Mercaptan-based hardeners

Mercaptan based hardeners offer a unique advantage of rapid cure with Bisphenol A epoxy resins for both at ambient and low temperatures, and even in thin film. Our polymercaptans are formulated to provide a wide selection of gel times ranging from 40 seconds to 60 minutes. As a pioneer supplier of mercaptans & mercaptan based hardeners in mainland China, we have more than half of the whole market share in rapid cure epoxy hardeners sector in China and approx. 80% of market share in silicon slices cutting glue for photovoltaic industries. 
Liquid mercaptan based hardener was first known for its rapid cure and low temperature cure proprieties in epoxy resin systems. Through years of continuous product & process improvement, our polymercaptan series are refined with reduced odor, excellent color, low toxicity and better adhesion to various different substrates.
