Résumé : |
Alkoxysilanes have been commonly employed as crosslinkers and coupling agents for decades. The instability of silanes in waterborne systems has been a barrier to their effective use in such systems. In this article, advances in silane technology for emulsion polymers are described. The goal is to develop formaldehyde-free, self-crosslinking moisture cure latexes and urethane dispersions. Studies of the factors controlling the shelf stability, cure response and the coating performance are discussed. |
