Silane-terminated polyurethanes have become increasingly appealing for use in the manufacturing of adhesives, sealants and coatings. Formulations based on SPUR⁺prepolymers typically feature fast room-temperature cure and freedom from bubbling during cure and allow a broad formulation latitude when compared to conventional polyurethane technologies.

SPUR⁺prepolymer can enable the formulator to use a wide variety of additives and adhesion promoters to optimize a range of performance needs that include:

• Enhanced elasticity and durability

• Primerless adhesion to many organic and inorganic, porous and nonporous substrates
• Excellent chemical resistance, such as to automotive fluids
• Minimal shrinkage
• Exceptional weatherability
• Paintability
• Non-staining performance on porous substrates
• Candidacy for clear adhesives
• Lower VOC-formulated products
• Does not contribute any unreacted isocyanates

Key Features and Typical Benefits

• Broad formulation latitude
• Easy application characteristics
• Excellent adhesion to many surfaces without primer
• High durability indoors and outdoors
• Good water and chemical resistance
• High elastic recovery
• Long shelf life
