Desco 66429 Mat Kit, Statfree T2 Plus Rubber, Dissipative, Dark Blue, 24"X48"X.060"
Desco 66429 — Statfree T2 Plus Dissipative Dual Layer Rubber Mat Kit, Dark Blue, 24" × 48" × .060"
The Desco 66429 Statfree T2 Plus Mat Kit is a complete ESD worksurface solution for single-operator bench installations. It includes a 24" × 48" dissipative dual layer rubber mat in dark blue with grounding hardware — ready to install as a compliant ESD worksurface without sourcing accessories separately. 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. Meets ANSI/ESD S20.20 worksurface requirements. Made in the USA.

What Is an ESD Worksurface Mat Kit?
A mat kit bundles the T2 Plus rubber mat with the grounding hardware needed to put it into service immediately. The mat alone requires a separate grounding cord and common point ground; the kit eliminates the need to source these accessories separately, making it the fastest path to a compliant S20.20 worksurface installation. The purpose of an ESD worksurface is to limit static electricity generation and remove charge from conductive objects placed on the surface. A dissipative top layer (1×10⁶ to <1×10⁹ Ω) is the preferred choice for bench top use per ANSI/ESD S4.1, dissipating charge safely without risk of rapid discharge damage to sensitive devices.
Key Features
- Complete Kit: Mat and grounding hardware included — ready-to-install compliant ESD worksurface for a single operator bench.
- 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.
- RoHS Compliant. Made in USA.
Frequently Asked Questions
What is included in the Desco 66429 mat kit?
The 66429 includes the Statfree T2 Plus dual layer rubber mat (24" × 48" × .060") and grounding hardware. This allows the mat to be put into service as a compliant ESD worksurface without purchasing a separate grounding cord or common point ground accessory.
Why choose a dissipative mat over a conductive mat for bench use?
Dissipative worksurfaces (1×10⁶ to <1×10⁹ Ω) are the preferred choice for bench tops per ANSI/ESD S4.1 because they dissipate charge slowly enough to prevent damaging rapid discharge from ESD-sensitive devices. Conductive materials (<1×10⁶ Ω) remove charge faster but can cause damage if a sensitive device contacts the surface — they are typically used for floor mats (ANSI/ESD S7.1), not bench tops.
Does the T2 Plus mat need to be grounded to function?
Yes. The mat must be properly grounded using the included grounding hardware to dissipate ESD charges. Without grounding, the mat cannot remove accumulated charge from the worksurface or objects placed on it. Verify grounding with a surface resistance meter after installation.
