What is the difference between thermosetting acrylic resin and thermoplastic acrylic resin?
The thermoplastic acrylic resin is a volatile substance which is volatilized and dried by a solvent; and the thermosetting acrylic resin is a crosslinked type paint which contains a functional group capable of crosslinking reaction, and is self-drying or cross-linked with other resins to finally complete the curing.
Detailed explanation of the nature:
The thermosetting acrylic resin is based on an acrylic monomer (methyl acrylate, ethyl acrylate, n-butyl acrylate and methyl methacrylate, n-butyl methacrylate, etc.), and is insoluble in a network structure. Melted acrylic polymer, in addition to the general properties of acrylic resin, heat resistance, water resistance, solvent resistance, abrasion resistance and scratch resistance; there are bulk casting materials, solution type, emulsion type, water type Form.
The thermoplastic acrylic resin means that the dried paint film is softened by heat, hardened by cooling, and the coating film is soluble; the main varieties are nitrocellulose lacquer, cellulose lacquer, self-drying acrylic lacquer and perchloroethylene lacquer; When there is usually a melting or softening temperature range, it can be plastically flowed under external force, and some properties are similar to natural resins; in order to facilitate processing and improve performance, additives are often added, and sometimes used directly for processing, so often Synonymous with plastic.
