Trigonox 42PR

tert-Butyl peroxy-3,5,5-trimethylhexanoate

CAS Number: 13122-18-4

Physical form: liquid

Trigonox® 42PR is a peroxide formulation for curing unsaturated polyester resins with Accelerator NL-51PN (6% Cobalt Solution) at 60°C and higher.


Trigonox® 42PR is a peroxide formulation based on tert-butyl peroxy-3,5,5-trimethylhexanoate Trigonox® 42PR has been developed for the curing of unsaturated polyester resins in combination with cobalt accelerators at temperatures of 60°C and higher. Trigonox® 42PR with a cobalt accelerator can be effectively used as a match for Trigonox® 21, the use of which is limited by its official shipping and storage temperature of up to +20°C. Application areas for the curing system Trigonox® 42PR with a cobalt accelerator (e.g. Accelerator NL-53N, 10% Cobalt) can be: Artificial polyester resins, Cobalt, Cobalt, Cobalt and Cobalt. ) can be used for applications such as: artificial marble, polymer concrete, fiber winding, air drying paints. The combination of Trigonox® 42PR with cobalt accelerators and possibly amine accelerators (e.g. Accelerator NL-63-100 (N,N-dimethylaniline)) is also well suited for ambient temperature curing of vinyl ester resins. Trigonox® 42PR cures much faster in these resins than the commonly used peroxides Butanox LPT and Trigonox® 239.
