  • Patent number: 5801128
    Abstract: A dry Non-Oil metalworking lubricant that can be applied by a hot melt application. This dry lubricant is completely water soluble, provides rust protection, cleans from surfaces with plain room temperature water, and is more environmentally safe than other lubricants. A polyethylene glycol of sufficiently high molecular weight to be solid at room temperature is combined with amines, rust inhibitors, and metalworking additives to produce a thin film that provides protection for the part and the tooling in a metalworking operation. This lubricant provides further benefits to the overall process such as; easy to clean, weld through capability, excellent paint system compatibility, and environmentally superior to other lubricants.

  • Patent number: 5209971
    Abstract: Pressure sensitive adhesive compositions comprise one or more poly(alpha-olefin) homopolymers, copolymers, terpolymers, and tetrapolymers derived from monomers containing 6 to 10 carbon atoms and photoactive crosslinking agents wherein radiation curing provides adhesive films having a superior balance of peel and shear adhesive properties and the pressure sensitive adhesive is useful in pressure sensitive adhesive tapes, in articles containing transfer adhesive films, and as the bonding material between supports in a laminated structure.

  • Patent number: 4645711
    Abstract: The pressure-sensitive adhesive layer of the novel tape, like that of Silver U.S. Pat. No. 3,922,464, comprises a copolymer of alkyl acrylate such as isooctyl acrylate and a small amount of emulsifier monomer. The novel tape differs from that of Silver by incorporating tackifier resin, thus better resisting lifting forces at elevated temperatures while also being cleanly removable.
