| abstract |
The present invention is to emulsifiable polyisocyanate compositions comprising the reaction product of (i) an aliphatic polyisocyanate and (ii) an emulsifier wherein the polyisocyanate comprises a mixture of two or more isomers of cis-1,3-bis(isocyanatomethyl)cyclohexane, trans-1,3-bis(isocyanatomethyl)cyclohexane, cis-1,4- bis(isocyanatomethyl)cyclohexane or 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. The emulsifiable polyisocyanates are particularly in formulations for producing paints and varnishes, coatings, adhesives, impregnating materials and sealants. |
