CAS Number 1338-23-4; 80-15-9

Trigonox® 289-IN VRN is a special peroxide blend with a VR system, suitable for curing unsaturated polyester and vinylester resins at ambient conditions in conjunction with a metal accelerator.

Chemical Family Organic peroxide

Physical Form Liquid

Brand Trigonox®

Trigonox® 289-IN VRN is a convenient initiator suitable for curing unsaturated polyester, vinyl ester and acrylic thermosetting resins at ambient conditions in conjunction with a metal salt. Trigonox® 289-IN VRN offers the advantages of a standard red peroxide formulation to indicate product flow and proper mixing into the resin. The vanishing red (VR) series of products however include a red indicator system that disappears during the cure. The red color is only visible when needed but not in the finished end product. The key features are: indicates initiator presence, monitoring of the mixing step, monitoring of the cure by color and indicating under-cured area's in the mold, and last but not least it leaves the end product colorless after the cure.
