Abstract:
A method is provided for making a silver-containing concentrate. The method comprises the step of isolating the solid materials from a liquid composition that comprises (a) silver cation, (b) a polymer that has pendant unsaturated or aromatic heterocycles, and (c) solid particles having median diameter of 2 mm or smaller.
Abstract:
A process for the preparation of a thixotropic aqueous coating composition comprising the steps of: i) providing an aqueous dispersion of a binder system comprising carbonyl and hydrazide functional groups for crosslinking; and ii) reacting in the aqueous dispersion, an ether amine with a tris(isocyanate) isocyanurate to form a polyurea sag control agent.
Abstract:
To provide a back coating composition capable of forming a back coating film which is scarcely susceptible to acid erosion, and a mirror excellent in acid resistance. Using a back coating composition comprising a thermosetting resin, a pigment and a dispersant, wherein as the dispersant, an amino group-containing polymer having an amine value of at least 20 mgKOH/g and having no acid group is contained, a back coating film 14 is formed on a metal film (silver mirror film 12 or metal protective film 13) of a mirror 10.
Abstract:
A clearcoat coating composition contains a carbamate-functional film-forming material, a carbinol-functional, nonlinear siloxane resin, and an aminoplast crosslinking agent. The clearcoat composition provides excellent high-bake repair adhesion of a repair coating layer over the clearcoat coating.
Abstract:
A curable film-forming coating composition, typically a clearcoat, having improved compatibility over waterborne and solventborne basecoats. The composition includes a film-forming binder comprising a carbamate material, a curing agent, typically a monomeric melamine curing agent, and a hydroxy functional silane component. When used as a clearcoat over a standard pigmented basecoat, the resulting coating provides a substantially wrinkle free appearance and excellent adhesion to both waterborne and solventborne basecoats.
Abstract:
The present invention is directed to a polyester resin for use in a coating composition. The polyester resin is the reaction product of a first compound comprising a plurality of hydroxyl groups, a lactone compound, a carboxylic acid anhydride, an epoxy compound having at least one epoxy group, and a carbamate compound. The present invention is also directed to a coating composition including the polyester resin and to a method of preparing the resin.
Abstract:
Provided is a curable coating composition comprising a reactive compound having one or more structures of the formula: X-Cn(R1)(R2)-C(R0)(Y)-Cn'(R3)(R4)(R5) wherein X is a primary carbamate group, Y is a hydroxy or halide group, n is an integer of 2 or more, n' is an integer of 1 or more, and R0, R1, R2, R3, R4 and R5 may be H or a group selected from alkyl groups, aliphatic groups, cycloaliphatic groups, aromatic groups and mixtures thereof, with the provisos that at least one R1 or R2 group is selected from the group consisting of aliphatic groups, cycloaliphatic groups, aromatic groups, and mixtures thereof, and in substantially all structures primary carbamate group X is attached to a carbon atom having a lower degree of substitution than a carbon atom to which functional group Y is attached.
Abstract:
The invention provides curable coating compositions comprising an aqueous dispersion comprising a stabilizing resin (P1) and a compound (P2) comprising functional groups reactable with a crosslinking agent. Compound (P2) is dispersed into stabilizing resin (P1). The coating compositions of the invention may further comprise an optional crosslinking agent (P3) which may or may not be dispersed into stabilizing resin (P1). In a particularly preferred embodiment, both the stabilizing resin (P1) and compound (P2) will comprise functional groups which are carbamate or are convertible to carbamate.
Abstract:
The invention provides carbamate-functional resins and coating compositions incorporating said resins that have improved adhesion with respect to subsequently applied films or coatings. More particularly, the invention relates to carbamate-functional addition polymers having at least 250 grams of polymer per carbamate group which are made with less than 35 percent by weight of nonfunctional monomers, preferably with less than 20 percent by weight and most preferably from 0 to less than 10 percent by weight, based on the total weight of the polymer. The invention further provides a method of making a carbamate-functional polymer and carbamate-functional polymers made by the claimed method. Finally, the invention provides a method for improving the adhesion of a first coating composition to a subsequently applied material as well as a method of making a composite comprising a coated substrate, an adhesive composition, and a glass having at least one surface.
