Abstract

A moisture-curable composition having flame retardant properties and to the use thereof as an adhesive, sealant or coating. The composition according to the invention contains at least one moisture-reactive polymer in a proportion of 10% to 50% by weight, at least one precipitated, surface-coated aluminum trihydrate in a proportion of 30% to 60% by weight and in preferred embodiments up to 25% by weight of at least one phosphorus-containing compound and up to 20% by weight of at least one carbon additive. The inventive moisture-curable composition has excellent flame retardant properties and after curing remains resistant for a long time at high heat levels.
