Application of epoxy resins in consolidation of ornamental stone
Introduction
Although epoxy systems have been commercially available since the late 1940s, only in the last decade have they found widespread use as a means to consolidate and seal ornamental stone slabs. These systems are far simpler than those used in the paint industry, for example, in thin film applications, but they are nevertheless superior to polyester resins used for many years to consolidate marble slabs. Epoxies give better chemical, thermal and mechanical resistance as well as improved adhesive strength. Furthermore, it's possible to tailor the epoxy formula to enhance desirable characteristics. Even higher versatility is provided because two constituents are involved, and the final properties will be a contribution from both the resin and the curing agent.
