LED silicone is the general term for organic silicone materials in the LED optoelectronics industry. Since epoxy has a weak ozone resistance, the colloid turns yellow, affecting the light transmission effect, while silicone has excellent properties such as resistance to atmospheric aging and ultraviolet aging. In high-end product applications, epoxy resin has been replaced by LED silicone materials.

Thermal grease is a common thermal conductive material that is currently used in many electrical appliances. Although thermal grease is classified as a chemical substance, it does not corrode metals, plastics, ceramics, and other substrates. It does not release volatile substances on the electrical substrate during use, ensuring human health.

Silicone grease, the full name of which is thermal conductive silicone grease, commonly known as thermal paste or heat dissipation paste, is a paste made of special silicone oil as the base oil, mixed with new metal oxides and other functional additives, and processed by a specific process. ‌Performance and Use‌: Silicone grease has good thermal conductivity, waterproof sealing, solvent resistance and anti-creeping performance, does not corrode metal, and has good adaptability with rubber. It is widely used in bathroom equipment, sealing rings, waterproof sealing and lubrication in the electronic and electrical industries, especially as a thermal conductive medium filled between chips and radiators. ‌Ingredients and Appearance‌: Silicone grease is usually white or other colors, and the specific color varies depending on the material. It uses silicone oil as the base oil, mixed with metal oxide powders such as aluminum oxide and zinc oxide, and the overall appearance is mostly gray and non-conductive. This article will conduct an in-depth discussion on the basic principles of silicone grease, factors affecting consistency, methods for regulating consistency, and application examples.

Silicone oil is an organic silicon compound primarily synthesized through chemical reactions. It is commonly used as a lubricant, waterproofing agent, and coating additive in industrial production.

Polyether modified silicone oil, a kind of silicone nonionic surfactant, is synthesized by graft copolymerization of polyether and dimethylsiloxane. Its performance can be customized by adjusting the number of silicone oil segments, hydrogen content, the ratio of polyether EO to PO, its segment length and terminal groups to meet the needs of different industries. Polyether modified silicone is often used as an emulsifier, defoamer, wetting agent and leveling agent in coatings.

Organic silicon resin coating is a type of elemental organic coating, abbreviated as organic silicon coating, mainly composed of organic silicon resin or modified organic silicon resin as the film-forming substance. Elemental organic coatings are a general term for coatings mainly composed of elemental organic polymers as film-forming substances, including organic silicon, organic titanium, organic fluorine, organic aluminum, organic zirconium coatings, etc. Among them, the production of silicone resin coatings is the largest. Elemental organic coatings are a type of compound between organic polymers and inorganic compounds, with special thermal stability, insulation properties, high temperature resistance, chemical resistance, water resistance, weather resistance, and other characteristics. They are widely used in industries such as national defense and electrical appliances.

Do you know about organic silicon? It is a polydimethylsiloxane (organosilicon resin) composed of silicon oxygen bonds (- Si-O-Si -) as the skeleton, belonging to semi organic and semi inorganic polymer compounds with significant industrial value. Silicon containing polymers can be divided into four major forms: silicone oil, silicone rubber, silicone resin, and silane coupling agent. Silicone oil, mainly used as a coating additive, is one of the most effective defoaming agents in coatings. It also has the function of improving the leveling of coatings and preventing the phenomenon of foaming.

Application of silicone oil in coatings and paints: Application of silicone oil in polishing, surface treatment agents, coatings, and plastics

In common silicone oils, we often encounter emulsified silicone oil and water-soluble silicone oil. So, what exactly is the difference between these two types of silicone oil? Let's first explore what these two types of silicone oil are.
