    摘要: Both higher corrosion resistance and paint adherence are given to film formed on the surfaces of metals by treating the surfaces with aqueous solution of one or more materials selected from the group consisting of water soluble vinyl monomer, water soluble high polymer and then irradiating ionizing radioactive rays on the nearly dried surface film. When a water soluble inorganic compound is mixed with the above mentioned aqueous solution, the film properties are greatly improved.

    摘要: A composite dental filling material comprises a mixture of a finely divided, inert inorganic filler and the reaction product of an organic aliphatic diisocyanate and a hydroxylakyl acrylate or methacrylate. The filling material also contains at least one other ethylenically unsaturated monomer, namely a bisphenol A derivative having at least two terminal acrylate or methacrylate ester groups. Further the filling material may also contain a catalyst and an activator.

    摘要: A PROCESS FOR PRODUCING THE IMPROVED AQUEOUS ACRYLICCONTAINING EMULSIONS FOR BLISTER RESISTANT PAINTS AND TO THE PRODUCTS THEREOF PREPARED BY THE ADDITION OF A AMINO RESIN PRIOR TO OR DURING THE POLYMERIZATION IN AN AQUEOUS SOLUTION, OF AN ALKYL ESTER OF A POLYMERIZABLE ALPHA BETA UNSATURATED MONOCARBOXYLIC ACID AND A MONOMER CONTAINING A SINGLE H2C=C GROUP. THE POLYMERIZATION OCCURS IN THE PRESENCE OF A POLYMERIZABLE UNSATURATED CARBOXYLIC ACID, A CATALYTIC AMOUNT OF A FREE RADICAL POLMERIZATION CATALYST AND A SURFACTANT. THE INTERPOLYMER FORMED IS CAPABLE OF CONTINOUS FILM FORMATION AT 40*C. OR BELOW.

    摘要: A reactive metal oxide or metal hydroxide, such as ZnO, MgO, HgO or Ba(OH)2 and acrylic or methacrylic acid are added to a liquid, hydrophobic, essentially solvent-free coating vehicle capable of being cured by high-energy radiation. The resulting coating composition, as compared to the vehicle alone, can be cured with lower radiation doses, is less susceptible to oxygen inhibition of curing with ionizing radiation and exhibits a thixotropic viscosity which prevents excessive penetration of the coating into porous substrates and contributes non-drip, low-flow characteristics to the composition.
