appliance

Trigonox® 289-IN VR is a convenient initiator for curing unsaturated polyester, vinyl ester and acrylic thermoset resins with metal salts under ambient conditions. Trigonox® 289-IN VR offers the benefits of standard red peroxide formulations, indicating product flow and proper mixing with the resin. However, the Vanishing Red (VR) line of products includes a red color indication system that disappears during the curing process. The red color is visible only when needed, but not in the final product. The main features are: indication of the presence of the initiator, monitoring of the mixing step, monitoring of the cure by color and indication of uncured areas in the mold, and last but not least, it keeps the final product colorless after cure.
