Two-component polyurethane various functions have been required in these coating applications. For example, the chemical resistance of coatings to cosmetics, sunscreens, and repellents has gained special attention in recent years. It is well known that certain chemicals in additives such as UV absorbers affect the quality of PU coatings. Conventional 2K PU coatings based on acrylic-urethane resins are not always sufficient to prevent the swelling or peeling caused by the chemical attack.
II. Material Name: Two-component polyurethane
We Two-component polyurethane material manufacturers are also adapting to the increasing digitization and automation of production processes. Sealing foams, adhesives, and casting compounds need to be processed more and more quickly today. The overall cycle times for handling, metering, and application are continuously optimized.
II. The Newest Improved Features of Two component polyurethane
Two component polyurethane including PU and Iso, are the processing of highly reactive materials that requires a high level of accuracy, reliability, and precision.
PU Gasket Foam Machine it has very strict requirements for the AB Two component polyurethane mixing system, PU (Polyurethane) and Iso (Isocyanate). It is the foam glue, the viscosity it is about Tens of thousands Mpas, generally 20000Mpas-60000Mpas of A, ratio 4:1, 5:1, 6:1, 7:1, with foam.
AB Adhesive Dispensing Machine, widely usage for the Two component polyurethane, ordinary viscosity it is about several thousand Mpas, AB mixing ratio generally 1:1, 2:1, no foam.
