Silicone coatings are also very useful for their inherently low or non-flammability
Silicone resins are formed by branched oligosiloxanes. These groups can be further condensed in many applications to give highly crosslinked, insoluble Polysiloxane systems. Such systems have physical scratch resistance and chemical resistance. Elastomeric silicone coatings, with fewer cross links, do not provide good resistance to strong acids or bases. Strong acids or bases, in particular at elevated temperatures, can cause depolymerization of the siloxane backbone, resulting in failure or dissolution of the coating.
Suitably formulated Silicone resins can resist temperatures up to +650°C (1202°F).
Silicone resins have very high chemical bond energies, so the chemical processes usually associated with aging of coated surfaces are often much slower. Indeed, in many situations aging is virtually eliminated. And because the Silicone-Carbon and Silicone-Oxygen bonds are not present in the natural organic world, biocompatibility and resistance to degradation via biochemical and biophysical processes are significantly reduced.
When combined with their hydrophobicity (with simultaneous vapour permeability) , oxygen resistance, outstanding oxidation resistance and ozone resistance properties, silicones provide excellent weatherability.
Silicone coatings are also very useful for their inherently low or nonflammability.
Silicone is a versatile, recyclable, malleable, non-toxic and flexible compound that is water-resistant and heat-resistant. Silicone resin based coatings have outstanding mechanical properties and are durable, sustainable and economic.
