Thermoset (n): Also called “thermosetting plastics” It is a material which hardens or sets when heat is applied and which, once set, cannot be resoftened by heating. The application of heat is called "curing " CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

Epoxy resin (n): Used in very strong adhesives. e.g. Epoxy resins are used for coatings, adhesives and foam. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

Cure (v): a process whereby a material is caused to form permanent molecular linkages by exposure to chemicals, heat, pressure and/or weathering e.g. During cooling or mixing, a chemical reaction occurs, causing thermosets to cure. This means they set permanently and cannot be molded again. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT
