A composition that includes at least one silane-functional polymer P and 20 to 60% by weight of aluminum hydroxide or magnesium hydroxide or mixture thereof, is disclosed. The composition has a viscosity of 500 to 20,000 mPa&#xb7;s measured according to DIN 53018 at a temperature of 20&#xb0; C. The composition is suitable as a liquid membrane and has very good flammability properties, i.e., it is difficult to ignite and is self-extinguishing.

Liquid film based on silane-terminated polymers

The present invention relates to compositions based on silane-functional polymers that are suitable for the adhesive bonding, sealing and coating of porous substrates, more particularly of porous mineral substrates, and that even after water storage ensure effective adhesion of the composition to the substrate.

Composition featuring enhanced adhesion to porous substrates

A method for the production of a roadway structure, the method including: (i) applying a primer to a support structure; (ii) applying a plastic membrane to the support structure that is primed according to step (i); and then (iii) applying an adhesive composition that includes a) at least one solid epoxide resin, and b) at least one thermoplastic polymer that is solid at room temperature, and (iv) applying a bitumen-based support layer.

Roadway structure having improved adhesive properties

The invention relates to a primer composition comprising a compound A1 which contains isocyanate-reactive groups. In order to produce said compound A1, a polyisocyanate A that is provided with at least three isocyanate groups, at least one silane B of formula (I), and a crosslinking agent C comprising at least three isocyanate-reactive functional groups are used. Also disclosed is the use of the inventive primer composition as a primer for adhesives, sealing compounds, or floor coverings, especially one-component moisture-hardening polyurethane adhesives or polyurethane sealing compounds based on polyurethanes or polyurethane-silane hybrids. The inventive primer composition is characterized particularly by excellent adhesion to glass and glass ceramics as well as an extended open time.
