About WACKER Silicone Adhesive Sealants
Also available to buy online at 
Cost-effectiveness and sustainability are key considerations when it comes to bonding and sealing. Bonding with silicone adhesive sealants has decisive advantages over traditional mechanical joining technologies in terms of handling, functionality, durability and cost-efficiency. Single part RTV (RTV-1) silicones are one-step, ready-to-use adhesives and sealants. They crosslink automatically when exposed to air humidity at room temperature. These silicone rubbers are either room-temperature-vulcanizing (RTV) or one-part heat-curing systems. Both systems are exceptional for their processing properties.
Another important criterion for selecting the best product is the flow property – we offer you RTV-1 silicones with a consistency ranging from free-flowing to non-sag pastes.
WACKER silicone adhesive sealants can be applied easily and economically either manually or with automated dispensing equipment. Compared to mechanical joining methods, adhesive sealants significantly reduce not only the quantity of parts (e.g. screws, rivets, etc.) but also the number of process steps. Hence, silicone adhesive sealants help to reduce process cycle time.
RTV-1 silicones find many applications in form-in-place (FIP) gaskets and cure-in-place (CIP) gaskets.
