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. The silanes are useful as crosslinkers, property modifiers and/or adhesion promoters. Powder adhesives may be similarly formed with the silanes of formula (I). Fillers or pigments, such as titanium dioxide fillers, which are treated with silanes, especially silanes having alkyl, epoxy, acryl, methacryl, polyether, amino, acid anhydride, hydroxyalkyl, carbamato or ureido functionality, may also be usefully employed in powder coating formulations.
