Siloxane: Functionalization Chemistry With Amazing Performance

Siloxane Chemistry: (Si-O-Si)n

Siloxanes are class of molecules with a backbone of alternating silicon atom (Si) and oxygen (O) atoms, each silicon atom can have a connecting hydrogen (H) or an organic group. Siloxanes are building blocks for silicone oligomeric or polymeric products which are used in many products.

Properties of the siloxanes and polymerized siloxane products (sometimes called silicone products) depends on the size of the Si-O backbone in the molecule and the chemical groups attached to its backbone.

Siloxane Application

Siloxane or oligomeric/polymeric compounds made with siloxane are found in soaps, detergents, deodorants, plastics, paints and coatings. In the coatings and paint field, concrete coatings, water-stop coatings, waterproof coatings employ siloxanes. Majority of plastics used in our office, home and cars use siloxane and polysiloxane materials in formulation.  The concentration of these siloxane compounds may be as low as 100 ppm, but it offers properties typically not achieved by other additives.

Near 100% siloxane compounds are found in oils, greases, gaskets and lubricants.

Siloxanes also finds applications in coating metals including internal engine components, motor components and bearings.

Reactive Siloxanes

Small reactive siloxanes can react with surfaces to render a chemically bonded slick surface for many applications. Applications include industrial and biological applications.

Siloxane Hazards

While most oligomeric and polymeric siloxanes do not posed significant hazard to humans or animals as these materials have low bioaccumulation. Small molecule siloxanes like cyclic volatile melthyl siloxanes (cVMS) and decamethylcyclopentasiloxane, or D5 siloxane are under scrutiny as potentially harmful.
