Abstract
In an RTV organopolysiloxane composition comprising a hydroxy-terminated diorganopolysiloxane and an organic silicon compound having at least three hydrolyzable groups, there is blended calcium carbonate which has been treated with 1-2.5% by weight of an agent having a melting or softening point of at least 100.degree. C. or a saturated fatty acid having at least 21 carbon atoms. The composition is adhesive to even surface treated aluminum plates and maintain a firm bond under water immersion and at elevated temperatures.
