Polyurethane potting glue is also called electronic potting glue. Its hardness is moderate, ranging from 50 to 70, it can resist pressure very well and will not break inexplicably. It is polymerized from polyester, polyether and other substances and has many properties. Multiple industries can benefit from choosing high-quality adhesives that deliver performance. So, what are the main features of polyurethane potting glue? What are the advantages and disadvantages?
1. What are the main characteristics of polyurethane potting glue?
During use, this adhesive showed very good performance. It has good elasticity and can be effectively waterproof, moisture-proof and mold-proof, preventing and isolating substances that may harm the protected object. It has good electrical insulation and uses flame-retardant raw materials, which greatly improves the flame-retardant performance and safety. ; It is not corrosive by itself and will not corrode components. However, when we choose polyurethane potting glue and cooperate with powerful suppliers, we are more assured and have a wide range of uses. It can be used in new energy, military industry, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
2. What are the advantages of polyurethane potting glue?
<span style During use, polyurethane will be found The waterproof and acid-resistant properties of the potting glue are very good. Many devices that are exposed to water for a long time require this kind of adhesive to seal them. In addition to being waterproof, it is also flexible and impact-resistant. Under the impact of external force, it will deform a little, but it will quickly return to its original shape. It will neither affect its own use nor cause harm to the protected objects.
3. What are the disadvantages of polyurethane potting glue?
If polyurethane potting glue has no disadvantages , is unrealistic. The main disadvantage is that there are too many bubbles, which are small and dense. If there are a few bubbles, they can be automatically eliminated. Once there are too many bubbles, vacuum processing can only be performed. Although the operation process is complicated, it cannot be ignored.
For industries with higher requirements, you want to use polyurethane You have to think twice before potting glue. Even if it is used, the operating process must be strictly followed to eliminate air bubbles.
