  • Patent number: 4997861
    Abstract: An adhesive composition, of the `instant adhesive` type, comprising:(a) from 77 to 95% by weight of monomeric 2'-ethoxyethyl 2-cyanoacrylate;(b) from 3 to 15% by weight of a poly-(C.sub.1-5) alkyl acrylate or methacrylate having an average molecular weight within the range of from 400,000 to 600,000;(c) from 2 to 8% by weight of hydrophobic fumed silica; and(d) from 100 to 1000 ppm by weight of a polymerization stabilizer;overcomes a number of disadvantages associated with currently available `instant adhesives` (such as high volatility, brittle adhesive bond, poor resistance to heat and unpleasant smell) and it has the advantages that it cures rapidly and can be used on porous substrates.
    Type: Grant

  • Patent number: 4716189
    Abstract: A stick for the application of adhesive material to a substrate, comprising an adhesive dissolved or dispersed in a liquid medium containing an alkali metal or ammonium salt of an aliphatic carboxylic acid having from 8 to 36 carbon atoms, characterized in that the adhesive comprises a mixture of (i) an aqueous dispersion of an optionally carboxylated (C.sub.4 to C.sub.10)-alkyl ester of acrylic acid and (ii) an aqueous dispersion of polyethylene.The stick enables articles to be removably bonded to substrates without leaving a film of adhesive on the substrate after removal.

  • Patent number: 4467079
    Abstract: A curing composition consisting of two components, one of the components comprising a vinyl monomer and an initiator of polymerization, the other component comprising an accelerator of polymerization, characterized in that the composition further comprises a redox indicator having E.sub.o from above +0.01 to below +0.76 volts and R.sub.H from 13.5 to 28.

  • Patent number: 4292229
    Abstract: Synthetic rubber based adhesives comprising a solution of(a) a linear branched-chain polyurethane rubber,(b) a carboxylated butadiene-acrylonitrile rubber, containing at least 50% butadiene by weight, and(c) the reaction product of sorbitol and benzaldehyde in a non-aqueous solvent system and, optionally,(d) a non-aqueous solution of a phenolic resin, are form-retentive and are useful in glue-sticks.

  • Patent number: 4286890
    Abstract: A shaped article is produced which comprises a composite solid gel or waxy mass composed of a plurality of discrete solid gel or waxy regions having a common interface, each said region containing at least one reactive substance, the regions being so located in the shaped article that each region may be brought in contact with the desired substrate on which the reactants may be brought together and whereupon a reaction takes place.
