Abstract:
The present invention is an adhesive composition for stabilizing an electrical conductor. The adhesive composition includes a base polymer and an additive for absorbing UV light, such as a benzotriazole or a benzophenone. When the adhesive composition is in contact with the electrical conductor, the electrical conductor has less than about a 20% change in electrical resistance over a period of about 500 hours.
Abstract:
A laminate body (1) of the present invention includes a base material (2), a film-like or a membrane-like undercoat layer (3 or 103) that is formed in at least a portion of the outer surface of the base material (2), and an atomic layer deposition film (4) that is formed on a surface opposite to a surface coming into contact with the base material (2) among both surfaces of the undercoat layer (3 or 103) in the thickness direction thereof. At least a portion of precursors of the atomic layer deposition film (4) bind to the undercoat layer (3 or 103), and the atomic layer deposition film (4) is formed into a membrane shape covering the undercoat layer (3 or 103).

Abstract:
In one aspect the invention is a composition comprising a prepolymer which is the reaction product of di(isocyanatophenyl) methane or a polymeric di(isocyanatophenyl) methane having an isocyanato functionality of about 2.1 to about 3.0 with a mixture of one or more diols and one or more triols wherein the ratio of isocyanate equivalents to hydroxyl equivalents in the reaction mixtures used to prepare the prepolymer is from about 1.2 to about 1.8 and the ratio of diol to triol where the diisocyanate is a di(isocyanatophenyl) methane in the reaction mixture is from about 5:1 to about 1:1. and where the isocyanate is a polymeric di(isocyanatophenyl) methane is from about 8:1 to about 4:1; wherein the prepolymer could further react with an isocyanate reactive monofunctional compound. The prepolymer herein has an isocyanate content of about 0.5 to about 1.5 percent by weight, a free isocyanate monomer content of about 1.0 percent by weight or less as measured by high pressure liquid chromatography. These prepolymers can be used in many applications including adhesive, sound dampening sealer and coating and especially in making adhesives or adhesive systems with a low content. of monomeric isocyanate to bond together similar or dissimilar substrates such as metal, glass, ceramics, plastic and painted steel panel.
