摘要:
A B-stageable dielectric composition for flow control during electronic package assembly is described. The B-stageable composition comprises a resin matrix and flow control agents. The B-stageable composition is particularly useful in laminating substrates for electronic devices and electronic components, where the flow property of the composition must be tightly controlled during the assembly.
摘要:
A coating composition having outstanding electrically conductive and electromagnetic radiation absorptive properties is disclosed with a water emulsion polymer binder. The binder is a blend of a first emulsion containing a conjugated diene as monomer or comonomer, and a second emulsion containing an acrylic, aliphatic or aromatic polyurethane, polyester urethane, polyester, epoxy, polyamide, polyimide, vinyl, fluoropolymer, or silicone polymer. An effective amount of electrically conductive and electromagnetic radiation absorptive particles is dispersed in the binder. The particles include a combination of graphite particles, carbon nanotubes and metal containing particles. An effective amount of water is also present.

摘要:
Blends comprising at least two aqueous nitrile resin latexes which differ in film forming characteristics and dry film properties are useful in many applications as protective coatings. These blends are particularly useful as corrosion resistant coatings for metal substrates.
摘要:
A printable release coating composition having a combination of properties of good release, good ink retention, good adhesion, good tack and no backsize splitting is prepared having three essential components; (1) vinylidene chloride-acrylonitrile copolymer, (2) a polymer selected from vinyl chloride-vinyl acetate-vinyl alcohol terpolymer, vinyl acetate-vinyl alcohol copolymer and solvent soluble copolyester, and (3) vinyl ester-alkyl maleate copolymer.
摘要:
An aqueous coating composition for electrical conductors in which the film-forming constituents are(A) an acrylic polymer of acrylonitrile or methacrylonitrile, an alkyl acrylate such as butyl acrylate, methacrylic acid or acrylic acid, and an alkoxymethylacrylamide such as N-(isobutoxymethyl) acrylamide, and(B) a phenol formaldehyde condensate; the composition is particularly useful for coating wires and other electrical conductors of aluminum, copper, aluminum alloys and the like.
摘要:
Acrylonitrile, an acrylic ester such as ethyl acrylate, n-propyl acrylate, n-butyl acrylate, isopropyl acrylate, n-hexyl acrylate and the like are copolymerized with a cross-linkable monomer, an unsaturated organic acid and a vinyl monomer in a one-step or two-step operation to prepare a water-dispersion varnish for electrodeposition which has excellent dispersion stability and gives a coated film having excellent scrape abrasion resistance and high cut-through temperature.
摘要:
A water base, hardenable coating composition is disclosed for use on the inner or air conducting surfaces of fibrous glass thermal insulation employed in heating, cooling, or ventilating conduits. The coating comprises plasticizers, fillers, and binder.
