  • Patent number: 9580612
    Abstract: An aluminum chelate, a method for manufacturing the same and a photo cured ink including the same are revealed. First rosin resin is modified by epoxy and acrylic acid to get acrylic acid modified rosin resin. Then an aluminum chelating agent undergoes a chelation reaction with the acrylic acid modified rosin resin to form a plastic fluid whose chemical structure contains a photoreactive group and a chelate structure with aluminum. The plastic fluid can be added into photo cured inks so that the photo cured inks have better ink tack, ink flow, color density and stability.

    Abstract: Thermally cross-linkable photo-hydrolyzable inkjet printable polymers are used to print microfluidic channels layer-by-layer on a substrate. In one embodiment, for each layer, an inkjet head deposits droplets of a mixture of hydrophobic polymer and cross-linking agent in a pattern lying outside a two-dimensional layout of the channels, and another inkjet head deposits droplets of a mixture of poly(tetrahydropyranyl methacrylate) PTHPMA (or another hydrophobic polymer which hydrolyzes to form a hydrophilic material), cross-linking agent, and a photoacid generator (PAG) in a pattern lying inside the two-dimensional layout of the channels. After all layers are printed, flood exposure of the entire substrate to UV radiation releases acid from the PAG which hydrolyzes PTHPMA to form hydrophilic poly(methacrylic acid) PMAA, thereby rendering the PTHPMA regions hydrophilic. The layers of these now-hydrophilic patterned regions together define the microfluidic channels. The cross-linking agent (e.g.

  • Patent number: 8420174
    Abstract: The present invention relates to a composition for coating metallic surfaces, comprising a binder component; a corrosion inhibitor polymer based on an ethylenically monocarboxylic and dicarboxylic acid and, if appropriate, further ethylenical monomers, a solvent component, and, if appropriate, crosslinkable components, and also pigment/filler components. The invention further relates to processes for its preparation and also to methods of coating a metallic surface using the composition, to coated metallic surfaces thus obtained, and to the use of the composition as a primer, particularly in coil coating or in atmospheric corrosion control. After drying, the applied layer preferably has a thickness of at least 3.1 ?m and is therefore thicker than a typical pretreatment layer.

  • Patent number: 8410211
    Abstract: The invention is a method of producing an essentially electrically neutral polymer dispersion, comprising a polymerizing one or more monomers in the presence of a nonionic surfactant, wherein the polymerization preferably occurs in the absence of ionic surfactants. The invention also includes methods of producing positively or negatively charged polymer dispersions comprising producing the essentially nonionic polymer dispersion and further adding a cationically-charged or anionically-charged surfactant or electrolyte. The invention further includes dispersions produced by the methods of the invention and polymer films and powders produced from these dispersions.

  • Publication number: 20130035434
    Abstract: Curable rubber compositions and cured articles are based on the use of zinc activator compositions for the sulfur cure. Activator compositions contain zinc and a polymeric component having a plurality of COOH groups, at least some of which are neutralized with the zinc. With polymeric zinc activators, sulfur cure can be activated at levels of zinc below those used in conventional systems.

  • Publication number: 20120301991
    Abstract: A composition including a mixture of a cross-linking agent and a first polyolefin including a functional monomer selected from among unsaturated carboxylic diacid or carboxylic acid anhydrides, the unsaturated carboxylic acids and the unsaturated epoxides being suitable for cross-linking with a second polyolefin in order to form an assembly adhered to a substrate, said assembly and the substrate forming an integral structure having two separate layers, characterized in that the amount of cross-linking agent is no lower than 5% of the total weight of the composition. Said masterbatch enables, even in the absence of silanes, cross-linking of polymers, in particular polyolefins, in order to increase the adhesive capacity thereof to substrates such as polymers, metals, metal oxides or silicon. Said masterbatch can be used in particular for encapsulating photovoltaic cells.

  • Publication number: 20120302660
    Abstract: A process for applying a heat sealable layer to a substrate in which the substrate is provided with a coating composition containing a cyclic imide, which can be a maleimide, an itaconimide, a citraconimide or a 2,3 dialkyl maleimide. Preferably the coating composition is brought on the substrate from a water borne formulation in which the coating composition containing a cyclic imide is dispersed in the water phase and the coating composition containing a cyclic imide is a copolymer of cyclic imides and vinylic co-monomers, preferably a co-polymer of cyclic imides and styrene. The dispersed product in the water phase has a particle size between 20 and 500 nm, preferably between 30 and 200 nm, and the particles have a core-shell structure.
