Vanishing Red is used by customers in the composites market as part of the curing process for unsaturated resins. Its red color gradually vanishes as resins cure, allowing customers to better monitor the dosing, mixing, and curing progress. Vanishing Red is especially useful for automated processes used to make products such as wind turbine blades and boats.
“Customers using automated dosing equipment may face problems if peroxide doesn’t properly flow through the dosing line, leading to under-cured or uncured end products,” said Raymond ten Broeke, Polymer Chemistry customer support engineer at Nouryon. “This can be very costly to manufacturers if molds need to be cleaned. Using Vanishing Red peroxides helps prevent such failures without leaving a trace that any indicator was used.”
