Bare metal substrates are easily corroded under natural conditions, and coating a layer of paint on the surface of the metal substrate is the most common and easiest way to alleviate the corrosion of the metal substrate. However, due to the difference in chemical properties between the metal substrate and the coating, the bonding force between the metal substrate and the coating is very limited, a

1. Uv curing principle The first patent for ultraviolet (UV) curable coatings was born in 1947. After half a century of development, UV curable coatings have become a relatively mature technology, especially with the improvement of people's environmental awareness, production and researchers pay more attention to the development and application of UV curable coatings. UV curable coating is a kind

There is also a method to identify "silicone oil" in shampoo on the Internet: add shampoo to clean water and stir, if the water becomes cloudy after standing, then the shampoo is added with silicone oil; if it remains clear, then there is no silicone oil . It is said that the principle of this identification is because silicone oil is insoluble in water and will appear turbid in water. Silicone oi

Silicone oil is a liquid polyorganosiloxane with excellent high and low temperature resistance, chemical stability, shear resistance, viscosity-temperature characteristics and high compressibility. Vibration-absorbing products based on silicone oil are widely used in electronic and electrical equipment, high-rise buildings, bridges and weapon platforms. A large number of related patents have been

There are also types of silicone products, such as liquid silicone products, silicone products, flat-pressed silicone products, etc. Recently, friends often ask about the difference between liquid silicone products and flat-pressed silicone products. Today, the editor will tell you the difference between liquid silicone products and flat-pressed silicone products. There is an essential differen

The structure of thermosetting liquid silicone rubber (LSR) injection molds is generally similar to that used for thermoplastic rubber, but there are also many significant differences. For example, LSR compounds generally have a low viscosity, so the filling time is very short, even at very low injection pressure. To avoid air entrapment, it is critical to have good venting in the mold. In addi

n-Propyltrimethoxysilane is an important silicone rubber crosslinking agent, which can effectively improve the performance of silicone rubber and expand the application scenarios of silicone rubber. In addition, n-propyltrimethoxysilane has excellent performance in hydrophobic modification, and it also has application potential in the preparation of airgel. In the field of silicone rubber cross

Silicone surfactant is a large amount of surfactant in the daily chemical industry. It can be used in various cosmetics. It is used as an emulsifier in essence and shampoo. It has the functions of emulsification, foaming, dispersion and solubilization. It can make the shampoo foam rich, fine and stable, and has antistatic effect. Silicone surfactants have no side effects on the human body, can for

Airgel is a new lightweight porous solid material. Due to its low density, high specific surface area and excellent thermal insulation performance, it has been widely used in many fields such as petrochemical industry, thermal pipeline, ship hull insulation and building insulation. IOTA Si40 (Ethyl silicate 40), is one of the main raw materials for preparing airgel. Compared with other airgel p
