The present invention not only can be adhered to non-primers with difficult to adhere materials such as surface-treated aluminum, fluorine-coated steel sheets, and acrylic electrodeposited steel sheets, but also has high storage stability and excellent heat and water resistance adhesion. A room temperature curable organopolysiloxane composition for providing a cargo.n n n The composition of the present invention is (A) organopolysiloxane represented by the following formula (1), (B) (R 4 O) 4-a R 5 a Si (wherein R 4 is methyl, ethyl, propyl, butyl or vinyl Group, R 5 is a monovalent hydrocarbon group, a is 0 or 1), and (C) a calcium carbonate surface-treated with a carboxylic acid having a melting point of 100 ° C. or higher, and (D) a condensation catalyst Obtained.n n n n n n n n n n Wherein R 1 and R 2 are monovalent hydrocarbon groups, R 3 is a methyl group, ethyl group, propyl group, butyl group or vinyl group, m is a positive integer, d is 0 to 10, n is 0 or 1 |
