Description

Trigonox 93

Trigonox® 93 is a promoted tert-butyl peroxy ester for the cure of unsaturated polyester and vinylester resins.
Trigonox® 93 is based on an aromatic perester, alternatively Trigonox® 42PR can be used which is an aliphatic perester.

Application

Trigonox® 93 is a peroxide formulation based on tert-butylperoxybenzoate and acetylacetone. Trigonox® 93 has been developed for the cure of unsaturated polyester resins in combination with a cobalt accelerator (e.g. Accelerator NL-53N = 10% cobalt) in the temperature range of 60°C and higher. Trigonox® 93 plus a cobalt accelerator can effectively be used
as a match for Trigonox® 21S in those areas where the use of Trigonox® 21S is restricted by its official transport and storage temperature of max. 20°C. Application area for the cure system Trigonox® 93 plus a cobalt accelerator can be e.g. artificial marble, polymer concrete, filament winding and air drying lacquers. The combination Trigonox® 93 plus a cobalt
accelerator and possibly an amine accelerator like N,N-Dimethylaniline is also very suitable for the ambient temperature cure of vinylester resins. Trigonox® 93 gives in these resins a much faster cure than the commonly applied peroxides Butanox LPT-IN and Trigonox® 239.
