Titre : Silane curing agents in waterborne coatings : Study of advances in silane technology for emulsion polymers Type de document : texte imprimé Auteurs : Ming Jang Chen, Auteur ; Philibert E. Ramdatt, Auteur ; Weizhen Cai, Auteur Année de publication : 1998 Article en page(s) : p. 532-537 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits 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. Note de contenu : - Hindered silane monomers
