SUMILITERESIN® PR-T-10 IP is a novolac phenolic resin modified with bisphenol-A, which has good properties for foundry manufacture. It is designed with a low molecule number and low free phenol monomer in order to obtain high strength, low thermal expansion, and low gas volume. It is preferable to add about 15% hexamine/resin when applied in resin coated sand (RCS).Information provided by Sumitomo Bakelite High Performance Plastics (sbhpp) |
