Profile: IGC Technologies, Inc. specializes in manufacturing foundry products. Veinseal® is a patented sand core-additive which is a unique blend of quality materials engineered to prevent veining and gas defects in iron castings caused by thermal expansion of chemically bonded core sands. E-Shield™ water-based ceramic blends and E-Cast™ zircon coating can greatly improve the casting surface finish. Our formulations are designed to yield maximum protection at the core/metal interface by eliminating unsightly blemish defects. Mastertop™ is designed to supply an insulating and exothermic blanket covering molten metal, thus preventing heat loss. This protection assures the proper formation of piping by allowing the complete and total feeding of the castings. We are an ISO 9001 certified company.
