摘要:
The invention relates to a coating composition for preparing a back coating film of a mirror. This mirror serving as an anticorrosive mirror has a glass substrate, a silver mirror film that comprises silver and is formed on a back surface of the glass substrate, a metallic protective film that comprises a first metal and is formed on the silver mirror film, and the back coating film formed on the metallic protective film. The coating composition is substantially free of a lead component and comprises (a) a vehicle containing a synthetic resin, (b) a first salt formed by a neutralization of an acid with a base containing a second metal having an ionization tendency that is greater than the silver and the first metal, and (c) a basic compound selected from the group consisting of azoles and diamines. The acid is one compound selected from the group consisting of organic acids each containing an azole ring and unsubstituted and substituted carbamic acids. The mirror has advantageous characteristics, in mechanical processability and chemical and mechanical durabilities, which are comparable to those of a mirror having a back coating film containing a lead pigment.

Substituted 1,4,2-oxathiazines and their mono- and di-oxides, disclosed in WO-A-9505739, are used as additive to increase the self-polishing properties of antifouling paints. The additive is used in an amount of 0.5 to 9.9 wt. %, based on the total weight of the dry mass of the composition, preferably 1 to 8 wt. %, most preferably 2 to 4 wt. %. The preferred additive is 3-(3,4-dichlorophenyl)-5,6-dihydro-1,4,2-oxathiazine dioxide.
摘要:
A range of extruded polymers incorporating synthetic furanones was manufactured and field tested. Polymers incorporating furanones showed excellent antifouling efficacy and significantly reduced fouling for more than 100 days. The present inventors have developed polymers that release commercial short-lived biocides or analogues of antifouling compounds isolated from marine algae. A range of polymers incorporating either the commercial isothiazolone Sea-Nine 211™ or a halogenated furanone were effective antifouling treatments in laboratory and field trials. The efficacy of the polymers was dependant on polymer type and the initial concentration of the antifouling compound. The polymers can be extruded as filaments that can be woven into netting or extruded or molding for other applications. It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.

Crystalline modification of mixtures comprising (a) a nickel-quencher corresponding to [2,2′-thio-bis(4-t-octylphenolate)-n-butylamine Nickel (II)] and (b) a 2-hydroxy-4-alkyloxybenzophenone corresponding to 2-hydroxy-4-n-octyloxybenzophenone wherein it has two diffraction lines at angles 2{acute over (ø)}=6.291 and 2{acute over (ø)}=6.888 in the X-Ray diffraction spectrum from powders. The said crystalline modification can be used as a light stabilizer for agricultural films based on polyolefins or polyolefinic copolymers.

The present invention relates to vulcanizable rubber mixes which, apart from the rubbers, contain O,O-bis-(alkyl)-dithiophosphoric acid polysulfides and primary and/or secondary amines, which are characterized in that they may be vulcanized without release of nitrosamines with a high crosslink density and a high proportion of short sulfur bridges.
摘要:
A microbe-inhibiting (MI) compound is incorporated into a biodegradable polymer composition, most preferably, a starch-based polymer, to inhibit microbial growth and to attenuate the biodegradation of the polymer composition. Such a composition is used to manufacture any of a number of articles, particularly those that come in contact with foods such as foam containers and fruit shock absorber nets as well as packing materials such as loose fill pellets.
摘要:
The present invention provides a chlorine-containing polymer vulcanizing composition with improved preservation stability. The present invention is a chlorine-containing polymer vulcanizing composition obtained by blending (a) a zeolite compound, (b) a vulcanizing agent, and (c) an optional organic vulcanization accelerator. The zeolite compound can be natural zeolite, an A-type, X-type, or Y-type synthetic zeolite, a sodalite, natural or synthetic mordenite, ZSM-5, or a metal substitution product thereof. The zeolite compound is preferably an activated zeolite compound. With respect to 100 parts by weight of chlorinated polyethylene, (a) preferably 0.5 to 30 parts by weight, more preferably 5 to 25 parts by weight, of the zeolite compound, (b) preferably 0.1 to 5 parts by weight, more preferably 0.5 to 3 parts by weight, of the vulcanizing agent, and (c) preferably 0.5 to 3 mol, more preferably 0.7 to 1.5 mol, of the vulcanization accelerator with respect to 1 mol of (b) the vulcanizing agent are blended.
摘要:
Colorants comprising a chromophore having two methine moieties attached to a benzodifuranone backbone, wherein said moieties optionally have at least one poly(oxyalkylene) chain, preferably at least two such chains attached thereto are provided. Such colorants exhibit excellent thermal stability, effective colorations, excellent low extraction rates, and effective lightfastness levels, particularly when incorporated within certain media and/or on the surface of certain substrates, particularly polyesters. The optional poly(oxyalkylene) chains also increase the solubility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and/or on diverse substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such colorants are provided as are methods for producing such inventive colorants.
