Chain extender JTA95 J5801 Waterborne polyurethane Combine the performance of emulsifier and chain extender
Chain extender JTA-95 is an aqueous solution of sodium sulfamate. The amino groups at positions 1 and 2 combine the performance of emulsifier and chain extender in the process of synthesizing aqueous polyurethane dispersions. The polyurethane dispersion synthesized with it improves the stability and compatibility with other anionic or nonionic dispersions. Due to the lower ammonia value, the hydrolysis stability of the polyester in the aqueous polyurethane dispersion is improved.
