As we all know, silicone materials have a wide range of uses in various industries and fields, and have excellent performance due to their unique chemical structure. It is this that has resulted in silicones occupying a rather important position in the national economy. This application is especially manifested in the coatings industry.
1. Silicone resin coatings.
Silicone resin as a film-forming material made of coatings are mainly heat-resistant weathering silicone anti-corrosion coatings, scratch-resistant transparent silicone coatings, mold release and moisture-proof coatings and radiation-resistant coatings and other varieties.
2. Modified silicone resin coatings.
Modification methods have physical blending and chemical modification of two kinds, the effect of chemical modification is generally better than physical blending modification. Chemical modification is mainly at the end of the polysiloxane chain or side chain lead active groups, and then react with other polymers to generate block, join or interpenetrating network copolymer, so as to obtain new properties. In the coatings industry, the main organic resins modified with silicone are alkyd resins. Acrylic resin, epoxy resin and so on.
3. Silicone modified alkyd resin coatings
Silicone-modified alkyd resin coating retains the advantages of alkyd resin paint room temperature curing and film physical and mechanical properties, but also has a silicone resin heat resistance, ultraviolet aging and good water resistance, is a comprehensive performance of the coating.
4. Silicone-modified other resin coatings
Silicone-modified polyurethane coatings are widely used in aircraft skins, large tank surfaces, building roofs and protection of cultural relics. Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, with hydroxyl-terminated polydimethylsiloxane and alcoholysis castor oil modified polyurethane prepolymer for blending modification, blends of curing speed has been improved, film adhesion, hardness, heat resistance has also been improved. The Institute also uses silicone-modified lacquer phenol resin as the base material to produce coatings with resistance to boiling water and water vapor permeability, which can be used for long-term corrosion protection of equipment.
