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.

Sustained release air freshening device

UV curable, liquid, oligomeric compositions are prepared from the reaction product of a Michael addition oligomer and an isocyanate capped polybutadiene. The UV curable, liquid, oligomeric compositions can be cured in the presence of fragrances to form articles that are characterized by a controlled release of the fragrance over time.

Liquid oligomeric compositions containing acrylate unsaturation and polybutadiene segments

The subject invention relates to a foundry binder system which cures in the presence of a volatile amine curing catalyst comprising (a) an epoxy resin, (b) an acrylated organic polyisocyanate, (c) a reactive unsaturated acrylic monomer, acrylic polymer, or mixtures thereof, and (d) an oxidizing agent comprising a hydroperoxide. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes which are used to make metal castings.

Foundry binder of epoxy resin, acrylated polyisocyanate and acrylic

The subject invention relates to a foundry binder system that cures in the presence of a volatile amine curing catalyst. The binder system comprises a Part I component comprising (1) a phenolic resin component, and (2) a free radical initiator, and a Part II component comprising (1) a polyisocyanate, and (2) a multifunctional acrylate. 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.

Acrylic-modified phenolic-urethane foundry binders

The subject invention relates to a foundry binder system that cures in the presence of a volatile amine curing catalyst. 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.
