Abstract: This invention relates to a device that provides controlled release of a fragrant or deodorizing substance: the fragrant or deodorizing substance being solubilized with an appropriate carrier solvent within a polymeric matrix. The layers function as protective barriers, semi-permeable membranes, fragrance reservoirs, and adhesives. The device is capable of delivering a fragrance at a controlled rate for a prolonged period of time through the gradual diffusion and release of fragrant material carried by a solvent from a reservoir system to the semi-permeable UV curable, oligomer composition acting a fragrance release regulator. Additionally, the UV curable, oligomeric composition that forms the reservoir and regulating layer can be engineered to be adhesive through cure inhibition. The method of cure inhibition can also be utilized to create internal areas of high and low cross link density to further control the release rate of a fragrance.

The binder system comprises (a) a compound containing at least two active methylene hydrogen atoms, (b) an organic polyisocyanate (c) a reactive unsaturated acrylic monomer and/or polymer, (d) an oxidizing agent, and preferably (e) an epoxy component. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes that are used to make metal castings.

Abstract: An solvent-based pressure sensitive adhesive (PSA) having improved shear adhesion is composed of an acrylic-based PSA resin, an ethylenically unsaturated polyester, an ultraviolet radiation (UV) photosensitizer, and fugative organic solvent for the acrylic-based PSA resin. The PSA is cured by evaporation of the fugative organic solvent coupled with heat and UV irradiation or UV irradiation alone. Such PSA has improved shear adhesion by dint of the addition of the ethylenically-unsaturated polyester and an ultraviolet radiation (UV) photosensitizer. A method for adhering two substrates using the PSA includes applying the PSA to one or both of substrates. The solvent in the PSA is evaporated from the applied PSA. Finally, the polyester component of the applied PSA is cured by exposure of the applied PSA to ultraviolet (UV) radiation.
