Abstract of  TW201623354 (A):

A kind of two-component solvent-free reactive polyurethane hot-melt adhesive and its preparation method. The said two-component solvent-free reactive polyurethane hot-melt adhesive comprises component A and component B, wherein component A is a difunctional or multifunctional prepolymer that is terminated with an isocyanate, wherein the isocynante content is of 2% to 25%; component B is a difunctional or multifunctional prepolymer that is terminated with hydroxyl, wherein the hydroxyl has the value in the range of 10 to 250mgKOH/g; at 50DEG C, and the viscosity of the component A and component B is not less than 1000cps. The present invention solves the problem of having no initial viscosity for two-component solvent-free reactive polyurethane hot-melt adhesive, which has comparatively low-cost and broader applicability than that of ordinary single-component solvent-free reactive polyurethane hot-melt adhesive.
