SPUR+™ Prepolymers for Durable Adhesive and Sealants Additives

The SPUR+™ prepolymer line can help facilitate the creation of adhesives and sealants with excellent adhesion to many surfaces, including aluminum, glass, steel, PVC, porous materials and concrete. These prepolymers can also yield end products with good mechanical properties and exceptional durability indoors and out, with superior resistance to water and other environmental factors. SPUR+™ prepolymers typically exhibit very low shrinkage upon cure, high elastic recovery and good tear resistance as well as rapid tack-free performance and excellent deep section cure under ambient conditions. 

SPUR+™ prepolymers excel in aiding the formulation of room-temperature, one-part moisture cure systems. These prepolymers also avoid the defects that may occur with alternative chemistries when applied to less than perfectly dry substrates and can often eliminate the need for primer. Adhesives and sealants made with SPUR+™ prepolymers can also offer paintability.
