Definition

Noun: A type of thermosetting synthetic resin produced by the condensation of amino compounds (such as urea or melamine) with aldehydes (like formaldehyde). It is characterized by its hardness, clarity, and resistance to heat and solvents. Aminoplasts are primarily used in molding materials, adhesives, and as coatings to provide a durable, protective layer.

Usage

Aminoplasts are industrial materials. The term is used in technical, manufacturing, and chemical contexts to describe the resin itself or products made from it. - As a material: "The tabletop is coated with a layer of aminoplast for durability." - As a category: "Urea-formaldehyde is a common type of aminoplast."

Examples

• The laboratory equipment was molded from a high-strength aminoplast.
• Aminoplast resins are key components in the production of laminated countertops.
• This adhesive is formulated with an aminoplast for superior water resistance.

Advanced Usage

• Technical Specification: In product data sheets, "aminoplast" specifies the resin chemistry, e.g., "The binder is a melamine-based aminoplast."
• Comparative Property: Used to discuss material properties, e.g., "Compared to phenolic resins, aminoplasts offer better color stability."

Variants and Related Words

• Amino Resin: A more general synonym for aminoplast.
• Urea-Formaldehyde (UF) Resin: A very common and specific type of aminoplast.
• Melamine-Formaldehyde (MF) Resin: Another major type of aminoplast, known for greater heat and moisture resistance.

Synonyms

• Amino resin
• Thermosetting amino resin

Related Phrases / Compounds

• Aminoplast molding compound: A ready-to-mold material containing the resin, filler, and other additives.
• Aminoplast coating: A protective surface layer made from this resin.

Noun

1. a plastic (synthetic resin) made from amino compounds; used as an adhesive and as a coating for paper and textiles
