Abstract:
Strippable, primerless, radiation curable protective coatings for silver, nickel, brass and aluminum surfaces comprising(a) colloidal inorganic oxide particles of diameter less than 50 nanometers;(b) non-silyl polyethylenically unsaturated monomers and oligomers; and(c) catalytic amounts of suitable photo-initiators.The cured protective coatings are useful for shaped metal objects and for metal coated thermoplastic substrates.
Abstract:
This invention provide an adhesive tape by which adhesion to a metal spreader is not required and a cutting process is not necessary. The adhesive tape comprises an adhesive layer provided on at least one surface of metal sheet, said adhesive layer being semi-cured into a B-stage and comprised of: (a) a piperazinylethylaminocarbonyl-containing butadiene-acrylonitrile copolymer of the formula (I): ##STR1## wherein, k, m, and n are molar ratios and taking n as l, k is a number of 3-175, and m is a number of 0.3 to 93; and (b) a compound having at least two maleimide groups, the ratio of component (b) based on 100 parts by weight of component (a) being in a range of 10 to 900 parts by weight, and said adhesive layer being composed of at least two semi-cured layers having each a different status of semi-cure.
Abstract:
A metallic foil tape having a top surface and a bottom surface with an adhesive applied to at least one of the top surface or the bottom surface of the metallic foil tape and corrugations in the metallic foil tape providing for expansion of the corrugated metallic foil tape in a circular or semi-circular shape. The corrugated metallic foil tape is suitable to be applied to contoured or three-dimensional surfaces, and is particularly suitable for use in sealing or joining components of heat, ventilation, and air conditioning (HVAC) units.

Abstract:
Graft compositions, useful for tie-layer adhesives, are disclosed. The graft compositions comprise the reaction product of a live, grafted polyolefin and an olefin elastomer. The grafted polyolefin is first made by heating a polyolefin and an unsaturated monomer. Further reaction of the live, grafted polyolefin with an olefin elastomer provides the graft composition. Grafting efficiency is boosted dramatically by the presence of the olefin elastomer and use of the additional reaction step. The graft composition, when formulated into a tie-layer adhesive at low concentration, affords multilayer structures with good adhesion and high clarity.
Abstract:
To prevent the growth of aquatic animals and plants on the surfaces of underwater structures, the surfaces are covered with a protective adhesive sheet comprised of a copper-nickel alloy plate having a weight ratio of copper:nickel in the range of 100:0 to 80:20, a primer layer formed on the alloy plate, and a pressure-sensitive adhesive layer formed on the primer layer. Prior to applied the adhesive sheet, the surface to be protected is preferably cleaned and coated with a primer of the same composition as that of the primer layer of the adhesive sheet.
