The current invention relates to a moisture-hardening composition that contains, in addition to a silane-functional polymer with end groups of formula (I), a reaction product that can be manufactured from an amino silane with primary amino groups and an alkene that is free of silane groups. The compositions are characterized by improved expandability with concurrent high reactivity, good adhesion characteristics, and high tear strength and are suited especially for use as elastic bonding substance or sealant.

Moisture-hardening compositions containing silane-functional polymers and aminosilane adducts

The invention relates to moisture-curable compositions that air provided with increased elasticity while having good mechanical properties and adhesion. Said compositions contain at least on silane-functional polymer A, at least one aminosilane AS2, and at least one &#x3b1;-functional organodialkoxysilane at an amount of 0.6 to 5.0 parts by weight relative to 100 parts by weight of polymer A. Also disclosed are the production and use of the inventive compositions, especially as a sealant and adhesive.

Moisture-curable composition featuring increased elasticity

Moisture-curing compositions include at least one silane-functional polymer P with at least two terminal groups of formula (I), at least one aminosilane AS and at least one (meth)acrylsilane or anhydriodosilane of formula (II). The compositions have improved adhesive properties and are especially suitable for use as adhesives, sealing materials or coatings, especially as elastic adhesive or sealing materials.

Moisture-curing compositions containing silane-functional polymers with good adhesive properties

The invention relates to an adhesive composition containing a special silane cross-linking polymer and fine-particle coated calcium carbonate and soot. 20 to 50 ml of fine-particle coated calcium carbonate and soot are provided for every 100 g of polymer, and the volume ratio of fine-particle coated calcium carbonate and soot is between 70:30 and 30:70. The inventive adhesive composition is characterized by having good mechanical properties, a high electrical volume resistance and a good applicability.

Adhesive filled with surface-treated chalk and soot

The invention relates to a wooden floor, consisting of a hardenable adhesive () which is painted onto a floor base () in a continuous layer, and covering elements () consisting of wood or a wood material that are joined to the adhesive in its entirety by their surface () to be glued. According to the invention, the adhesive layer () has a thickness of 0.5 to 5 mm and the combined tension and shear strength of the adhesive (), in its hardened state, is les than that of the floor base () and is at most 1.2 N/mm, in order to obtain a floor covering with excellent dimensional stability.

A one-component polyurethane composition is described that comprises a latent curing agent bonded to the prepolymer, from which curing agent aldehyde is liberated upon curing. Said aldehyde comprises two phenyl groups. By the specific design of the polyurethane composition, the application characteristics as well as the aging resistance of the cured polyurethane are improved.
