The present invention is directed to a UV curable coating composition, which includes one or more monomers, one or more multifunctional oligomers, one or more pigments, one or more photoinitiators, and volatile organic solvent. The coating composition can be used as a primer in repairing and refinishing automobiles. The coating composition provides short drying times and a cured coating that does not need to be wiped. A method of applying the coating composition is also provided.

Coating composition and method for coating substrates

The present invention relates to a substrate coated with a coating composition wherein the coating composition comprises a crosslinkable component and the crosslinkable component is a mixture of two different and optionally three different acrylic polymers. Each acrylic polymer has functional groups present that are reactive with a crosslinking component. The functional groups present on each polymer have different rates of reactivity with the crosslinking component.

Coated substrate

The present invention is a coating composition comprising a tricure acrylic resin which comprises functionality having different rates of reactivity to crosslinking compounds such as, for example, diisocyantes and polyisocyanates.

Tricure acrylic resins

This invention relates to a protected organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has a formula according to; RRRSn[CH(OX)R], wherein R, R, and Rare the same or different and represent an optionally substituted hydrocarbyl, aromatic, alkoxide, amide, halide or stannyl group, Rrepresents an optionally substituted hydrocarbyl or optionally substituted aryl group. a, b, and c are independently 0, 1, 2, or 3; d is 1, 2 or 3; and a+b+c+d=4; and X is an acid-labile or moisture-labile protecting group. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.

This invention relates to coating compositions and more particularly to highly productive coating compositions that quickly harden for sanding or buffing by incorporating therein a polyisocyanate adduct mixture into the coating composition as the crosslinking material. Such coatings are particularly useful for refinishing automobiles and trucks.

Process for coating thermoplastic substrates with a coating composition containing a non-aggressive solvent

The use of a two layer photoimageable, aqueous processable, resist with a hydrophic binder in the outermost layer provides a permanent coating highly resistant to printed circuit processing chemicals. This resistance results in levels of adsorbed or absorbed ionic contamination less than 14 micrograms per square inch.

Organic vehicle for electronic composition

Process of enlarging image areas covered by a stencil or relief image area formed in a photopolymer mask consisting essentially of (a) contacting said image area with a swelling agent and optionally a diluent to effect enlargement, and (b) removing excess swelling agent, i.e., evaporation, air impingement including heating. Additional image enlargement is possible by further contacting the image with a more concentrated swelling agent. The process is particularly useful in enlarging halftone image dots of photopolymer litho masks wherein the halftone image areas consist of hardened upper skins which rest on softer undervolumes having a lesser degree of polymerization or hardening.

Enlargement of photopolymer images in photopolymer mask

A process for preparing a two layer printed circuit having conductive interconnections wherein at least one layer of a photoadhesive composition is applied to a substrate bearing an electrically conductive circuit pattern and exposing said photoadhesive layer or layers through a circuit image of three different optical densities, i.e., zero, gray and opaque, removing portions of the photosensitive layer by solvent washout, applying finely divided metal, alloy or plating catalyst to adherent image areas, optionally curing the printed circuit, e.g., heating or ultraviolet exposure and plating to form an interconnected electrically conductive circuit pattern. Multilayer printed circuits can also be prepared by repeating the steps using additional layers of photoadhesive material.
