Silicone grease is widely used as a temporary sealant and a lubricant for interconnecting ground glass joints, as is typically used in laboratory glassware.Although silicones are normally assumed to be chemically inert, several historically significant compounds have resulted from unintended reactions with silicones.
Sugru (/ ˈ s uː ɡ r uː / [1]), also known as Formerol, is a patented [2] multi-purpose, non-slumping brand of adhesive silicone rubber that resembles modelling clay. [3] It is available in several colours and upon exposure to air, cures to a rubber-like texture.
Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
The rubbery, vinegary-smelling silicone caulks, adhesives, and aquarium sealants are also well-known. PDMS is also used as a component in silicone grease and other silicone based lubricants, as well as in defoaming agents, mold release agents, damping fluids, heat transfer fluids, polishes, cosmetics, hair conditioners and other applications.
One use for methyltrichlorosilane is in the production of methyl silicone resins (highly crosslinked polymers). Because of the stability of the cross-linked polymers resulting from condensation, the resin is stable to 550 °C in a vacuum, making it an ideal material for electrical insulation at high temperatures.

APTES is a toxic compound with an MSDS health hazard score of 3. APTES fumes are destructive to the mucous membranes and the upper respiratory tract, and should be used in a fume hood with gloves. If a fume hood is not available, a face shield and full face respirator must be implemented.
Typically the sealant products manufactured with silyl-modified polymers have good adhesion on a wide range of substrate materials, and have good temperature and UV resistance. MS polymers consist of a polyether backbone with dimethoxy-silyl or trimethoxy-silyl ends, with trimethoxy-silyl groups being more reactive.
Silastic-brand silicone elastomers have a range of applications. In the automotive industry they are used for making gaskets, spark plug boots, hoses and other components that must operate over a broad temperature range and resist oil and coolants.
