The organopolysiloxane resin is a semi-inorganic, semi-organic polymer compound which combines the characteristics of an organic polymer and an inorganic polymer. These properties include high and low-temperature resistance, weathering resistance, electrical insulation, ozone resistance, water repellency, flame retardancy, physiological inertness, oil resistance, solvent resistance, and radiation resistance.
The large-scale commercialization of polysiloxanes for industrial coatings appeared in the 1990s and is currently not often used alone.
By using polysiloxanes with many organic monomers and polymers, formulators can develop specific blends that have both organic and inorganic material functionality. The "organic-inorganic hybrid" coating uses an organic blend-modified resin containing an organopolysiloxane resin.
With the deepening of research on hybrid coatings, the application of organopolysiloxane resins will have a great development, and the final outbreak may be the result of technology, environmental pressure, and cost performance.
Polysiloxane retains its physical properties over an exceptionally wide temperature range (-100 ° C to 250 ° C). Its T is as low as -127 ° C, so it has outstanding low-temperature flexibility. Secondly, it is resistant to high temperature and oxidation， has good stability in chemical and physiological environments, and has good weather resistance, water repellency, and dielectric properties. Polysiloxanes have a wide range of uses, and their liquid products are used as defoamers, fiber rinses, surfactants, lubricants, vacuum greases, and heated oil baths. Resins are used as varnishes, paints, mold release agents, adhesives and insulating materials. Elastomers are used as sealing materials, electrical insulating materials, gaskets, and tubes, etc., and can also be used as medical materials such as artificial heart valves, pacemakers, contact lenses, and plasma bottle inner coatings. These are part of polysiloxane uses. Compared to other organic elastomer materials, the strength of silicone elastomers is relatively poor, so the addition of filler reinforcement is more important.
