The disclosure relates to moisture curable compositions based on a combination of silane-modified polymer and silane functional additive, their manufacture and use. The silane functional additive is preferably prepared from a water miscible polyol having a functionality of about 2 to about 4 and/or a polyol having a tertiary nitrogen atom in the backbone and a functionality equal or greater than about 2.

Silane modified polymers with improved properties

Disclosed are silane modified copolymers that are moisture curable; curable adhesive compositions comprising the silane modified copolymers; and methods of making the silane modified copolymers.

Silane modified polymers with improved characteristics for adhesive compositions

Disclosed is a moisture curable silane modified terpolymer comprising a polyether segment, a segment of polytetrahydrofuran or polycarbonate, a polysiloxane segment and terminal amino silane groups joined to the terpolymer via urethane linkages and wherein the polyether segment comprises at least 70% by weight based on the total weight of the silane modified terpolymer. Also disclosed is a method of forming moisture curable silane modified terpolymer.

Silane modified polymers and use of the same in adhesive compositions

The present specification relates to moisture reactive hot melt adhesive compositions comprising a silane reactive plasticizer and the reaction product of (i) a semi-crystalline polyol and (ii) a polyisocyanate and (iii) an aminosilane; the production of such adhesives; and the use of such adhesives.

Reactive hot melt adhesives with improved adhesion

The present disclosure relates to silane reactive hot melt adhesive compositions including acid functional wax and basic functional wax; the production of such adhesives; and the use of such adhesives. The silane reactive hot melt adhesive compositions have improved green strength as compared to silane reactive hot melt adhesive compositions without the acid functional wax and basic functional wax.

Reactive hot melt adhesive

The present invention relates to silane reactive hot melt adhesive compositions having improved green strength, the production of such adhesives and the use of such adhesives.

High green strength reactive hot melt adhesives are prepared using silane-functional liquid polymers. The adhesive are formulated using a silane-reactive polymer or, alternatively, a non-silane-reactive polymer together with a compatible tackifier.

The present invention relates to new improved adhesives for binding books and related articles and the production of such adhesives. In particular, the adhesives have reduced content of monomeric diisocyanates or no monomeric diisocyanate content.

Moisture cure hot melt adhesives

Pressure sensitive adhesive formulations of an acrylic polymer grafted with a macromer are particularly well suited for use in the manufacture of impact resistant articles such as impact resistant glass laminates and products comprising such laminates.

Acrylic pressure sensitive adhesive formulation and articles comprising same

Articles prepared with a pressure sensitive adhesive prepared by combining an acrylic polymer and a silane-functional polymer, such as glass and plastic laminates, show improved impact resistance.

Pressure sensitive adhesive compositions and articles prepared using such compositions

A two component polyurethane adhesive composition having one or more polyols as a first component and one or more isocyanates as a second component. The composition also comprises one or more catalysts and one or more blocking agents to delay the curing reaction. The composition provides long open time, improved wet out of the substrates to be bonded, a rapid cure rate and excellent final bond performance at room and elevated temperatures. Optional ingredients, such as fillers, chain extenders and plasticizers may be added as desired. In one embodiment, the catalyst is a tin catalyst such as dibutyl tin dilaurate which may optionally be combined with other catalysts such as tertiary amines. The blocking agent in one embodiment is 8-hydroxyquinoline.
