Foamed molded articles produced by reaction injection molding (RIM) are provided. The molded articles are formed by reaction of a polyisocyanate component with an isocyanate reactive component in a mold using a blowing agent. The molded articles are preferably composites formed in the presence of a fibrous reinforcing material. The foamed articles are characterized by relatively short minimum mold residence times, and can thereby be produced more economically than prior art composites. The foamed articles are further characterized by a reduction in physical defects, such as splits and voids.

Molded foam articles prepared with reduced mold residence time and improved quality

Cold curing polyisocyanate adhesive compositions suitable for use in the preparation of engineered lumber composites. Additionally provided are catalysts comprising tertiary amine alkoxylates that are reduced in or substantially free of isocyanate-reactive hydroxylic or amine hydrogen atoms. Further provided is a process for preparing composites articles using the adhesive compositions and composite articles prepared from the adhesive compositions. Composite articles prepared from the adhesive compositions have a substantially increased resistance to delamination.

Alternative moisture cure catalysts and cold curing polyisocyanate adhesives prepared therefrom

A process of identifying terms or sets of terms in target domains having functional relationships (roles) analogous to terms (contained in the query) selected from a source domain whereby queryrelevant but semantically distant (novel) analogies may be retrieved, corresponding to any user defined query. The process is capable of discovering deep functional analogies between terms in source and target domains, even where there is a misleading superficial matching of terms (i.e. same terms, with different meanings) between the query and the target domains. The process comprises the automated generation of abstract representations of source domain content, and application of the abstract representations of content to the efficient discovery of analogous objects in one or more semantically distant target domains. Said abstract representations of terms are preferably vectors in a high dimensionality space, encapsulating characteristic occurrence patterns of terms in the source domain.

Method for retrieving semantically distant analogies

Improved sealants and adhesives derived from polyisocyanates having aromatically linked -NCO groups are cured at ambient temperatures when combined with a curing agent comprising an imino- and enamino-functional compound. These two component resin systems may be employed in fabricating multi-substrate laminates, especially those comprising lignocellulosic and cellulosic materials, such as wood and paper.

Polyisocyanate adhesive and sealant systems

An internal mold release system is provided which comprises (a) a polysiloxane compound; and (b) an amine salt of a carboxylic acid.

Internal mold release compositions

A method the preparation of rigid foams by reacting an organic polyisocyanate with an isocyanate-reactive material in the presence of a blowing promoter characterised in that the isocyanate-reactive material comprises at least one isocyanate-reactive cyclic carbonate or isocyanate-reactive cyclic urea, the reaction being performed in the presence of an inert insoluble organic liquid which is present as the dispersed phase of an emulsion or a microemulsion, and in the presence of a metal salt catalyst.
