Desco 66408 Statfree T2 Plus Dissipative Dual Layer Rubber Roll, Dark Grey, 24" X 40' X .060"
Desco 66408 — Statfree T2 Plus Dissipative Dual Layer Rubber Roll, Dark Grey, 24" × 40' × .060"
The Desco 66408 Statfree T2 Plus is a dissipative dual layer rubber roll for custom-cut ESD worksurface installations, workbench covering, and large-area EPA surfacing. The roll format allows the material to be cut to any required workstation length, making it ideal for covering long assembly benches, production lines, and custom-dimensioned ESD work areas. The two-layer construction delivers a dissipative top surface for safe contact with ESD-sensitive devices and a conductive bottom layer for grounding and ESD monitor compatibility. Replaces the discontinued Desco 66080 / D-66080.

Key Features
- Roll Format for Custom Installations: 40-foot roll allows cutting to any required bench length — ideal for long production benches, assembly lines, and custom EPA worksurface configurations.
- Dissipative Top Layer: Meets ANSI/ESD S20.20 worksurface required limits and ANSI/ESD S4.1 recommendations. Does not generate static charge; controls discharge rate from ESD-sensitive devices on the surface.
- Conductive Bottom Layer: Low-resistance path to ground enables use with ESD workstation continuous monitors and reduces Rtg from top surface to grounding point.
- Nitrile Rubber Oil-Resistant Compound: Resists oil absorption, maintaining electrical and physical properties through service life. Suitable for solder workstations with flux and chemicals.
- UV Stabilizer Additives: Preserves color retention and ESD performance; prevents surface cracking and deterioration over time.
- Laser Engraved Identification: ESD protective symbol, specifications, and manufacturer information on the bottom layer for product identification and EPA auditing.
- Replaces Desco 66080 / D-66080.
- RoHS Compliant. Made in USA.
Frequently Asked Questions
Is the Desco 66408 a direct replacement for the Desco 66080?
Yes. The Desco 66408 Statfree T2 Plus is the suggested replacement for the discontinued Desco 66080 and D-66080. It provides equivalent dual layer dissipative/conductive rubber roll performance with the improved nitrile rubber compound and UV stabilizers of the T2 Plus series.
How do I ground a T2 Plus rubber roll installation?
The T2 Plus roll must be grounded to dissipate ESD charges. Connect a mat grounding cord from the groundable snap or conductive bottom layer to a common point ground at the workstation. For long bench runs, use multiple grounding points spaced no more than the mat width apart to ensure consistent Rtg across the full surface. Verify grounding with a surface resistance meter after installation.
Can the T2 Plus roll be cut to a custom length?
Yes. The roll format is designed for cutting to any required bench length with standard utility or mat cutting tools. The 40-foot roll length accommodates most production bench configurations. Cut edges do not affect ESD performance of the remaining material.
What is the difference between the T2 Plus roll and a T2 Plus cut mat?
The T2 Plus roll (66408 and similar) provides the same dual layer rubber material in a 40-foot continuous roll for custom-cut bench installations. T2 Plus cut mats are pre-cut to specific dimensions with finished edges and are ready to place on a workstation without cutting. Choose the roll format for long benches or non-standard dimensions; choose a pre-cut mat for standard single-station use.
