What is Acrylic Resins?
Acrylic resins are polymeric materials that contain acrylic monomers. These monomers are esters of acrylate, methacrylate or their derivatives. Acrylic resins are copolymers, which can contain other monomers in the polymer chain to obtain a final product with different properties. A wide variety of monomers can be selected to enhance properties, such as weather resistance, moisture resistance, oxygen permeability, flexibility, and hardness depending on the focus to be taken.
Acrylic resin consists of thermoplastic and thermosetting types. Thermoplastic acrylic resin (thermoplastic acrylic resin) is an acrylic polymer material that can be flexible or formed at certain high temperatures and hardens again when cooling. Most types of thermoplastic have a high molecular weight.
Thermoplastic acrylic resins typically use methyl methacrylate in their polymer main chains to provide excellent exterior hardness and durability. In thermoplastic acrylic resins, the polymers that make up the resin do not contain reactive groups, so in these resins, the polymer chains are not cross-linked. In order to enhance the interaction between different polymer chains, polymers used are generally high molecular weight polymers. Therefore, these resins are usually water resistant, have excellent non-yellowing and gloss resistance, dry quickly, and have good adhesion. The main applications of these resins include paints, inks, and adhesives.
