Aminoplasts are thermosetting resins composed of an amine and an aldehyde. They are commonly used as adhesives, especially in the manufacturing of laminates, plywood, and particleboard. Aminoplasts are known for their high strength, outstanding water resistance, and excellent heat tolerance. Some synonyms for aminoplasts include amino resins, melamine formaldehyde, and urea formaldehyde. Amino resins are the general category for synthetic resins that contain amino groups, while melamine formaldehyde is a type of aminoplast that is made by polymerizing melamine with formaldehyde. Urea formaldehyde, on the other hand, is a type of aminoplast that is synthesized by the reaction of urea and formaldehyde.
