Adhesive compositions |
摘要 |
Pressure-sensitive adhesives which are mixed immediately prior to application, or need drying equipment tend to be expensive in use while those applied as hot melts tend to have poor heat resistance. According to the invention an adhesive composition curable by atmospheric moisture is provided, the composition comprising a prepolymer component with isocyanate functionality between 2.0 and 3.0 together with one or more polyetherurethane prepolymers having NCO groups available for reaction with water for chain extension, the cured adhesive composition having a glass transition temperature below 20 DEG C.
