  • Patent number: 6534568
    Abstract: Powder coating or adhesive formulations include as a component thereof a silane of formula (I) or hydrolyzates or condensates thereof where R1 is a hydrocarbon, acyl, alkylsilyl, or alkoxysilyl group, R2 is a monovalent hydrocarbon group; R3 is alkylene, optionally interrupted with one or more ether oxygen atoms; a is 0 or 1; Z is a direct bond or a divalent linking group; X is an m-valent organic group or H; and m is 1-20.
