Abstract: One-part room-temperature curable compositions (RTV-1 compositions) based on organosilicon compounds are less toxic compared to conventional compositions containing organotin compounds and, at the same time, have excellent curing properties, a skin formation time which allows proper handling and tooling, and excellent storage stability. The compositions contain: at least one organosilicon compound containing condensable groups; at least one curing agent having the formula R′Si(OOCR″)3, wherein R′ is C3-C6 alkyl, and R″ is C1-C6 alkyl; at least one organotitanium compound curing catalyst; and at least one filler.

Abstract: Moisture curable RTV-1 compositions with rapid curing and a modulus which is adjustable over a wide range include organopolysiloxanes having on-chain and side-chain silicon-bonded α-aminoalkyl groups and at least on average two silicon-bonded alkoxy groups, trialkoxyorganylsilanes and/or tetraalkoxysilanes, and organopolysiloxanes bearing alkoxysilyl groups.

Abstract: One-part room-temperature curable compositions (RTV-1 compositions) based on organosilicon compounds have improved storage stability and excellent physical properties, and contain (A) at least one organosilicon compound containing condensable groups, (B) at least one curing agent comprising a combination of n-propyltriacetoxysilane and methyltriacetoxysilane, and (C) at least one curing catalyst comprising an organotin compound. The curing agent is a combination of n-propyltriacetoxysilane and methyltriacetoxysilane reduces the tendency of the composition to crystallize without impairing the chemical and physical properties of the composition.

Abstract: Moisture curable elastomer compositions are highly suitable for use as sealants, and initially contain an organopolysiloxane having condensable groups, a tri-acyloxy functional organosilicon compound, and as fillers, anhydrite and silica. The compositions have very low modulus and accommodate high joint movement, while being storage stable
