Application:

Diacetoneacrylamide (DAAM) is an important vinyl monomer. DAAM molecular structure has multi-functional gene, which easily generates copolymerization with other vinyl monomers, thus introduces ketone carbonyl from hydrotropic polymer; taking advantage of the lively chemical property of ketone carbonyl, the polymer can occur reactions such as: polymerization, cross-linking reaction, addition reaction, etc. DAAM is widely applied in coating, adhesive, epoxy resin curing agent, silver halide imaging material, electronic packaging material, thermosetting polymer photosensitive resin additive, textile additive and other fields. DAAM can be also added into co-polymer as polymer modification monomer, it is the modifier of various polymers.

In recent years, the water-based paint and adhesive taking acrylic ester as the basic raw material have important position for excellent environmental protection and favorable comprehensive performances. Diacetoneacrylamide has been widely applied. Diacetoneacrylamide has little toxicity, especially has great benefit to enhance the bonding property of the coating, As functional monomer, DAAM can introduce ketone carbonyl form acrylate emulsion copolymer chain. Adding a certain amount of adipyl in this emulsion, after the film formation, the polymer emulsion realize cross-linking at room temperature. After adding DAAM, the emulsion coating has greatly improved on water resistance and solvent resistance and other performances. and greatly improved the cross-linking performance of this polymer.

Obviously, takes diacetoneacrylamide as an important chemical product, and it will be highly praised by the customers.
