Because of the diversity of preparation methods and the particularity of structure, silicone modified polyester resin has great application value, especially in coating industry. It can be used in the production of high temperature resistant coatings, powder coatings, H class insulating paint, electrical components for sealing, impregnated glass cloth, glass tubes, enameled wire, metal sheet coil coatings, etc. The main research results in recent years are: Shanghai zhenhua paint factory development of silicone modified polyester coil coating except having excellent properties of polyester coil coatings, in outdoor weatherability, optical, color retention, etc also have greatly improved, artificial aging test increased from 1000 h to 2000 h, T also further improve the bending performance, has been used in the light of China's largest color plate factory The unit. Coatings industry research and design institute made by polyester/silicone resin as the base material, aliphatic isocyanate as curing agent can be cured at room temperature, mainly used for large civil aircraft and automobile coating. In the 21st century, with the strengthening of people's awareness of environmental protection, various countries have introduced laws and regulations to limit the use of volatile organic compounds (VOC). In addition, the world oil crisis, the powder coating because of no solvent, no pollution, save energy and resources, reduce labor intensity and high mechanical strength of coating advantages and entered the stage of rapid development. Powder coating is a kind of 100% solid coating, mainly used for automobile, exterior wall, road guardrail and so on. Due to long-term exposure to the outdoors, the weatherability of the coating is required to be higher. The powder coatings made of silicone modified polyester just meet the requirement, so they are widely used.
