Adhesion is another important indicator for measuring the mechanical properties of silicone resins. Silicone resin has good adhesion to metals such as iron, aluminum, silver, and tin, and is also easy to bond to glass and ceramics. Generally speaking, pre-treatment of these materials is not necessary, but if mechanical cleaning methods such as sandblasting are used on the surface of the substrate, it can improve the adhesion of silicone resin to metals, especially iron. The adhesion of silicone ...

The main chain of organic silicon is very flexible, and this excellent flexibility is due to the basic geometric molecular structure. Due to the much weaker intermolecular forces between its molecules compared to similar compounds, it has lower viscosity, weaker surface tension, lower surface energy, stronger film-forming ability, and excellent anti adhesion and demolding properties. It can be used as a high-temperature resistant and durable demolding agent. This low surface tension and low surf ...

The weather resistance of modified silicone resin increases with the increase of siloxane content, and is related to the types of siloxanes and organic resins used, as well as the modification methods. For example, modified resin coatings prepared by introducing 30% organic silicone resin into alkyd resin can dry at room temperature and have outdoor exposure performance 2-3 times higher than alkyd coatings. For example, S! - Comparison of aging tests (using ATLASUVCON irradiation) on acrylic mod ...

The heat resistance of alkyd modified silicone resin is related to the type of alkyd resin used. The effect of different alkyd resins on the heat resistance of modified silicone resin. After mixing heat-resistant fillers (pigments) into modified silicone resin, its usage temperature can be further increased. For example, the use temperature of alkyd modified silicone resin mixed with aluminum powder can be increased from 150 ℃ to 450 ℃.The heat resistance of modified silicone resin is between ...

Happy Father Day! Father is a mountain, tough ridge, upright fragrance of the earth.Thank you to all the fathers.

The thermal decomposition products of silicone resin depend on its original composition.The thermal aging life of silicone resin insulation paint is often evaluated using the bending assessment method, which involves coating a thin copper sheet with a thickness of 0 08 0 After aging at a predetermined temperature for a certain period of time, a 10mm insulation paint is bent and tested on a round rod with a diameter of 3mm until the paint layer cracks.The performance of silicon paint used for coi ...

The Dragon Boat Festival, also known as the Dragon Boat Festival, the Double Ninth Festival, the Dragon Boat Festival, the Mid Autumn Festival, and so on, together with the Spring Festival, the Tomb sweeping Day, and the Mid-Autumn Festival, is known as China's four major traditional festivals.Dragon Boat Festival has many traditional customs, such as dragon boat racing, hanging wormwood, eating Zongzi, and taking colorful ropes.According to the Notice of the General Office of the State Council ...

When subjected to thermal oxidation, a stable protective layer rich in Si-0-Si chains is formed on the surface of organic silicon polymers, reducing the impact on the internal structure of the polymers. Therefore, silicone resin has a high thermal decomposition temperature, can be used for a long time at 200-250 ℃ without decomposition or discoloration, and the Si-0 Si chain only begins to break at 350 ℃; Stable at room temperature, after crosslinking and curing, it can withstand high temperat ...

The most commonly used method for preparing thermosetting methylphenyl silicone resin is through co hydrolysis condensation reaction of two functional and three functional organic silicon monomers.There are two ways in the condensation reaction process: intermolecular condensation and intramolecular condensation. Only intermolecular condensation can increase molar mass. In the manufacturing process of silicone resin, the key to controlling the molar ratio is the ratio of intermolecular and intra ...
