| Peroxide mixture, specially developed for the production and cure of thick laminates and for applications where a high peak exotherm should be avoided. Applications such as pipes, tanks, windmill rotors. CAS number: 1338-23-4 EINECS/ELINCS No: 215-661-2 Applications: Trigonox 75 VRN is a methyl ethyl ketone peroxide formulation for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures. Trigonox 75 VRN offers all the advantages of standard Trigonox 75. The Trigonox 75 VRN includes a vanishing red indicator system that in most cases virtually disappears during cure. The red color is there when you need it i.e. during the mixing step, but will disappear during cure. In thin laminates up to approx. 4 mm Trigonox 75 VRN performs comparable with Butanox M-50, however, in thicker laminates up to approx. 10 mm Trigonox 75 VRN gives a reduced peak exotherm at equal gel time and curing time. Therefore, Trigonox 75 VRN is suitable for the cure of both thin and thick sections in one particular product. Information provided by Nouryon |
