Grounding: This material must be properly grounded for optimum electrical performance. See Tech Bulletin TB-2000 for
mat grounding instructions.
Cleaning: For optimum electrical performance, surface must be cleaned regularly using an ESD mat cleaner. We suggest
using our Reztore Surface & Mat Cleaner. Do not use cleaners with silicone. Silicone buildup will create an insulative film
on the surface.
Description:
Desco’s Statfree
®
UC mat is a 2mm thick, 2-layer, dissipative rubber material. It is designed to
provide a path to ground and eliminate static charge generation when used as a worksurface
table mat, shelf liner, and cart liner. The surface resistance (1 x 10
6
to < 1 x 10
9
ohms Rtt) of the color top layer meets
ANSI/ESD S20.20 worksurface required limit and recommendation of ANSI/ESD S4.1 for contact with ESD susceptible
items. The conductive (< 1 x 10
5
Rtt) bottom black layer reduces the resistance to ground (Rtg) from the top of the surface
to the groundable point ground and allows the mats to be used with ESD continuous monitors. The Statfree
®
UC material is
manufactured without Silicone or DOP additives. Although clean room requirements vary, Statfree
®
UC material will mostly
likely meet the requirements for a class 100 or higher clean room. Ultraviolet (UV) additives stabilize color retention, insure ESD
performance over time and eliminate surface layer deterioration resulting in cracking when the product is flexed.

Matting materials have a tendency to shrink slightly
when first unrolled. In applications where length
is critical, allow the material to relax for at least
4 hours before cutting to size. Always trim with a
sharp knife or razor blade.
