SINOMER® PETMP is a tetrathiol functional monomer. Due to the special reactivity of the thiol group, PEMP can be widely used as an adhesion promoter, antioxidant cure inhibitor or flexibility modifier in various free radical polymerization systems (such as UV curing). It can also be used as a low temperature curing agent in epoxy curing systems and a high refractive index crosslinking agent in isocyanate crosslinking systems.
Features:
High purity, high refractive index, low odor, low color
Good adhesion to various metals, excellent flexibility
Fast curing, antioxidant inhibition, low shrinkage
Excellent low temperature curing
