RTV Silicone Sealant

Applications for silicone sealants are extremely broad. Markets include construction, automotive, assembly, maintenance, electrical/electronic, aerospace, and consumer products. Silicone sealants often compete with other materials such as polyurethanes, polysulfides, and acrylics. One of the most popular subclasses of silicone sealants is the RTV (room temperature vulcanizing) product. RTV silicone products are formulated from relatively low molecular weight linear polymers. A crosslinking

reaction begins at the time the product is exposed to air. These crosslinking reactions occur at room temperature, hence the term “RTV”, and they are generally moisture-curing reactions. Among three types of RTV sealants classified by the curing mechanisms, TiTAS titanates crucially catalyze alkoxy type crosslinking reactions.

Moisture scavenging property contributed by TiTAS titanates is an additional benefit extending shelf life of the sealant cartridges.

Though the alkoxy type RTV sealant being invented 30 years ago, the formulation is not changed too much even today. TiTAS titanates continuously provide the highest liability to the harshest application field, such as glass wall architectures.

Advantages of TiTAS Titanates

TiTAS titanates provide superior catalysis performance, ie. quick tack free time, as well as adhesion promotion and crosslinking properties. Though condensation catalysts such as tin compounds can do the same, TiTAS titanates offer the non-toxic and reliable features than others.

Application Field

TiTAS PS ranges are readily applicable for RTV sealant formulators fitting into the consumer or industry usage. Furthermore, TiTAS primaries, such as TPT, PS8 or PS10 offer high purity, superior reliability and extraordinary stability for high end usage.
