摘要:
A coating composition that exhibits high cure speed is described. The coating composition includes one or more monomers, one or more oligomers, and a photoinitiator. The coating composition further includes a photosensitizer that acts in cooperation with a photoinitiator to increase cure speed.
摘要:
This invention relates to a precast liquid photopolymeric plate, a flexible relief plate derived therefrom and a method for producing the precast liquid photopolymeric plate. Particularly, a flexible container having a top layer, a bottom layer, and a photosensitive layer defined by a continuous frame having planar surfaces, the frame comprising a cured photopolymer preparation, the top and bottom layer being adhered to each side of the photosensitive layer so as to seal the container, in which the top and bottom layer are sheets being transparent to photo irradiation used in curing the photopolymer and being inert to the photopolymer; and an uncured photopolymer preparation contained within the container.

摘要:
The present invention relates to a photo-curable adhesive composition comprising a (meth) acrylate capped aliphatic polyurethane having an average number of ethylenically unsaturated groups less than 1, a mono-functional (meth) acrylate monomer or oligomer and a photoinitiator. The adhesive composition can be used in a method of bonding a substrate to a liquid crystal display. The adhesive composition according to the present invention has improved side curing depth.
摘要:
The invention relates to a crosslinkable fluorinated urethane compound having at least one ethylenically unsaturated functional group. Such compounds are useful as coatings additives such that, when the coating is applied to a substrate, the additive compound is allowed to first migrate to the surface and subsequently crosslink to form a durable oil-, dirt-, and water-repellent surface.
摘要:
A three-dimensional printing photocurable composition includes from 20 wt% to 70 wt% of an urethane acrylate component, from 20 wt% to 60 wt% of a multifunctional epoxide component, from 1 wt% to 15 wt% of a monomer component, and from 1 wt% to 8 wt% of a photoinitiator component, based on the total weight of the composition. The urethane acrylate component includes the capping reaction product of an acrylate and an isocyanate terminated prepolymer and the isocyanate-terminated prepolymer is the reaction product of a polyisocyanate and at least one polyol having a molecular weight of at least 3000 g/mol. The multifunctional epoxide component includes one or more multifunctional epoxides. The monomer component includes at least one of a multifunctional acrylate monomer and a multifunctional vinyl ether monomer.
摘要:
The invention provides anaerobic curable compositions comprising a (meth)acrylate component, at least a portion which comprises a (meth)acrylate-functionalized bio-renewable oleaginous polyurethane polymer, and methods of their production and use. These compositions provide excellent adhesion especially on oily surfaces.
摘要:
A coated article is disclosed that includes a metal substrate and a coating composition disposed on at least a portion of the metal substrate. The coating can be formed from a composition that includes an acrylic copolymer, which is preferably the reaction product of ethylenically unsaturated monomers and a functional monomer. The functional monomer can be the reaction product of a multifunctional isocyanate and an ethylenically unsaturated nucleophilic monomer. The functional monomer preferably includes a blocked isocyanate group. The articles can be useful for packaging foods and beverages.
