ACRYLATE OLIGOMERS IN ULTRAVIOLET CURED PSA

WebHigher molecular weight urethane acrylate oligomers require some amount of acrylate monomer (usually 30% minimum) for thorough cure due to restricted molecular mobility. Urethane acrylate oligomers do not require any volatile solvents to reduce viscosity. Instead acrylate monomers are used as reactive diluents. WebAcrylonitrile–styrene–acrylate (ASA) is a terpolymer that can be produced by either a reaction process of all three monomers or by a graft process. The CAS number is 26299-47-8. ASA is usually made by introducing a grafted acrylic ester elastomer during the copolymerization of styrene and acrylonitrile, known as SAN. WebStearyl acrylate Octadecyl acrylate CAS No. 4813-57-4 Formula Application STA is used for textile coatings because of its high hydrophobicity. STA is used for adhesives resin because of its low polarity with high Tg. And it is also used for seed coatings because of its temperature dependability of gas permeability.
