Industry definitions
Backer: a phenolic sheet placed on the opposite (back) side of the substrate to which the laminate is
adhered. The backer is used to offset stresses on the substrate caused by the laminate. It also acts as a
moisture barrier (See Section 10.0).
No drip edge: a raised rim on a counter/benchtop/work surface to prevent runoff.
Glue line: the adhesive layer used to adhere laminate to the surface of a substrate.
J‑roller 3 inch: a handheld roller used to apply even pressure when bonding laminate to a surface. A
pressure of 50 pounds per lineal inch is recommended for most contact adhesives.

Off Fall: excess laminate due to dimensional inconsistencies or irregularities in the substrate to which
the laminate is applied.
Postforming: bending laminate sheet over or around the edge profile of a counter; this requires special
procedures (See Section 8.0)
Tempilaq
®
/Templistik
®
: colored marking chalk or wax that is heat‑sensitive, i.e., changes color or melts
when a certain temperature is reached; used to indicate that the surface of a laminate has reached the
proper temperature for thermoforming (325°F). (See Section 8.0)
Waterfall edge: a 90° postformed edge on a counter.

3M Static Dissipative Rigid Worksurface 8300 Series Specifications
Resistance values: Resistance measurements are used to establish the charge‑draining capability of the
static dissipative rigid worksurface. The ESD Association evaluates two resistance values in classifying
dissipative laminate and other static control surfacing materials. The tests are as follows:
1) Surface to Ground point resistance ‑ Use a 3M
™
Test Kit 701 for static control surfaces. Test the
resistance between the top surface of the table top and the ground point per ESD Association
Standard 4.1 [tested at 72°F (22°C), 50% RH]. The values should be between 1 x 10
6
‑ 1 x 10
9
ohms
(l ‑ 1,000 Megohms).
2) Point to Point resistance ‑ Use a 3M Test Kit 701 for static control surfaces. Test the resistance
between two points on the top surface of the table top per ESD Association Standard 4.1 [Tested at
72°F (22°C), 50% RH]. Typical value is 6 x 10
7
ohms (60 Megohms).
Additional Test:
Ground Point to Ground Point resistance – Perform this test when the worksurface ground connection
is to be electrically monitored. Equipment such as the 3M
™
Workstation Monitor 724 continuously
monitors the ground connection through the interior conductive layer of the laminate. Use a 3M™ Test
Kit 701 for static control surfaces to pretest and ensure that the grounding hardware is making sufficient
contact to the conductive layer. Connect one of the test leads to each of the two ground hardware items
installed on the tabletop. Set the test selector switch to the 10V position. Push the test button and the
reading should be less than 1 x 10
6
ohms (1 Megohm).

Dimensional changes: These changes are measured according to NEMA test methods. Samples are first
aged for 24 hours at 70°F (21°C) and 10% relative humidity. The same samples are then aged another
7 days at 100°F (38°C) and 100% RH. The gross change in dimensions (in both the machine and
cross‑machine directions) is measured after aging.
Machine direction: 1.1 % maximum change
Cross‑machine direction: 1.4% maximum change
E.
Use temperature range: ‑50°F (‑46°C) to 150°F (66°C)
NOTE: Continued use above 150°F will deteriorate the laminate. The controlling factor is the glue
line. The laminate itself could stand higher temperatures [up to 200°F (93°C)], but the potential
problems of shrinkage, adhesive failure, and substrate failure dictate lower use temperatures.
F.
Postformability: 0.5 in. (13 mm) minimum radius when parallel to the machine direction, 0.625 in.
(16 mm) minimum radius when perpendicular to the machine direction.

Packaging information
3M
™
Static Dissipative Rigid Worksurface 8300 Series is packaged according to 3M packaging standards.
The sheets are normally rolled and packed in vertical corrugated container with octagonal cross‑section. The
maximum number of sheets rolled up in a carton is determined by the weight of filled carton; the normal
number of sheets is five.

