Epoxy Resin
The modern laboratory benchtop material — a superb combination of features and benefits. Durable, extremely chemical- and stain-resistant, mechanically strong and easily cleaned.
Simmons casts worktops, 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 benchtop 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
Withstands concentrated acids, alkalis and solvents without staining or degradation.
Mechanically strong
Dense and rigid — needs no backing material and resists heavy daily use.
Easily cleaned
Non-porous and seamless; wipes down clean and resists bacterial harbourage.
Durable & homogeneous
Solid all the way through — it cannot delaminate and performs the same throughout its thickness.

Chemical resistance
Tested to BS EN 438-2:1991 (24-hour spot test). Unaffected by the majority of common laboratory reagents — including acetone, alcohols, and hydrochloric and sulphuric acids. A small number of aggressive reagents cause slight bleaching or surface attack (e.g. dichloromethane, hydrofluoric acid, fuming nitric acid). Full classified spot-test matrix available on request — ref. SIM-CR-24.
Five standard colours.
