A one or more component moisture cure Organosiloxane composition that has strength in an uncured state (commonly referred to in the industry as 'green strength') and its uses. The composition comprises an organopolysiloxane polymer having a viscosity of at least 1000 mPa&#xb7;s at 25&#xb0; C. and not less than two silicon-bonded hydroxyl groups and/or silicon bonded hydrolysable groups; a suitable catalyst; a cross-linker adapted to react with organopolysiloxane polymer when catalysed with the catalyst; and optionally one or more rheology modifiers and 0 to 10% by weight of the composition of one or more extenders or plasticisers but in particular the composition contains a precipitated calcium carbonate filler in an amount of from 50 to 70 weight % of the total composition.
