Nouryon Trigonox 239 Isopropylbenzene Hydrogen Peroxide 80-15-9

Trigonox 239
Isopropylbenzene Peroxide
CAS Number: 80-15-9
Physical Form: Liquid
Trigonox® 239 is an optimal curing system for hydrogen peroxide-cured isopropylbenzene:vinyl ester resins.
Applications
Trigonox® 239 is a peroxide mixture based on hydrogen peroxycumen. Trigonox® 239 was specifically developed for use in combination with cobalt accelerators to cure vinyl ester or styrene-acrylic resins. Trigonox® 239 can successfully replace commonly used ketone peroxides, such as Butanox LPT, and offers the following advantage: the peroxide does not “bleed” when mixed with pre-accelerated vinyl ester resins. This phenomenon is often considered a drawback of ketone peroxides in vinyl ester resins. Typically, no amine accelerator is required to achieve good curing, and rapid curing occurs in thin coatings and laminates no thicker than approximately 100. 6 mm, with low peak exothermic heat release in thick laminates.
