Abstract: A surface coating composition is used to confer anti-stick and water-repellent properties to a mineral-based article comprising OH groups on its surface. The system consists of a silane of formula RnSiX4-n (n = 1 or 2, and X is a hydrolysable group), a metallic alcoholate with at least 3 hydrolysable branches corresponding to the formula RMX3 or MX4 (M is a hydrolysable branch), and an aqueous acidified mixture containing a lower alcohol. Also claimed are (i) the process for applying the coating on the substrate and (ii) the finished film obtained with anti-stick and repellent properties.

Abstract: A rod of material having a cross-sectional compsn. gradient is obtd. by simultaneously passing a core stream of one compsn. and a concentric annular sheathing stream of a different compsn. into a casting tube. Appts. includes at least two reservoirs having concentric discharge orifices through which the materials flow by gravity into a concentric casting tube. A heating system controls the temp. profile of the material as it flows through the tube and provision is made for controlling the rate of flow. From its outlet the materials pass in laminar flow to a concentric mould of greater cross-section. Pref. the compsn. gradient is controlled by adjusting the flow rates and temp. at a selected interface position between core and sheath.

Date Apr. 17, 1997A protective coating which imparts non-stick and abrasion resistant properties, as well as hydrophobic properties to an inorganic article, the coating being the composition product between hydroxyl groups on the surface of the inorganic article and a composition comprising a silane, a metal alkoxide and an acidified aqueous mixture of a lower alkanol. The silane content is at least 50% of the total sum of the silane plus the metal alkoxide. The metal alkoxide is at least 5% and preferably 10% of the total sum of the silane plus the metal alkoxide.
