  • Patent number: 5143594
    Abstract: An asphalt or asphaltene refinery anti-foulant technique comprising the use in crude oil, or crude oil fraction, streams of alkyl-substituted phenol formaldehyde liquid resins in combination with hydrophilic-lipophilic vinylic polymers. The polymeric anti-foulant is added to asphalt or asphaltene containing crude oil streams to prevent fouling of metallic, or other, i.e. ceramic, surfaces, especially heat transfer surfaces.

  • Patent number: 5109052
    Abstract: A novel thermoplastic resin composition is disclosed, which comprises a polyphenylene ether, a polyamide and a specific block copolymer as main components and has a specific dispersion morphology such that the polyamide forms a continuous phase in which the polyphenylene ether is dispersed and the block copolymer is micro-dispersed in the dispersed phase of the polyphenylene ether. The composition of the present invention has an excellent balance of thermal stability, heat distortion resistance, impact resistance, oil resistance, stiffness, etc., and, hence, is useful as an engineering material in the fields of automobiles, electric and electronic industries.

  • Patent number: 4600728
    Abstract: Elastomer compositions are provided which contain high molecular weight water-insoluble humic acid humates. The compositions show improved bloom resistance in both the uncured and the vulcanized or otherwise cured state. Methods to make sponge rubber are also disclosed in which the humic acid humate is the gas producing agent. A predominantly humic acid humate containing composition maintains a clean mold, and curing an uncured article coated with the humate at elevated temperature will clean metal molds which have dirty surfaces, particularly when green coated articles are vulcanized in contact with the mold's surfaces.

  • Patent number: 4594384
    Abstract: The present invention relates to an adhesive composition for manufacturing glued laminated beams and wood constructions. One component of the adhesive composition is resorcinol-phenol resin. Resorcinol-phenol adhesives are as such known in the prior art. The main ingredients of these adhesives are resorcinol, formaldehyde and phenol. Among the drawbacks in the use and production of resorcinol-phenol adhesives are their high price and the fact that the raw materials are difficult to obtain. The purpose for employing the adhesive composition of the invention is to eliminate some of the difficulties connected with the availability of the raw materials, particularly resorcinol, and to help produce a new, more economical resorcinol-phenol based adhesive composition.

  • Patent number: 4526911
    Abstract: This invention relates to an improved coating composition for application to aluminum cell cathodes, wherein said composition comprises a Refractory Hard Material, and a thermosetting resinous binder system.The resinous binder system is characterized by a char yield greater than 25 percent, while the coating composition exhibits expansion characteristics such as to adhere to a cathode block at temperatures up to and including those normally encountered in the operation of an aluminum cell. The ablation rate of the carbon system utilized is essentially equal to the combined wear and dissolution rate of the Refractory Hard Material in an aluminum cell environment.

  • Patent number: 4521555
    Abstract: Plastisols useful for automobile undercoatings, anti-noise compositions, adhesives, sealing compositions and coatings for untreated, pretreated, phosphated, primed and prelacquered metal bases are improved by the addition of coke dust and coal dust fillers. The carbon dust fillers have a particle size of about 0.5 to 1000 microns and they are used in a concentration of about 9 to 90% by weight based on the total weight of plastisol and carbon dust. The carbon dust filled plastisols have a specific gravity of about 1.1 to 1.3.
