Question 1

What is ZEMSIL CS-602?

Accepted Answer

ZEMSIL CS-602 (3-Glycidoxypropyltrimethoxysilane (GPTMS), CAS 2530-83-8) is a ZEMSIL® silicone material. ZEMSIL CS-602 (3-glycidoxypropyltrimethoxysilane) is the most widely used epoxy-functional silane coupling agent, equivalent to KH-560 and A-187. The epoxide group reacts with epoxy resins, amines, and anhydrides while methoxy groups bond to glass, silica, and metal oxide surfaces. Essential for glass fiber sizing in epoxy composites, mineral filler surface treatment, and epoxy adhesive formulation.

Question 2

What is ZEMSIL CS-602 equivalent to?

Accepted Answer

ZEMSIL CS-602 is equivalent to KH-560, A-187, Dynasylan GLYMO and can be used as a direct drop-in replacement in most formulations.

Question 3

What are the main applications of ZEMSIL CS-602?

Accepted Answer

ZEMSIL CS-602 is used in: Epoxy adhesive adhesion promotion, Glass fiber sizing (epoxy composites), Mineral filler treatment for epoxy, Dental composites.
