Epoxy resin systems formulated from epichlorohydrin and bisphenol A demonstrate strong adhesive performance, dimensional stability, chemical corrosion tolerance, and thermal resistance. These properties support their implementation in protective coatings, structural adhesives, fiber-reinforced composites, and casting formulations. The chlorohydrin rubber synthesized from epichlorohydrin constitutes a specialized elastomer exhibiting distinct performance advantages. This material maintains resistance to swelling in conventional oils and standard solvents, preserves flexibility at reduced temperatures without plasticizer modification, and demonstrates operational characteristics that may exceed the performance parameters of nitrile, polychloroprene, and butyl rubber materials in selected applications.
