epoxyAny of a class of thermosetting polymers, polyethers built up from monomers with an ether group that takes the form of a three-membered epoxide ring. The familiar two-part epoxy adhesives consist of a resin with epoxide rings at the ends of its molecules and a curing agent containing amines or anhydrides. When mixed, these react to yield, after curing, a complex network with ether groups linking the monomers. Stable, tough, and resistant to corrosive chemicals, epoxies are excellent adhesives and useful surface coatings. |

| The catalog describes a wide variety of maintenance products, including Devcon epoxy and urethane compounds for repairing rubber, metal and other surfaces. Related to the epoxy family, oxetane chemistry reportedly produces faster photocures, higher green strength, and better resistance to moisture for higher dimensional stability. The key to epoxy success is correct surface preparation and accurate mixing of hardener and resin; it's not a chemistry experiment. |
