Abstract: Compositions which are crosslinkable contain an alkoxysilyl or hydroxyl-functional binder and functionalized particles prepared by reacting a filler having reactive groups on its surface with an alkoxysilane in which an alkoxysilyl group is linked to a heteroatom by an optionally substituted methylene spacer. The particle may react with the alkoxy group of the alkoxysilane or with a group containing the heteroatom of the alkoxysilane to functionalize the particles.

Abstract: Coating compositions exhibiting improved reproducibility and improved scratch resistance contain an ethylenically unsaturated binder and filler particles functionalized with an ethylenically unsaturated group-containing monoalkoxy silane.

Abstract: Alkoxysilyl-terminated preopolymers prepared by reacting an alkoxysilane with a prepolymer prepared by reacting a di- or polyisocyanate with both a low molecular weight diol or polyol and a high molecular weight polyol, the respective polyol components present within a specific ratio range, and giving rise to an increased content of urethane groups, and an inhomogenous distribution thereof exhibit high tensile strength and elongation, even without the use of fillers.

Abstract: One-component, moisture curing compositions which exhibit rapid curing, even with exceptionally low levels of catalyst or with no catalyst at all, can be formulated from alkoxysilane-terminated polymers having alkoxysilane groups bonded to an electronegative, free electron-pair-containing heteroatom via a methylene linking group. Polymer blends containing the alkoxysilane-terminated polymers exhibit rapid cure, even at room temperature, and allow the use of nitrogen containing components such as adhesion promoters.

Abstract: Foamable mixtures of excellent quality and which are isocyanate free are prepared from silane-terminated prepolymers in which a proportion of the silane end groups are replaced by non-polar organic groups. As a result, the prepolymers have much greater hydrocarbon blowing agent compatability.

Abstract: Alkoxy-crosslinking one-component moisture curing compositions contain a polymer bearing (alkoxy)(methyl)silylalkyl-terminal groups, and specific silanes as described herein. The compositions exhibit improved shelf life and yet retain other desirable characteristics.

Abstract: Foamable compositions which are free of isocyanates, which exhibit low shrinkage, low propensity toward crack formation, and which display good flammability resistance, are prepared from blowing agent-containing compositions of alkoxysilane-terminated prepolymers derived from a polyol component which contains one or more halogenated polyols.

Abstract: Curable, silane-terminated polydiorganosiloxane-urethane copolymers exhibit the beneficial properties of isocyanate-terminated polysiloxane-urethane copolymers without the detriments associated with free isocyanate groups.

Abstract: Condensation curable systems employ ordinarily highly reactive polymers bearing methylene-linked alkoxysilyl groups. By limiting the amounts of activating compounds during the preparation of such polymers, the reactivity is sharply decreased, yet can be increased by addition of suitable catalysts. As a result, the polymers may be easily processed, yet the moisture curing times may be adjusted readily.

Abstract: Foamable compositions which are preferably isocyanate-free and which exhibit good foaming properties including short application times and freedom from cracks in the cured foam, are obtained from alkoxysilane-terminated prepolymers preferably containing polyurethane moieties, a blowing agent component, and a solvent having a boiling point in excess of 30° C.
