The two-component polyurethane adhesive is the product with the most varieties, the largest amount and the widest use among polyurethane adhesives. It can be used for bonding metal, rubber, plastic, fabric, leather, wood, ceramics, glass, etc. Even for plastics that are difficult to stick, such as polyethylene and polypropylene, it also has a certain bonding strength. The two-component polyurethane adhesive is mainly used for bonding soft materials or hard materials such as metals and plastics, impact vibration resistance or low temperature occasions. It is widely used in ships, machinery, automobiles, furniture, loudspeakers, tapes, electrical appliances, instrument watches, shoemaking, packaging, sports goods and other industries. In recent years, it is especially used for the bonding of automobile FRP parts and metals, such as SMC body panel, trunk lid, top cover, mudguard, side guard strip, windshield buffer, etc. It can also be used to repair cracks in the aircraft deck.

The polyurethane adhesive produced by our company is a special adhesive for laminating various films, aluminum foils and aluminized plastic films. Our products have good leveling property, strong soft cutting property and affinity, and high peel strength after bonding. They can bond film materials with different properties, such as propylene film, polyester film, polyamide film, aluminum foil, aluminized plastic film, etc. together through the laminating composite process to obtain cold resistance, oil resistance, drug resistance, transparency Composite films for flexible packaging with properties such as cooking resistance are used as packaging bags for cooking resistant and sterilized soft cans, food bags (such as pickle bags, biscuit bags, various small packaged brine meat snack bags, etc.), and packaging bags for medical appliances, drugs, pesticides, etc.

RJ8715/8715B is a two-component solvent based polyurethane adhesive for aluminum plastic composite used in flexible packaging. This product is suitable for AL (aluminum foil), PET (polyester film), PA (nylon film), BOPP (double pull polypropylene film), RCPP (high temperature resistant polypropylene film), kraft paper and other dry composite structures.

RJ8715/8715B has good affinity, strong initial viscosity of composite substrate, high peel strength of various composite structures, and good aging resistance. RJ8715/8715B is also particularly suitable for aluminum/plastic 100 ℃/30min boiling and plastic 100 ℃/30min boiling.
