Polyurethane reactive (PUR) adhesives are high-performance adhesives that combine the fast-cure characteristics of hot-melt systems with the long-term strength of reactive cures. Once cured, PUR adhesives provide excellent adhesion to a variety of substrates, including wood, plastics, metals, textiles, and composites. Key advantages include high bond strength, flexibility, resistance to heat, moisture, and chemicals, and long-term durability, making them widely used in woodworking, packaging lamination, automotive interiors, footwear, electronics, and construction.
Low molecular weight thermoplastic acrylic resin, as the core modifying component in PUR adhesives, exhibits low intrinsic viscosity and excellent processability. Low molecular weight thermoplastic acrylic resin enhances initial tack and prolongs open time, optimizing construction adaptability. It also improves adhesion to non-polar substrates such as PP/PE through tackification. SA-529 is an Low Viscosity thermoplastic acrylic solid resin primarily composed of a copolymer of methyl methacrylate and butyl methacrylate.
Product Description
Low molecular weight thermoplastic acrylic resin SA-529 boasts excellent dispersibility, low viscosity, good adhesion, and good alcohol solubility. As a key component of PUR adhesives, it significantly enhances their overall performance, improving initial tack, film formation, open time, and the dispersibility of additives in PUR adhesives. Low Viscosity acrylic resin SA-529 can also be used as a primary component in UV coatings, enhancing adhesion and substrate compatibility.
