what is platinum
The English of platinum is Platinum, and the chemical symbol is Pt. Platinum is a metal more expensive than gold due to its excellent natural properties and rare reserves in nature, so it is not easy to mine. As of October 27, the closing price of platinum was 199.26 yuan/g.
Characteristics of Platinum
1. Excellent physical properties, with silvery white luster and high melting point, reaching 1773°C.
2. The density is very high, 21.4 g/cm.
3. The chemical properties are stable, and it is not easy to react chemically with other substances.
4. High resistivity.
Application of Platinum in Silicone Industry
Because platinum has the characteristics of high resistance, high melting point and good ductility, it is often used as electrodes and electrical contacts in special electrofusion. In the silicone industry, some catalysts will also add platinum, which is what we often call platinum catalysts, which are widely used in electronic potting compounds in the electronics industry.
However, electronic potting adhesives are easy to be poisoned (not cured) during use. Silicone potting adhesives are relatively environmentally friendly potting adhesives. Platinum curing agents are relatively active and easily react with other impurities, causing poisoning. This requires strengthening the quality control of the adhesive, improving the anti-toxicity of the colloid, maintaining a stable curing ability, and at the same time requiring a certain bonding ability.
Anti-poisoning platinum catalyst
It is a platinum catalyst with high activity and high transparency. It is a completely anti-poisoning and high-efficiency platinum catalyst developed mainly for LED power potting adhesives. It can effectively inhibit the accompanying side reactions during the Si-Vi and Si-H reactions.
It has good stability and strong anti-toxicity, avoids the formation of black substances, and overcomes the phenomenon of yellowing and blackening that occurs when using other similar products.
