A composition for use as a binder for coating compositions containing a chlorine-containing polymer having a chlorine content of 40-75 weight percent and a number average molecular weight of 3500-40,000 and an acrylic star polymer and a low molecular weight plasticizer that is a chlorinated aliphatic hydrocarbon having a chlorine content of 20-70 weight percent or a monomeric or polymer ester having molecular weights of from 200-2500.
摘要:
A new lubricant comprises at least one compound having a perfluorocyclobutane group, preferably a perfluorovinyl aryl ether. The lubricant is conveniently applied from solvents which are not chlorofluorocarbons and is effective at high temperatures e.g., in engines and for magnetic media, either internally or topically.
摘要:
An ordinary temperature-curable resin composition comprising (A) a hydrolyzable silyl group-containing fluoroolefin copolymer obtained by polymerizing a monomeric mixture comprising a fluoroolefin as an essential component in the presence of a hydrolyzable silyl group-containing compound, (B) a curing catalyst, and (C) an organic solvent.
摘要:
The wet adhesion of plastics dispersions and of paints made therewith is widely improved, if in the manufacture of the dispersions a nucleophilically substitutable .alpha.-.beta.-unsaturated halogen compound in an amount of 0.5 to 10% by weight calculated on the total amount of monomers is copolymerized, and the dispersion so obtained is reacted with ammonia at a temperature of at least 50.degree. C.
摘要:
A laminate has at least two layers, at least one of which comprises a polymer having more than one perfluorocyclobutane group. Such polymers impart qualities of enviornmental or protection, chemical and solvent resistance, hydrolytic stability, lubricity, low dielectric, hydrostatic stability, weatherability, flame resistance, chemical resistance, hydrolytic stability, lubricity, environmental protection, scratch resistance, solvent resistance, surface passivation, water repellancy, lower surface refractive index, lower surface coefficient of friction, fluid barrier properties, oil repellancy, thermal stability, and/or reduced moisture pick-up. Additionally, the coatings are optically clear, easy to apply either neat, in a solvent or otherwise, have relatively low cure temperatures for their temperature resistance, and exhibit insulating and planarizing capabilities.
摘要:
A method of protecting machine-readable markings on the surfaces of articles consisting in applying to the machine-readable markings a thin layer of an amorphous fluoropolymer, which may be, i.a., a copolymer of perfluoro(1,3-dioxole) or of perfluoro(2,2-dimethyl-1,3-dioxole) with a fluoromonomer selected from a specifically recited group, especially, with tetrafluroethylene; or a cyclic aliphatic homopolymer in which the repeating unit contains an aliphatic ring of 5-9 members, at least two of the ring members being carbon atoms independently substituted either by fluorine atoms or by perfluoromethyl groups, at most two of the ring atoms being oxygen atoms, the remaining portions of the repeating units, when present, being pefluoromethylene groups.
