Amino Resin - Amino Resin

Japanese: アミノ樹脂 - アミノジュシ
Amino Resin - Amino Resin

A general term for thermosetting resins produced by the reaction of amine or amide compounds with aldehydes. Examples include urea resins, aniline-formaldehyde resins, melamine resins, guanamine resins, and thiourea resins. Formaldehyde is mainly used as the aldehyde. When an amino compound or amide compound reacts with formaldehyde, formaldehyde is added to the nitrogen atom to produce a methylol compound (hydroxymethyl compound). When a methylol compound is heated in the presence of an acid catalyst, it crosslinks and hardens. It is also used alone or mixed with alkyd resins to form aminoalkyd resins. It is used as a molding material, paint, adhesive, binder, etc., and aminoalkyd resins in particular can be heated and hardened at low temperatures in a short time. It is transparent and has good color fastness, and is excellent in terms of abrasion resistance, chemical resistance, and flame retardancy, so it is used as an embossed paint.
