- Any of various usually thermosetting resins capable of forming tight cross-linked polymer structures characterized by toughness, strong adhesion, and low shrinkage, used especially in surface coatings and adhesives.
- Containing an oxygen atom bound to two different atoms linked in some other way, especially a compound containing a ring formed by one oxygen atom and two carbon atoms.
- Any of various artificial resins made of chains of epoxide rings. Epoxies are tough, very adhesive, and resistant to chemicals. They are used to make protective coatings and glues. Also called epoxy resin
A high-strength adhesive, often made of two different materials that must be mixed together just prior to use.
