About KJ Chemicals

KJ Chemicals, founded in 2014, and headquartered in Tokyo, Japan, is a specialist in functional monomers and polymers. Focusing on unique synthesis technologies, it supplies advanced materials for coatings, adhesives, and electronics applications. For the coatings industry, KJ Chemicals offers specialty (meth)acrylate monomers and UV-curable resins. These deliver high reactivity, low shrinkage, excellent adhesion, and mechanical properties in radiation-curable, industrial, and specialty coatings systems.

Kohshylmer® DMAPAA™-MHQ (N-(3-(Dimethylamino)propyl)acrylamide)

Kohshylmer® DMAPAA™-MHQ (N-(3-(Dimethylamino)propyl)acrylamide) by KJ Chemicals is a cationic amide monomer. It possesses high hydrolysis resistance and much stronger base strength (Pka= 10.35) than DMAEA™ and dimethylaminoethyl methacrylate. It readily reacts with alkyl halide and with sulfuric ester to form quaternary ammonium salts.<br> <ul style="padding-left: 40px;"><li>Kohshylmer® DMAPAA™-MHQ (N-(3-(Dimethylamino)propyl)acrylamide) is recommended for dispersants, paints, coating materials and electrodeposition paints.</li> <li>It complies with ENCS (Japan), REACH (EU), EINECS (China) and TCSI (Taiwan).</li></ul>
