Silicone sealant having adjustable flow properties

A method for adjusting the flow properties of a one-component moisture-curable silicone composition, comprising adding up to 5 parts by weight of an organoalkoxysilane or organoalkoxysiloxane OS that contains at least two alkoxysilane groups to a one-component moisture-curable silicone composition comprising

• a) 100 parts by weight of at least one crosslinkable polydiorganosiloxane OH-PDMS having silanol end groups and a viscosity at 23° C. of 1000 to 350000 mPa·s, measured in accordance with DIN EN ISO 3219;
• b) 5 to 20 parts by weight of at least one hydrophilic silica KS;
• c) 1 to 10 parts by weight of at least one organoalkoxysilane or organoalkoxysiloxane crosslinker V that contains at least 2 alkoxysilane groups;
• d) 1 to 7 parts by weight of an organoalkoxysilane or organoalkoxysiloxane AS that contains at least one aminoalkyl group having a primary amino group;
• e) 0.1 to 7 parts by weight of at least one tin catalyst K;
• wherein the silicone composition contains less than 1.0% by weight of water based on the total composition, with the proviso that the reactivity in respect of hydrolysis of the organoalkoxysilane or organoalkoxysiloxane OS is greater than the reactivity in respect of hydrolysis of the organoalkoxysilane or organoalkoxysiloxane crosslinker V.
