A METHOD OF ADJUSTING THE TACK VALUE OF A BINDER COMPOSITION

摘要

The present invention is directed to a method for adjusting the tack value of a binder material formed from a composition comprising an emulsion wherein the emulsion comprises water and an emulsifiable prepolymer and wherein the emulsifiable pre-polymer is the reaction product of (i) an isocyanate compound, (ii) a polyol compound, and (iii) a monol compound, the method comprising adjusting the reactive group ratio of component (i) to (ii) to achieve a tack value ranging from 1 to 4 as measured by the TACK TEST METHOD.
