Moisture curable elastomer compositions are highly suitable for use as sealants, and initially contain an organopolysiloxane having condensable groups, a tri-acyloxy functional organosilicon compound, and as fillers, anhydrite and silica. The compositions have very low modulus and accommodate high joint movement, while being storage stable
