  • Patent number: 4666524
    Abstract: Compositions which contain one or more aluminum complexes, which find use in coatings, films, paints, lacquers and varnishes, are formed by reacting the aluminum complex with a nonfunctional resin. The nonfunctional resins have neither carboxyl nor hydroxyl functionality, yet react rapidly to form films in conjunction with the aluminum complexes.

  • Patent number: 4606791
    Abstract: Improved sizing compositions for cellulosic products, e.g., paper, are provided by combining first and second composition components while at least the second component is finely divided into fine liquid or solid particles. Component combination in this manner serves to provide especially effective sizing compositions.The first component comprises a material which provides both ammonia and ammonium salt when combined with other materials in the composition. Such ammonia-ammonium salt-providing material comprises at least one material selected from the group consisting of ammonia, or a precursor thereof; ammonium salts, or a precursor thereof; a reaction product of urea and at least one selected Lewis acid; and mixtures of these materials.The second component comprises a saponified, partially saponified or unsaponified rosin that is modified with either an .alpha., .beta.-unsaturated aliphatic acid generally containing from about 3 to 10 carbon atoms, an anhydride of such acids, or mixtures thereof.

  • Patent number: 4571356
    Abstract: This invention covers a water soluble one-component fiberglass mat binder composition which comprises a urea-formaldehyde resin and polyvinyl acetate polymers and/or vinyl acrylic-polyvinyl acetate copolymers in the manufacture of asphalt shingles. The shingles of the invention are formed by the asphalt coating of a fiberglass mat in which the glass fiber mat has been coated with the binder composition and cured to bond the glass fibers together in the mat structure.

  • Patent number: 4544690
    Abstract: An aqueous rubberized coal tar emulsion composition especially suitable for coating and sealing bituminous substrates containing asphalt such as asphalt pavement and the like, the coal tar emulsion composition comprising a major portion of commercial coal tar emulsion and water admixed with a small amount of a carboxylated butadiene/styrene/acid copolymer latex having a particular particle size. The emulsion composition may additionally include a fine aggregate filler material such as sand. The coal tar emulsion composition according to the invention is of a thixotropic nature and has the ability to maintain the fine aggregate when added and mixed therein in a homogeneous-like suspension. The emulsion composition when spread on an asphalt surface exhibits a high degree of spreadability and provides a sealing coating that has a long life.

  • Patent number: 4514539
    Abstract: The present invention comprises a stain resistant flame retardant insulating composition that is stain resistant under conditions of natural aging, heat aging, or exposure to gases such as hydrogen sulfide or methane. The inventive insulating composition remains substantially white in color under elevated heating and combustion temperature conditions. The stain resistant electrical insulating composition of the present invention is also flame retardant and has a polymer system comprising ethylene-vinyl acetate copolymer and polyethylene. The composition also utilizes a vinyl silane component as a coupling agent, peroxide cross-linking agents, fillers, and a three part stabilizing system.

  • Patent number: 4481989
    Abstract: The apparatus for extracting a tree stump from the ground without the root has a frame including locating means for locating the frame in a predetermined central position on a tree stump. Shearing means oppositely disposed on the frame are pivotable toward each other to cut the tap root of the tree stump in a lateral direction at a predetermined distance below the ground level. The shearing means are pivotable by a first set of hydraulic cylinders and also receive additional movement from a thrust member that moves longitudinally with respect to the frame and engages the shearing members during such longitudinal movement. The thrust member also includes an annular cutter portion for cutting the lateral root of the tree stump substantially simultaneously as the shearing members cut the tap root. In one embodiment of the invention the cutter blades of the shearing members are placed next to each other in substantially continuous line to line contact after total shearing of the tap root of the tree stump.
