  1. Methacryloyloxy is a special methacrylic ester monomer with a reactive methylene group. It is suitable as comonomer for adhesives and coatings as well as copolymer for emulsion polymerisation.
  2. Methacryloyloxy the main properties are used in low VOC solvent-based coating resins to reduce their viscosity. Improves the elasticity and toughness of the coating and reduces the glass conversion temperature for excellent elasticity and corrosion resistance. React with commonly used crosslinkers, such as methamine (melamine) and isocyanate. Room temperature film, no isocyanate crosslinking, through the Michael reaction, the oleamine structure can be with aldehyde and laryn reaction. Methacryloyloxy the adhesion to the metal layer is enhanced by the molyfer and the action of the molyes and the metal from the Chemicalbook.
  3. Methacryloyloxy in humid environment, there is excellent adhesive capacity of acetyl acetate polymer pesticide intermediates high solid acrylic solution photocurable reaction monomer adhesive with polymer cosmetics polymer pharmaceutical intermediates self-cross-linked acrylic emulsion can replace N-hydroxymethyl acrylamide, diacetone acrylamide, HEMA, etc., better reaction control, better product performance.
