SINOMER® PETMP is a tetramercapto functional monomers. Because of the special reactivity of mercapto group, PETMP could be widely used as an adhesion promoter, an antioxygen cure inhibition agent, or a flexibility modifier in various free radical polymerization systems, such as UV curing. It also can be used as a low-temp. curing agent in epoxy curing system, as a high refractive index crosslinking agent in isocyanate crosslinking system.
