Abstract: A one-part moisture-curing liquid-applied waterproofing membrane is disclosed as including a polyurethane polymer and two different aldimines as blocked amine hardeners in a specific ratio range. The membrane has a low odor, a long shelf life stability, a low viscosity at low solvent content, a sufficiently long open time to allow hand application and cures fast to a solid elastic material. The liquid-applied waterproofing membrane is particularly suitable for roofing applications, possessing high strength, high elongation and good durability under outdoor weathering conditions in a broad temperature range.

Abstract: A multi-component composition contains a) a polyol component having a1) acrylate polyol and a2) at least one of polyester polyol and polyether polyol, wherein the equivalent ratio of hydroxyl groups of acrylate polyol to hydroxyl groups of the at least one of polyester polyol and polyether polyol is in the range of 0.4 to 3.8, and b) an isocyanate component containing b1) aliphatic polyisocyanate monomer, dimer and/or trimer, and b2) aliphatic polyisocyanate prepolymer, wherein the equivalent ratio of isocyanate groups of aliphatic polyisocyanate monomer, dimer and/or trimer to isocyanate groups of aliphatic polyisocyanate prepolymer is in the range of 0.5 to 2.6. The multi-component composition is suitable for use as a top coat on elastic membranes, in particular roofing membranes, to provide sufficient weathering resistance/protection.

Abstract: The present invention describes a one-part moisture-curing liquid-applied waterproofing membrane including a polyurethane polymer and both an aldimine and an oxazolidine as blocked amine hardeners in a specific ratio range. The membrane has a low odor, a long shelf life stability, a low viscosity at low solvent content, a sufficiently long open time to allow hand application and cures fast to a solid elastic material. The liquid-applied waterproofing membrane can be suitable for roofing applications, possessing high strength, high elongation and good durability under outdoor weathering conditions in a broad temperature range.

Abstract: A coating composition including at least one water-based anionic polyurethane dispersion and 0.1 to 4 weight-% of nanoparticulate TiO2 having an average particle size of not more than 100 nm, based on the solids content of the coating composition. The cured coating composition is suitable as a top coat in a decorative multilayer coating system including at least one polyurethane base coat. The multilayer coating system exhibits improved non-yellowing property and cleanability. The liquid multilayer coating system is particularly suitable for balcony applications.

Abstract: A one-part moisture-curing liquid-applied waterproofing membrane as disclosed includes a polyurethane polymer obtained from at least one polyether polyol and at least one diisocyanate, and an aldimine of the formula (I). The membrane has a long shelf life stability with both aromatic and aliphatic isocyanates, a low viscosity at low solvent content, a sufficiently long open time to allow hand application and cures fast to a solid elastic material of high strength and high elongation. The released aldehyde is non-toxic and low flammable and evaporates quickly out of the membrane causing only minimal odor emission. The membrane has high crack-bridging qualities in a broad temperature range and is easily overcoatable without interlayer adhesion problems, which makes it particularly suitable for roofing applications.

Abstract: The present application is directed at the reaction product of an azide compound having two or more azide groups attached thereto and an alkyne compound having two or more alkyne groups attached thereto, wherein the azide and alkyne groups react in a 1,3-dipolar cyclo addition to form 1,4-disubstituted triazols and wherein the azide or alkyne compound or both include —O—(C═O)—NR— functional groups. The reaction products can be used as coatings, such as for flat roofs, sealants, adhesives and in elastomer applications. Methods for producing the reaction products as well as substrates including a coating of the reaction product are also disclosed.
