Aminoplast is a term that is often used in the field of chemistry. This term refers to a group of thermosetting plastics that are made from the reaction between formaldehyde and an amino compound. Aminoplasts are widely used in the manufacture of various products such as adhesives, coatings, and laminates. In this article, we will explore the definition, meaning, and associations of aminoplast.
Definitions
Aminoplast is a type of thermosetting resin that is formed by the reaction between formaldehyde and an amino compound. This reaction results in the formation of a cross-linked polymer that is highly resistant to heat and chemicals.
According to the International Union of Pure and Applied Chemistry (IUPAC), aminoplasts are “polymers derived from the reaction of formaldehyde with amines or amides, which are used in the production of adhesives, coatings, and laminates.”
Origin
The term aminoplast was first used in the early 20th century to describe the thermosetting plastics that were being developed at the time. The first aminoplasts were made by reacting formaldehyde with urea, which resulted in the formation of a highly cross-linked polymer.
Over the years, the process of making aminoplasts has been refined, and new types of aminoplasts have been developed. Today, aminoplasts are widely used in the manufacture of various products, including laminates, coatings, and adhesives.
Meaning in different dictionaries
The meaning of aminoplast is similar across different dictionaries. The term is generally defined as a type of thermosetting resin that is formed by the reaction between formaldehyde and an amino compound.
According to the Merriam-Webster dictionary, aminoplast is “a thermosetting resin made by the reaction of formaldehyde with an amino compound.”
The Oxford English Dictionary defines aminoplast as “a type of thermosetting resin that is formed by the reaction of formaldehyde with an amino compound, used in the manufacture of adhesives, coatings, and laminates.”
Associations
Aminoplasts are associated with various industries, including the construction, automotive, and electronics industries. They are used in the manufacture of a wide range of products, including laminates, coatings, and adhesives.
Aminoplasts are known for their excellent heat and chemical resistance, which makes them ideal for use in high-temperature applications. They are also highly durable and have good electrical insulation properties.
