Title (EN) PROCESS FOR IMPROVING ADHESION OF POLYSILOXANE COATINGS TO POLYMERIC SUBSTRATES AND PRODUCTS PREPARED THEREBY
(FR) PROCEDE DESTINE A AMELIORER L'ADHESION DE REVETEMENTS EN POLYSILOXANE SUR DES SUBSTRATS POLYMERES ET PRODUITS PREPARES SELON CE PROCEDE
Abstract:
(EN) A coating process and coating composition are disclosed wherein the coating is a silica sol and a polymerizable silane which have had their alkali metal cation content reduced to prevent blistering and loss of adhesion.
(FR) Procédé et composition de revêtement dans lequel le revêtement est un mélange de sol de silice et de silane polymérisable dont la teneur en cations de métaux alcalins a été réduite pour prévenir les boursouflures et le manque d'adhesion.