Shelf life
3M
™
Static Dissipative Rigid Worksurface 8300 Series does not deteriorate with time. However, laminate which
is to be postformed should be fabricated within one year of the date of manufacture. Laminate exposed to
extremely dry environments will shorten its shelf life. It is always good practice to rotate stock, using the oldest
material first.
6.0
Conditioning for fabrication
Preconditioning of laminate prior to fabrication is extremely important. The conditioning will affect
dimensional stability, formability, and the overall performance and handling of the laminate during fabrication.
Preconditioning is done to minimize dimensional changes due to the loss or gain of moisture. During the
process of making the papers used in laminate manufacture, the fibers are generally aligned in the machine
direction. Dimensional change is greater across the diameter of the fibers than along their length. As a result,
shrinkage is about twice as great in the cross direction as it is in the machine direction. An easy way to identify
the machine direction is to observe the sanding marks on the back of the laminate; these run in the machine
direction.

C.
Both the laminate and the substrate should be conditioned at approximately 75°F (24°C) and 45‑55%
RH for a minimum of 48 hours prior to fabrication.
Provision should be made to allow air circulation around the various components of the fabrication
process (i.e., laminate, substrate, etc.).
Where cracking may be a problem due to moisture differentials, the laminate should be thoroughly
dried out to minimize the rate of shrinkage. Fabricators have not experienced problems with buckling
or lifting of laminate when the laminate was dried prior to lamination and then later took on moisture.
(Note: Moisture in the laminate enhances its postforming properties.)
Decreasing the ambient humidity ‑ minimizes stress cracking
Increasing the ambient humidity ‑ facilitates postforming

Fabrication
3M
™
Rigid Worksurface 8300 Series is a rigid product and the top surface is very hard. Special tools and
procedures are required in order to fabricated this product successfully.
A.
Cutting/sawing/routing:
1. To avoid chipping during sawing, it is important that the rotation of the blade be such that the teeth of
the blade first contact and cut into the decorative (top) surface of the laminate. Therefore, with a hand
circular saw, the laminate should be cut with the decorative surface face down. With a table saw, the
decorative surface should face up.
2. Blades and bits used should be carbide‑tipped. A blade with more teeth will make a smoother cut.
Blades/bits should always be sharp. Recommended saw blades: triple chip grind, 10 – 15 degrees
positive rake. Ten inch diameter minimum 80 teeth, twelve inch diameter minimum 100 teeth.
3. The higher the rotation speed of the blade or bit, the cleaner the cut will be.
Caution:
Do not exceed manufacturers recommended rotation speeds.
4. The laminate should not be forced into a cutting blade, and it must be supported near the blade,
especially when cutting unmounted laminate.
5. When cutting openings into a finished benchtop covered with laminate, never cut the inside corners
of the opening at 90° (the point at which each such cut ends can serve as a source for a crack.)
Always round such inside corners to a minimum radius to 0.125 in. (3.2 mm). However, the largest
possible radius should be used.
6. After cutting/sawing/routing, the edges of the laminate should always be filed or sanded to remove
chips or nicks that may lead to a crack later on.
B.
C.
Sanding:
Sanding and filing should always be directed parallel to or away from the decorative surface.
Drilling:
Recommendations are generally the same as those for sawing. In addition, the material being drilled
should be backed to prevent breakout at the bottom of the hole.

A.
Postforming
The minimum radius around which 3M Rigid Worksurface 8300 should be formed is 0.50 in. when
parallel to the machine direction. If the laminate is post‑formed perpendicular to the machine direction
the minimum radius is 0.625 in.
Laminate sheets can be formed only in a straight line. They cannot be drawn over curved edges (e.g.,
covering a round tabletop) like vacuum‑formable plastic sheets can. The substrate must be clean,
smooth, and straight. Parallelism is essential in the moving parts of the forming operation.
In general, the laminate should be only slightly larger than the substrate [0.125‑0.25 in. (3.2‑6.4 mm)]
and should be trimmed after the forming operation is completed. Excessive overhang will tend to crack
or buckle during the postforming process. Check the edges of the laminate prior to forming. Any nicks
or cracks should be filed smooth before forming; if not, cracks can develop at these rough spots.
