Title: Innovations of Rubin Cai in Polyurethane Coatings
Introduction
Rubin Cai is a notable inventor based in Hong Kong, CN. He has made significant contributions to the field of polyurethane surface coatings, holding 2 patents that showcase his innovative approach to improving in-mold polyurethane foam and resin products.
Latest Patents
Cai's latest patents focus on colored polyurethane surface coatings. These innovations provide improvements for in-mold polyurethane foam and resin products, allowing for bright coloration and reduced colorant migration. The patents disclose the use of easy-to-use polymeric colorants in simplified and environmentally friendly processing methods. The inventive surface coating formulations include polyurethane-reactive polymeric colorants mixed with prepolymer and excess amounts of certain isocyanate compounds. This composition can be applied, for example, by spraying onto a polyurethane prepolymer, which is then introduced into a mold to create a uniquely shaped polyurethane article with a colored surface coating. Upon curing through heat exposure, the coating composition reacts with the polyurethane prepolymer, forming a surface over the internal polyurethane. The excess isocyanate present in the surface coating provides excellent non-migration and non-bleed properties to the polymeric colorant, allowing for the addition of a highly desired, effective polyurethane colorant within the surface coatings.
