Cord, Item No. 09825 may be
purchased separately.
3. The ESD-S1-1 Standard calls for a 1 megohm current
limiting resistor in the wrist straps used with an ESD
protective work surface such as Micastat®Pads or
Sheets.
4. ESD Handbook TR20.20 worksurface 5.3.1.9.3 High
Pressure Laminates. These materials are rigid and are
applied to a substrate, typically with adhesive systems.
The majority of these materials follow the multi-layer
description above. There are, however, some types that
are basically homogeneous in construction.
Because the electrical properties of many high pressure
laminates have some degree of humidity dependence, all
high pressure laminate materials should be carefully
tested for adequate performance at low humidity prior to
selection and installation.
Multi-layer Micastat® with conductive layer is not
homogenous and is not humidity dependent.
Testing
There are two types of tests for monitoring Micastat®
surface electrical characteristics. One type of test is RTG -
Resistance To Ground (see Figure 12). In this test you
measure the resistance of the laminate surface to the
installed ground bolt (or snap on a Micastat®Pad). When

Maintenance
1. It is important to store Micastat®laminate sheets at the
same relative humidity as the material to which it will be
bonded. This will prevent a moisture imbalance in
application.
2. Micastat®may swell slightly if a damp object is kept in
continuous contact with the surface for more than 12
hours. This is normal; the swelling will disappear soon
after the damp object is removed.
3. Micastat®may be cleaned with Reztore®Antistatic
Surface and Mat Cleaner, Item No. 10435 or any
household soap solution. Be careful that household
soaps are silicone free and do not leave an insulative
layer behind. This will reduce electrical properties.
Difficult stains may be removed with organic solvents
such as acetone, alcohol, methyl ethyl ketone (MEK) or
paint thinner.
