More About SPUR+* Y-15990 Prepolymer

SPUR+ Y-15990 prepolymer enables broad formulation latitude because of its low viscosity. In formulations employing this prepolymer, exceptional properties of the cured product including tear, UV, heat and water resistance can be realized. Tensile strength at break, elongation at break, modulus at 100% extension and hardness are among the mechanical properties that can be optimized in roof coatings utilizing SPUR+ Y-15990.

With SPUR+ Y-15990 prepolymer, roof coating formulations can be tailored to display the desired balance of elongation, hardness and tear resistance, along with low viscosity. The cured coatings of these formulations have demonstrated excellent weatherability characteristics.
