Crosslinking methods of waterborne polyurethane and commonly used crosslinking agents
What is crosslinking of waterborne polyurethane? The molecular chain of waterborne polyurethane resin is generally linear or branched, and the strength of the film without crosslinking is lower. In order to improve the water resistance, chemical resistance, high temperature resistance and mechanical properties of the cured film, it is necessary to appropriately increase the degree of […]
Service case | Use anti-hydrolysis agent to solve the problem of hydrolysis of TPU products
What is TPU TPU is short for thermoplastic polyurethane elastomer rubber. Compared with traditional plastics, rubbers, and even metals, TPU has many performance advantages such as good low-temperature flexibility, high strength, good oil and acid resistance, environmental protection, and easy processing. With economic development and consumption upgrades, the amount of TPU is increasing year by year. […]
Service Case | Extend the pot life of waterborne polyurethane by replacing the toxic isocyanate curing agent
The main material used by a customer in the post-processing stage of the product is two-component waterborne polyurethane, and isocyanate is used as the curing agent. However, during the specific production process, the customer found that if the formulated water-based polyurethane is not used up in time, the gel will deteriorate the next day and […]
