The invention relates to a composition comprising and to a process for preparing moisture-crosslinking polymers under catalysis by a metal-siloxane-silanol(ate) compound, and to the use of the composition in the CASE sector (coatings, adhesives, sealants and elastomers), especially in the field of adhesives and sealants.

To provide a urethane resin composition having properties suitable for forming a building insulation layer without adding a foam stabilizer in a urethane resin composition having at least quasi-incombustibility.

A urethane resin composition for forming a foam that constitutes a insulation material for a building, the foam having at least quasi-incombustibility in a heat-release test complying with ISO-5660, wherein said urethane resin composition is characterized by containing at least a polyisocyanate compound, an ester polyol compound, a trimerization catalyst, an additive, and a non-silicon surface adjuster, and by not containing a foam stabilizer, the additive having red phosphorus as an essential component and being combined with a phosphate-containing flame retardant and/or a chlorine-containing flame retardant.

There is provided herein a polyurethane foam-forming composition comprising a hydroxyl-functional phosphonate of the general formula (I): wherein R.sup.1-R.sup.4 are as described herein. There is also provided a polyurethane comprising the reaction product of the polyurethane foam-forming composition and a process of making a laminated polyurethane comprising laminating a textile to a polyurethane, preferably a polyurethane foam. ##STR00001##
