As barium sulfate which is used as a filler of a resin composition for an electronic equipment, a precipitated barium sulfate which is synthesized from barium sulfide contains a sulfur component as an impurity so that metal parts such as electrodes of electronic parts may be deteriorated and corroded by a hydrogen sulfide component volatilized from the barium sulfate to reduce the function, the durability, and the reliability of electronic equipment when used for resin compositions such as an ink, a film, and a sheet which are used for an electronic equipment. Barium sulfate composite particles having a zinc compound adhered to the particle surface and having an average particle diameter of 0.01 to 10 µm.

The present invention provides an unsaturated polyester resin composition for producing a molding resin for use in a switched reluctance motor. The unsaturated polyester resin composition comprises an unsaturated polyester, a crosslinking agent, a curing agent, a low profile additive, a filler, and a reinforcing fibrous material. The content of the filler is from 100 parts by mass to 800 parts by mass with respect to 140 parts by mass of the total of the unsaturated polyester and the crosslinking agent. The filler comprises one or more fillers (filler A) selected from the group consisting of calcium carbonate, glass, silica, talc, clay, barium sulfate, calcium silicate, titanium oxide, and a hollow filler and one or more fillers (filler B) selected from the group consisting of aluminum hydroxide and alumina. The mass ratio of filler B to filler A is 1 or more. The unsaturated polyester resin composition of the present invention is optimal for producing a molding resin for use in a switched reluctance motor, the molding resin barely causing void formation upon sealing, effectively preventing vibration of stator salient poles, and barely generating cracks when vibration and heat are generated during motor operation.

The present invention provides antifouling coating compositions having excellent long-term storage stability and provides an antifouling coating composition that can maintain the stable dissolution and antifouling performance of a coating film without causing coating film defects such as cracks in seawater for a long term, such that an antifouling coating film having increased environmental safety can be formed. The present invention provides an antifouling coating composition containing: (A) a triorganosilyl ester-containing copolymer obtained from a mixture of (a) a triorganosilyl (meth)acrylate monomer represented by general formula (1): (here, R 1 is a hydrogen atom or a methyl group; and R 2 , R 3 , and R 4 are the same or different from each other and each represents a C 3-6 alkyl group branched at the ±-position or a phenyl group) and (b) an ethylenically unsaturated monomer copolymerizable with the triorganosilyl (meth)acrylate monomer; and (B) calcium sulfate hydrate.

Provided in the present invention are the biodegradable polymer master batch having good dispersion effect and excellent interface bonding property, and the preparation method thereof.
摘要:
A polymeric carrier composition including a polymer synthesized from monomers selected from acrylic acids, methylacrylates and urethanes and at least one metal having an oxidation state of +1 or +2, including salts and coordination complexes thereof. The composition may be a suspension having 0.5 to 10% by weight of the polymer prepared from monomers selected from a group consisting of acrylic acids, methylacrylates and urethanes, and a viscosity less than 1,000 cps. The composition is applied to substrates, such as woven fabrics, to create metal-infused articles.
