Description
A thermosetting Amino resin that is made by reacting melamine with Formaldehyde. First made in 1933 by CIBA, melamine formaldehyde resins were most often used for molded plastic products and were filled with Cellulose, Wood flour, or mineral powders. They produce a hard, high gloss plastic that was used for utensils, containers, dishware (Melmac) and countertops (Formica®). Melamine formaldehyde resins are also used for Plywood, textile sizing, leather processing, and paper strengthening. They are resistant to water and biodegradation.
