SPUR+* 1050MM Prepolymer


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

More About SPUR+* 1050MM Prepolymer

A silylated prepolymer manufactured without the use of plasticizer, SPUR + 1050MM prepolymer normally exhibits good water and chemical resistance, as well as high elastic recovery. This hybrid technology can be highly effective because of the combination of the silane-curing mechanism and polyurethane backbone properties. Formulations developed using SPUR + prepolymers typically offer 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 the formulation latitude compared to most conventional polyurethane technologies. The benefits of these prepolymers can enable formulators the freedom to use a wide array of additives and adhesion promoters, based on the performance needs of the end users.
