Abstract:
The present invention relates to the use of different-sized polymeric microparticles in hydraulically setting building material mixtures for the purpose of enhancing their frost resistance and cyclical freeze/thaw durability.
Abstract:
A process for preparing an encapsulated particulate solid using an epoxy functional cross-linking agent and a carboxylic acid functional dispersant wherein the cross-linking agent has one or more oligomeric dispersing group and/or the dispersant has an acid value of at least 125 mg KOH/g. The resultant solids are useful in, for example, ink jet printing inks.
Abstract:
A method of preparing a shaped article having a photochromic coating thereon, and curable photochromic powder coating compositions are described. The method includes: applying at least one curable powder coating composition to at least a portion of the interior of a mold, e.g., a lens mold, wherein at least one of the applied powder coating compositions includes a photochromic amount of photochromic material; curing at least partially the applied photochromic powder coating; charging a polymerizable organic casting composition into the mold; polymerizing the casting composition; and removing a shaped article having a photochromic coating on at least a portion of its surface from the mold.
Abstract:
The invention relates to a coating composition for PVC sections, based on a polymeric vehicle, a crosslinking agent, and a thermoplastic resin powder. The coating composition is particularly useful for coating PVC sections for windows, shutters, and doors. PVC joinery coated with the composition of the invention has exceptional impact strength and resistance to abrasion, friction, and inclement weather.
Abstract:
An aqueous coating composition for the manufacture of precoated metal is based on an aqueous resin having a carboxyl group in a molecule and neutralizable with a basic material as a binder, the aqueous resin being selected from an acrylic copolymer resin, polyester resin, and polyurethane resin. A mono- or poly-carbodiimide compound is blended with the aqueous resin. The composition forms a coating having improved chemical resistance, water resistance, and adhesion to sheet metal.
Abstract:
The use of a two layer photoimageable, aqueous processable, resist with an amphoteric binder in the layer laminated directly to a printed circuit board provides a permanent coating with improved adhesion throughout the lamination process while maintaining other desirable properties such as storage stability and circuit encapsulation.
Abstract:
A thermosetting composition comprising (A) a carboxyl group-containing polyol resin, (B) a hydrolyzable silyl group-containing polymer, and at least one member selected from the group consisting of (C) a dehydrating agent and (D) an alcohol. The composition of the present invention is excellent in the physical properties of the film as well as the storage stability of the coating composition compared to the known compositions containing the curing catalyst.
Abstract:
A formable, weldable, removable protective coating composition for use on metals, said coating comprising a combination of a base-neutralized acid-funtional copolymer and a wax lubricant, and further comprising a removability enhancing means such as phosphoric acid as an additive to the coating composition.
Abstract:
Disclosed is a curable composition which is superior in chemical resistance and weather resistance and appearance by the use of oxazolidine compounds, comprising (A) a compound having a carboxylic anhydride group, (B) an oxazolidine compound and (C) a polymer containing an alkoxysilyl group. An epoxy compound (D) may be added to the composition.
Abstract:
A liquid coating composition is provided which comprises, as a binder, an addition polymer containing on average 2 or more pendant activated unsaturated groups and, as a crosslinking agent, a compound containing on average 2 or more primary amino groups. The pendant activated unsaturated groups of the addition polymer are based upon fumaric, maleic and/or itaconic acid and/or anhydrides thereof. The liquid coating compositions of the present invention provide the particular advantage of rapid cure at ambient temperatures.
