Coated silicone is a functional coating material based on organic silicon polymers, which has demonstrated significant advantages in multiple industrial fields due to its unique chemical structure and physical properties. Its main chain is composed of polysiloxane. The Si-O bond can endow it with excellent high temperature resistance and weather resistance, which can be stable in a wide temperature range from -60 ℃ to 250 ℃. At the same time, it is resistant to strong acids and bases (except hydrofluoric acid), ultraviolet radiation, hydrophobic and anti-aging. Its biocompatibility meets FDA food grade standards. Some products have high temperature resistance over 300 ℃.

This material is non-toxic and odorless, with low volatile organic compound content, and meets environmental requirements such as RoHS, making it an ideal choice for fields such as electronics, automotive, medical, and construction.

At the application level, the functionality of coating silicone is reflected in multiple scenarios: in the field of electronics and electrical engineering, it is used for circuit board protection to prevent short circuits and oxidation, assist in LED heat dissipation, provide wire harness insulation and semiconductor device surface protection; In industrial manufacturing, its presence can be seen in the production of high-temperature resistant seals for automotive components, protection for aerospace equipment, anti-corrosion insulation fabrics (such as waterproof and high-temperature resistant fabrics), and outdoor tent fabrics.

In the medical and consumer fields, the biocompatibility requirements of medical devices, food grade packaging, fabric coatings (anti slip and wear-resistant), and the production of medical socks depend on their characteristics; In both architecture and daily scenarios, the production of building seals, umbrella cloths, anti-aging fabrics, and anti slip tablecloths also relies on its support.

In terms of process flow, the preparation of coated silicone requires strict pretreatment, coating operation, and post-treatment after curing. In the preprocessing stage, the substrate needs to undergo three-level cleaning - chemical cleaning to remove oil and oxides, physical wiping to remove particles, and plasma treatment to enhance adhesion; Silicone gel itself needs to be stirred to eliminate paste agglomeration, while the sheet needs to be adapted to a constant temperature and humidity environment of 15-25 ℃ for 24 hours.
