There are two kinds of epoxies, aliphatic, and aromatic. The aliphatic are very good in water. Epoxy is used as a water barrier on Polyester(fiberglass) boats to eliminate blistering. read more

Epoxy adhesives adhere to a wide variety of materials, and their properties are dependent upon the specific chemistry of the system and the nature of the cross-linking available. Some of the most important performance requirements include exceptional chemical and heat resistance, excellent adhesion and water resistance as well as satisfactory mechanical and electrical insulating properties. read more

One component epoxy adhesives are generally cured at temperatures between 250-300°F, conditions that engineer a product of high strength, excellent adhesion to metals, and outstanding environmental and harsh chemical resistance. read more
