Patent ID: 8183307

Claim:
A crosslinkable viscous to pasty composition based on organosilicon compounds which can be crosslinked by a condensation reaction, comprising: (A) at least one organosilicon compound with at least two condensable groups, (B) at least one encapsulated biocide, (C) optionally, one or more crosslinking agents, and (D) compounds bearing basic nitrogen, wherein at least one biocide of component (B) is 2-(n-octyl)-4-isothiazolin-3-one (OIT) or 4,5-dichloro-2-(n-octyl)-4-isothiazolin-3-one (DCOIT), the biocide(s) being present in the encapsulated biocide in an amount of from 40% to 80% by weight based on the weight of the encapsulated biocide, wherein after storage of four months, the composition has not yellowed as determined by visual observation.
