Carboxylated latex resins and neutralized carboxylated water-soluble polymers are crosslinked with aliphatic or cycloaliphatic polyfunctional polycarbodiimides or mixed aliphatic-aromatic polyfunctional polycarbodiimides.

Low temperature crosslinking of water-borne resins

Mixed aliphatic/aromatic polycarbodiimides can be prepared by first heating aliphatic mono- and diisocyanates with a phospholene oxide catalyst and then feeding the aromatic mono and/or diisocyanates in an inert solvent to the reaction mixture. These polycarbodiimides find use in a method for cross-linking carboxylated latexes.

Method of using mixed aliphatic/aromatic polycarbodiimides

Mixed aliphatic/aromatic polycarbodiimides can be prepared by first heating aliphatic mono- and diisocyanates with a phospholene oxide catalyst and then feeding the aromatic mono and/or diisocyanates in an inert solvent to the reaction mixture, thus preparing cross-linking agents for carboxylated latexes used in making roofing materials, hardboard, pressure sensitive adhesives and the like.

Method of making mixed aliphatic/aromatic polycarbodiimides

Acrylated urethane silicone compositions are formed from the reaction of a silicone carbinol, a polyisocyanate and a hydroxy-functional acrylate. These compositions are useful as components of improved radiation-curable coating compositions.

Acrylated urethane silicone compositions

A fast curing foamable composition useful for the production of fabric-like materials comprises a resin or latex formulation and a mixture of a highly ethoxylated alkylphenol, an alkali metal N-alkyl sulfosuccinamate and an alkali metal alkyl sulfate.

Foamable composition

Acrylated organomodified silicone compounds are formulated into radiation-curable varnishes applied in thin films to the surface of uncured, oil-based ink prints in line with the printing operation. The coating cures to a tack-free high gloss surface.

Acrylated silicones as radiation-curable overprint varnishes

A class of materials termed acrylated epoxy silicones have been synthesized. In one of its simplest forms, the final product can be the reaction product of an epoxy silicone and acrylic acid. These novel materials can be used per se or in formulations as coatings compositions that are readily cured to yield solid, protective, high gloss films.

Radiation-curable acrylated epoxy silicone compositions

Acrylated urethane polycarbonate compositions are formed from the reaction of a polycarbonate polyol, a polyisocyanate and a hydroxy-containing acrylate monomer. These compositions are useful as components of improved radiation-curable compositions.

Radiation-curable acrylated urethane polycarbonate compositions

Radiation-curable acrylated urethanes having a lower viscosity than heretofore achievable without dilution are produced by an improved process that involves first reacting a monohydroxy-functional acrylate with a polyisocyanate followed by the reaction of the product mixture produced with a polyol. The acrylated urethanes so produced are useful in radiation-curable coatings.
