IPC: C03C17/32
Filed: 1955-12-06
Abstract: Glass surfaces such as fabrics or films are coated with a composition comprising 0.25 to 5.0 per cent by weight of a saturated water-soluble polyester resin, from 0.1 to 2.0 per cent by weight of an aliphatic amine or amide containing a carbon chain of at least 8 carbon atoms which may be interrupted by nitrogen atoms, or quaternary derivatives of such amines, from 0.1 to 10.0 per cent by weight of a Werner complex compound in which an acido group is co-ordinated with a trivalent nuclear chromium atom and contains less than 7 carbon atoms in an aliphatic group and in which the aliphatic group also contains a highly reactive group, from 0.01 to 0.5 per cent by weight of a hydrophilic colloid, from 0.005 to 0.05 per cent by weight of a polyoxyalkylene condensation polymer or from 0.15 to 2.0 per cent by weight of its ester and from 82.45 to 99.535 per cent by weight water.  The coated glass materials may be dried and heated to 200 DEG  to 300 DEG  F. and may be used in the production of laminates and reinforced plastics with thermosetting and thermoplastic synthetic resins.  The polyester resin component may be formed from a saturated dibasic acid and saturated dihydric alcohol or from other polybasic acids and polyhydric alcohols at a water-soluble stage of polymerization.  The hydrophilic colloid may be polyvinyl alcohol, casein, an alginate, a cellulose ether or ester, e.g. methyl cellulose, carboxymethyl cellulose.  The amine or amide component may be pelargonic acid amide, tetraethylene pentamine reacted to contain 5 methallyl side chains a condensate of tetraethylene pentamine with less than 5 mols. of stearic acid solubilized with acetic acid or the hydrochloride of the aliphatic amine mixture derived from coconut oil fatty acids.  The polyoxyalkylene condensation product may be a conjugate compound in which polyoxyalkylene groups are attached to an organic radical derived from a polybasic carboxylic acid having a M.W. less than 200 at the site of a reactive hydrogen atom and polyoxyethylene groups are attached to polyoxypropylene chains, or an alkylene oxide condensation product of a dimerized or trimerized fatty acid (linoleic) alkylolamide.  The Werner complex may be a chromic compound containing an organic group which is either unsaturated, has a high dipole moment, a labile hydrogen atom or a highly negative group adjacent an available free hydrogen.  Methacrylate chromic chloride, methallyl chromic chloride and vinyl chromic chloride are specified.  The composition may also contain an organo silane or hydrolysis product thereof, two or more hydrolysable groups and an organic group attached directly to the silicon atom. Vinyltrichlorosilane, vinyltriacetoxysilane, styryldihydroxysilane and allyltriacetoxy silane are specified. The composition is adjusted to a pH of 4.5 to 6.0 by adding acetic acid or ammonia as necessary. The coated materials may be laminated with materials of unsaturated polyester resins, epoxy resins, phenol-formaldehyde, urea-formaldehyde or melamine-formaldehyde resins, polyvinyl chloride vinyl-chloride-vinyl acetate copolymers, polyamides, polyalkylacrylates, polyethylene, butadiene-acrylonitrile or butadiene-styrene copolymers.ALSO:Glass fibres or fabrics are coated with a composition comprising 0.25 to 5.0 per cent by weight of a saturated water-soluble polyester resin, from 0.1 to 2.0 per cent by weight of an aliphatic amine or amide containing a carbon chain of at least 8 carbon atoms which may be interrupted by nitrogen atoms, or quaternary derivatives of such amines, from 0.1 to 10.0 per cent by weight of a Werner complex compound in which an acido group is co-ordinated with a trivalent nuclear chromium atom and contains less than 7 carbon atoms in an aliphatic group and in which the aliphatic group also contains a highly reactive group, from 0.01 to 0.5 per cent by weight of a hydrophilic colloid, from 0.005 to 0.05 per cent by weight of a polyoxyalkylene condensation polymer or from 0.15 to 2.0 per cent by weight of its ester and from 82.45 to 99.535 per cent by weight water.
