Is the selection method of potting glue based on the base material reliable?


Potting glue is mainly used for bonding and sealing of electrical components, and can even be used for the overall potting and coating of electrical substrates. It has a wide range of uses. As long as it is used properly, it can show good waterproof and moisture-proof properties, sealing and other properties, it has now become one of the indispensable materials in the electrical and electronic manufacturing industries.

Can the potting glue be selected according to the substrate used?

1. The suitable type and specification of potting glue can be selected according to the base material used. Before use, understand the compatibility of the potting glue and the substrate. Only the two "match" can be considered for use.

2. Before using the potting glue, you need to understand the required adhesion between the glue and the substrate. Only by understanding these properties can you choose easily. If the silicone potting adhesive has poor bonding performance, it is easy to repair after use. The epoxy potting glue has strong bonding performance after curing and cannot be disassembled for repair or replacement of electrical components. It is a disposable product.

3. Before using potting glue, you need to understand the hardness requirements of the base material for the glue solution. Silicone potting glue becomes soft glue after curing, has good elasticity and can protect the substrate. Epoxy potting glue has a high hardness after curing, but has good moisture-proof and waterproof properties, as well as good pressure resistance and insulation properties.

4. Before using the potting glue, you need to understand the usage environment of the substrate. Choose the glue solution effectively according to the usage environment. Some potting glues have better waterproof and moisture-proof properties after curing, while others are corrosion-resistant and anti-aging after curing. Better performance. Different properties are destined to be different in the field of substrate materials.

5. Before using the potting glue, you need to understand the usage temperature of the substrate. If you do not master this and blindly select the potting glue, thermal expansion and contraction will easily occur after curing. The poor temperature resistance is not conducive to large-scale promotion and use. Different brands have different temperature resistance indexes. Brands of potting glue have many specifications and guaranteed temperature resistance. For example, TENSAN focuses on the research of potting glue and provides customized potting glue application solutions. It has a wide range of uses and can be used in New energy, military industry, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

There are many types of potting glue. If divided according to raw materials, they can be divided into silicone potting glue, epoxy potting glue, polyurethane potting glue, etc. If divided according to components, it can be divided into single-component and two-component. Users must carefully identify them when purchasing to find the right product to achieve the best performance.
