Latest Patents

Kita’s listed patents address colored thermoplastic polyurethane-urea resin powder and self-emulsifiable polyisocyanates.

“Production process of colored resin powder” describes mixing a colorant with a non-phthalic acid plasticizer to form a colored paste, then incorporating that paste into powdery thermoplastic polyurethane-urea resin. The process is designed to reduce uneven coloration and prevent colorant separation that could smear molded products.

“Self-emulsifiable polyisocyanate with high functionality and process for producing the same” concerns a high-functionality polyisocyanate with specified viscosity and functional-group properties. The disclosed production method uses a modified polyisocyanate containing allophanate bonds and a poly(oxyalkylene) glycol monoalkyl ether in a urethanization reaction.
