Abstract

A method for modifying cure speed of a condensation reaction curable involves converting the higher alkoxy groups on ingredient (A) to lower alkoxy groups (such as methoxy groups) using ingredients (B) and (C). Ingredient (A) is a substrate (polymer) having an average, per molecule, of at least two higher alkoxy group functionalized silyl end-blocking groups. Ingredient (B) is a reactant having lower alkoxy groups bonded to silicon. Ingredient (C) is a transesterification catalyst. It is thought that the higher alkoxy groups on ingredient (A) cure too slowly to be practical for many moisture curable sealants and adhesives. As used herein, the term higher alkoxy group means an alkoxy group having more carbon atoms than the lower alkoxy group on ingredient (B). By exchanging some or all of the higher alkoxy groups on ingredient (A) with lower alkoxy groups from ingredient (B), it is thought that cure speed of a sealant or adhesive composition can be increased. Furthermore, it may be possible to control cure speed of the composition by varying the amount of lower alkoxy groups present. And, it may be possible to control physical properties, such as modulus, by varying the amounts of ingredients (A) and (B) relative to each other.
