Zusammenfassung: | The present invention is to a polyurethane dispersion and products produced therefrom wherein the dispersion contains a polyurethane prepolymer produced from the a reaction of an excess of a polyisocyane with an isocyanate reactive molecule wherein the polyisocyante is a bis(isocyanatomethyl)cyclohexane. Preferably the isocyanate comprises (i) trans-1,4-bis(isocyanatomethyl)cyclohexane or (ii) an isomeric mixture of two or more of cis-1,3-bis(isocyanatomethyl)cyclohexane, trans-1,3-bis(isocyanatomethyl)cyclohexane, trans-1,3-bis(isocyanatomethyl)cyclohexane, cis-1,4-bis(isocyanatomethyl)cyclohexane and trans-1,4-bis(isocyanatomethyl)cyclohexane, with the proviso said isomeric mixture comprises at least about 5 weight percent of said trans-1,4-bis(isocyanatomethyl)cyclohexane. |
