Disclosed is an intumescent curable composition which contains as a resinous binder a flexible polyepoxide resin. The polyepoxide is cured with an appropriate curing agent adapted for the particular resin. An additive component is present which contains a mixture of materials which provide a source of

Flexible intumescent coating composition

A coating composition, containing a fluoropolymer, a film-forming adjuvant resin which is different from the fluoropolymer and adapted to react with the group represented by F in the functional organosilane of formula I and which is selected from the group consisting of acrylic resins, polyepoxide resins, polyester resins, aminoplast resins and mixtures thereof; and an amount effective to promote adhesion of a functional organosilane represented by formula I: ##STR1## wherein A represents an organo group containing from 1 to 18 carbon atoms,

Fluoropolymer based coating composition for adhesion direct to glass

Disclosed is a method of coating the metal side of a mirror by applying to a reflective layer of metal adhered to a transparent glass sheet one or more adherent protective layers wherein the outermost protective layer is a cured coating formed from a liquid coating composition which is curable by exposure to ultraviolet light (UV). The UV curable liquid coating composition has a high degree of resistance to shrinkage upon curing.

Method for improving durability of mirrors utilizing radiation curable

Disclosed is a method of coating a substrate comprising the steps of (A) coating the substrate with one or more applications of a basecoating composition containing (1) an organic film-forming resin, (2) substantially colorless, substantially inorganic microparticles stably dispersed in the basecoating composition, (3) a solvent system for the film-forming resin, and (4) pigment particles to form a basecoat; and (B) coating the basecoat with one or more applications of a topcoating composition containing (1) an organic film-forming resin, and (2) a solvent system for the organic film-forming resin of the topcoating composition, to form a transparent topcoat. The substantially inorganic microparticles prior to incorporation in the basecoating composition range in size from about 1 to about 150 nanometers.

Color plus clear coating system utilizing inorganic microparticles

Disclosed is an essentially solvent-based, organic, high-solids coating composition containing (A) a film-forming binder system containing a crosslinkable resin having a weight average molecular weight of from about 500 to about 10,000; (B) substantially colorless, substantially inorganic microparticles stably dispersed in the coating composition; and (C) a solvent system for the crosslinkable resin. The substantially inorganic microparticles prior to incorporation in the coating composition range in size from about 1 to about 150 nanometers and are in the form of a sol of the microparticles in which the surface of the inorganic microparticles is essentially free of carbon-containing molecules chemically bonded to the inorganic microparticles.

High-solids coating composition for improved rheology control containing

Disclosed is an essentially solvent-based, organic, high-solids coating composition containing (A) a film-forming binder system containing a crosslinkable resin having a weight average molecular weight of from about 500 to about 10,000; (B) substantially colorless, substantially inorganic microparticles stably dispersed in the coating composition; and (C) a solvent system for the crosslinkable resin. The inorganic microparticles prior to incorporation in the coating composition range in size from about 1 to about 150 nanometers and are in the form of a sol of the microparticles in which carbon-containing molecules are chemically bonded to the inorganic microparticles at the surface of the microparticles.

Disclosed are coating compositions containing pigment in a vehicle comprising a dispersion of colloidal silica, a mixture of a hydrolyzable trialkoxysilane and a hydrolyzable dialkoxysilane, alcohol, water and sufficient acidifying agent to provide a pH of the vehicle ranging from about 2.8 to about 6.0.

Pigmented coating composition containing a mixture of alkoxysilanes

Disclosed are coating compositions containing a vehicle comprising a dispersion of colloidal silica, a hydrolyzable alkoxysilane, an alcohol, water, and an acidifying agent selected from a soluble metal acid phosphate, phosphoric acid, and a mixture thereof.
