Epoxy Resin
The modern laboratory worksurface material, a superb combination of features and benefits. Durable, extremely chemical- and stain-resistant, mechanically strong and easily cleaned.
Simmons casts worksurfaces, sinks and components in solid, homogeneous epoxy resin. Because the material is the same all the way through, components cannot delaminate and exhibit the same excellent chemical resistance across their entire thickness; there is no surface coating to wear away.
The result is a worksurface that stands up to aggressive reagents, mechanical wear, heat and moisture, while remaining easy to keep clean, which is why it is the standard choice for laboratory environments worldwide.
Built for the bench.
Chemical & stain resistant
Conforms to SEFA 3-2020, tested in 2026: 40 of the 49 reagents leave no effect or only a slight change in colour or gloss, among them acetone, ethanol and concentrated hydrochloric acid.
Mechanically strong
Dense and rigid, needs no backing material and resists heavy daily use.
Easily cleaned
Seamless, and rated excellent for ease of decontamination to BS 4247.
Durable & homogeneous
Solid all the way through: it cannot delaminate and performs the same throughout its thickness.

Surface burning tested to UL 723 at UL, Northbrook, Illinois, 15 September 2025, on 15 mm black material. Decontamination tested by IRAS to BS 4247 Part 1 Test A, certificate 227, 1992. Not for use with dry ice or liquid nitrogen.
Chemical resistance
24-hour spot test to SEFA 3-2020, 49 reagents, by SGS INTRON in March 2026: no detectable effect from 16 reagents, only a slight change in colour or gloss from 24 more, a clearly discernible change from eight, and one level 3 result, 96% sulphuric acid. The standard allows four level 3 results, so the material conforms. All 49 results.
