Moisture-activated adhesive compositions are provided which comprise the reaction product of (a) a polyisocyanate and (b) an isocyanate-reactive component comprising an aliphatic tertiary amine-initiated polyol having an ethylene oxide content of at least 1%. Methods for bonding substrates with the present adhesive compositions are also disclosed.

Moisture-activated adhesive compositions

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

A process is disclosed for strengthening and sizing paper which comprises the step of applying a composition comprising (a) an isocyanate and (b) an isocyanate-reactive component comprising at least one polyol having an ethylene oxide content of at least 1%, wherein said composition does not contain water to the paper by means of an electrostatic spraying device having a linear orifice.

Process for treating and sizing paper substrates

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.

A self-release binder system comprising (a) an organic polyisocyanate binder; and (b) a composition comprising (i) a wax and (ii) a fatty acid.

Bowling ball having improved surface slip

Polyurethane, polyurea and polyureaurethane resins having improved mold release properties are made by including with the reactive ingredients certain internal mold release agents which are polysiloxane polymers having pendant organic groups which contain at least one hydroxyl, amino or mercapto group.

Process for forming mold releasable polyurethane, polyurea and

Cellulosic papers having improved handling and strength properties result when made by using as an internal or surface sizing an aromatic polyisocyanate/isocyanate terminated prepolymer blend.

Paper products sized with polyisocyanate blends

Blends of polyols and polyamines containing internal mold release agents consisting of certain polysiloxanes having pendant organic groups which have functional hydroxyl, amino or mercapto groups are useful in preparing mold releasable resin moldings when made by the reaction injection molding technique.

Polyamines and polyols containing a polysiloxane internal mold release

The invention is directed to a liquid polyisocyanate dispersions containing an unreacted polysiloxane mold release agent which has isocyanate reactive groups. Specifically, the invention is directed to polyol modified diphenylmethane diisocyanates having dispersed therein a polysiloxane compound having pendant organic chains which contain at least one hydroxyl, amino or carboxyl functional group and a silicone dispersing or inhibiting agent substantially free of isocyanate reactive groups.

Stable dispersions of polyisocyanates containing polysiloxane mold

Blends of silicone surfactants substantially free of isocyanate reactivity and certain polysiloxane compounds having pendant organic chains which have at least one isocyanate reactive functional group are useful as internal mold release agents. These blends form stable dispersions in liquid polyisocyanates for use in reaction injection molding techniques.
