HIGHER MODULUS FOR ADHESIVE APPLICATIONS

SPUR ⁺ 1050 prepolymer is used in the manufacture of one-part, moisture-curing sealants and as a base resin for medium modulus sealants and adhesives, typically providing the high level of tensile strength often required in industrial and transportation applications. With low viscosity and easy application, SPUR ⁺ 1050 prepolymer generally adheres well to many surfaces without the aid of a primer.

More About SPUR+™ 1050 Prepolymer

A silylated prepolymer manufactured without the use of plasticizer, SPUR ⁺ 1050 prepolymer typically exhibits good water and chemical resistance, as well as high elastic recovery. The high effectiveness of ths hybrid technology can be principally attributed to its combination of the silane-curing mechanism and polyurethane backbone properties.

Formulations developed using SPUR ⁺ prepolymers will generally exhibit fast room-temperature cure and good durability, while the sealants or adhesives they produce contain no unreacted isocyanate from the silylated prepolymer. Typical benefits of the resulting products also include freedom from bubbling during cure and a broadening of formulation latitude to use a wide array of additives and adhesion promoters based on the performance needs of the end users.
