1、 Features and main uses:

Tianrun TR-501-T70 is an unsaturated polyester resin (modified) synthesized from phthalic anhydride as the main raw material, which has been dissolved in styrene and added with an accelerator. It has the characteristics of good and fast infiltration of glass fiber, low heat release, fast curing, and good defoaming performance. The product has good transparency, low shrinkage, and good toughness. This resin is recommended for vacuum induction or vacuum assisted RTM processes, especially suitable for automotive components, cabin covers, transparent carbon fiber products, etc. There are many gel time options.
