Application of Reactive Solid Acrylic Resin in Paint and Ink Industry

2022-04-15   Pageview:612

Acrylic resin has been widely used in coatings, inks, automotive industry, plexiglass, medical equipment and other fields since its birth in the last century. It is characterized by excellent weather resistance, high transparency and excellent mechanical properties. Today, most acrylic polymers are saturated resins; and acrylic resins with retained double bonds in their side chains have unique properties and application prospects, such as: resins that can be further polymerized into cross-linked resins, especially suitable for Applications for coatings, inks, viscose, plastics and elastomers. In addition, it can also be used to play a key role as a giant monomer in UV light curing formulations, that is to say, it can not only be used as a filler, but also can be cross-linked with other UV monomers or itself during the curing process, thereby enhancing the coating film. The effect of physical and chemical properties.

Reactive solid acrylic resins, including the following types of products:

Carboxylic acrylic resin, containing carboxyl group, can react with alkaline substances, mainly used as alkali-soluble resin, epoxy resin crosslinking agent,

Epoxy acrylic resin, containing epoxy groups, can undergo ring-opening addition with nucleophilic groups, and can be used for the preparation of powder coatings, additive for floor coating.

Hydroxy acrylic resins (acrylic polyols), containing hydroxyl groups, can react with various functional groups, and can be used in automotive refinishing paints; hot melt adhesives; metallic paints.

Unsaturated acrylic resin, the side chain contains unreacted double bonds, can continue to participate in polymerization as a macromonomer, mainly used in UV light curing.
