1. A moisture-curing composition comprising
a) at least one moisture-reactive polymer P in a proportion of 10% to 60% by weight, based on the total composition,
b) at least one inorganic filler F in a proportion of at least 9% by weight, based on the total composition, and
c) between 3% and 25% by weight, based on the total composition, of at least one type of hollow microsphere H,
wherein:
the composition has a density of less than 1.20 kg/L, and
the hollow microspheres H have:
a compressive strength, measured in accordance with ASTM D3102-72, of at least 2.5 MPa, and
a volume-based particle size D90, measured with a Coulter counter, of less than 100 μm.
