Desco 66402 Statfree T2 Plus Dissipative Dual Layer Rubber Roll, Blue, 36" X 40' X .060"
Desco 66402 — Statfree T2 Plus Dissipative Dual Layer Rubber Roll, Blue, 36" × 40' × .060"
The Desco 66402 Statfree T2 Plus is a dissipative dual layer rubber roll for custom-cut ESD worksurface installations, workbench covering, and large-area EPA surfacing. The 36-inch width suits wide single-operator benches and shared two-person bench configurations. 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 66075. Made in the USA.

Key Features
- 36" Width for Wide Bench Configurations: 36-inch width covers standard wide production benches and shared two-person workstations. 40-foot roll allows cutting to any required bench length.
- 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 66075.
- RoHS Compliant. Made in USA.
Frequently Asked Questions
Is the Desco 66402 a direct replacement for the Desco 66075?
Yes. The Desco 66402 Statfree T2 Plus is the suggested replacement for the discontinued Desco 66075. It delivers equivalent dual layer dissipative/conductive rubber roll performance in the same 36" width with the improved nitrile rubber compound and UV stabilizers of the T2 Plus series.
How do I ground a T2 Plus rubber roll installation?
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 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. Cut edges do not affect ESD performance of the remaining material.
