摘要:
Unsaturated cycloaliphatic esters like higher hydrocarbyl, functionally substituted or polyunsaturated cyclohex-3-ene carboxylates, made directly by cycloaddition of dienes with dienophillic (meth/eth)acrylates, and their derivatives like epoxides and urethanes, provide useful thermal and radiation curable coatings, inks, sealants, adhesives, solvents, acid scavengers, and intermediates for other uses.
摘要:
This invention is directed in general to polymers (including oligomers) that contain carboxyl-terminated lactone acrylates, to a process for their preparation, and to coating, ink, adhesive, and sealant compositions (including the cured coatings, inks, adhesives, and sealants) that are obtained by crosslinking the above compositions by various means. The cured compositions, which are, for example, high-quality industrial finishes, are made by incorporation of various conventional crosslinking agents and other normally-used formulating ingredients with the polymeric compositions of the invention.
摘要:
This invention is directed to adducts of at least two poly(active hydrogen) organic compounds and a polyepoxide comprising the reaction product of at least two poly(active hydrogen) organic compounds differing as to classification and a polyepoxide containing two or more epoxy groups per molecule, said poly(active hydrogen) organic compounds being employed in an amount at least sufficient to effect substantially complete reaction of the epoxy groups of the polyepoxide. The adducts are useful in the formulation of high solids coating compositions, polyurethane elastomers, inks, sealants, adhesives and the like.
摘要:
This invention is directed to photocopolymerizable compositions comprising an epoxide containing two or more epoxy groups, a polymer/poly (active hydrogen) organic compound and a photoinitiator. The cured coating compositions exhibit a clear appearance, good water resistance and can have utility as automotive finishes, can finishes, appliance finishes, general metal finishes, adhesives, printing inks, and the like.
摘要:
Dispersions of high molecular weight, essentially non-polymerizable vinyl resins in mixtures of radiation curable monofunctional and polyfunctional acrylyl monomers and/or oligomers. The dispersions are useful as coating and ink compositions.
摘要:
High solids, low energy curing compositions of (1) a carboxyl-modified polycaprolactone polyol which is the reaction product of a polycaprolactone polyol and an intramolecular carboxylic acid anhydride, (2) a monocarboxylic acid compound, (3) a stannous salt and (4) a polyepoxide. The compositions are useful as inks or coatings.

Novel ester diol alkoxylate urethane-acrylates comprising the reaction products of an ester diol alkoxylate, such as 2,2-dimethyl-3-hydroxypropyl 2,2-dimethyl-3-hydroxypropionate, and an organic polyiosocyanate, capped by an hydroxyalkyl acrylate and curable compositions thereof.
摘要:
Derivatives of esterdiol alkoxylates obtained by reaction thereof with an epoxide, as well as the anhydride capped products thereof. Formulations containing the above are also claimed.
摘要:
Blends of derivatives of esterdiol alkoxylates obtained by reaction thereof with an anhydride, isocyanate or epoxide and an acrylic latex. The blends are useful as coatings.
