A moisture-curable composition, including at least one organic polymer P containing reactive silane groups, between 1.0 wt.-% and 25.0 wt.-%, preferably between 2.0 wt.-% and 20 wt.-%, in particular between 2.5 wt.-% and 10 wt.-%, based on the total composition, of dimethyl or diethyl esters of aliphatic C3 to C5 dicarboxylic acids, and at least one curing catalyst for alkoxysilane groups. The moisture-curable composition is particularly suitable as elastic adhesive, coating, filler, or sealant and shows superior overpaintability, in particular with automotive topcoats or similar paints.

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.

Provided is a moisture curable polyurethane composition that is a moisture curable polyurethane having an isocyanate group on one end of a molecule thereof. The moisture curable polyurethane composition contains a moisture curable polyurethane (A) and an organic solvent (B).

Disclosed herein is a method of manufacturing a headlining, using a moisture-curing adhesive that can be molded at a relatively low temperature and enables energy saving by not requiring a condition in which bonding surfaces are preheated to an excessively high temperature. A headlining manufactured thereby the same method is also disclosed. The method includes coating a fabric with a moisture-curing adhesive, curing the moisture-curing adhesive by spraying water onto the moisture-curing adhesive, forming a headlining member by putting the fabric coated with the moisture-curing adhesive on a substrate after the curing, and pressing the headlining member so that the fabric and the substrate are bonded to each other and the headlining is shaped at the same time, after the forming.
