Potting glue is mainly used in the bonding and sealing of electrical components, and can even be used in the overall potting and coating of electrical substrates, the field of use is very wide, as long as the reasonable performance of the use, can show good waterproof, moisture-proof, sealing and other performance, has become one of the indispensable materials for the electrical and electronic manufacturing industry.
Potting adhesive can be selected according to the use of substrates?
1, potting adhesive can be selected according to the use of substrates to select the appropriate type, specifications. Before use, understand the compatibility of potting adhesive and substrate, only when the two "match" can be considered for use.
2, potting adhesive before use, need to understand the adhesive and the substrate needs between the adhesive, to understand these properties to facilitate the selection. Such silicone potting adhesive adhesion performance is poor, easy to repair after use. Epoxy potting adhesive after curing bonding performance is strong, can not be disassembled for repair, replacement of electrical groups is a disposable product.
3, potting adhesive before use, you need to understand the substrate requirements for the hardness of the glue. Silicone potting adhesive is soft after curing, has good elasticity, can protect the substrate. Epoxy potting adhesive cured hardness is higher but moisture-proof, waterproof performance is better, there is good pressure resistance, insulation.
4, potting glue before use, need to understand the substrate environment, the use of different environments to effectively select the glue, some potting glue after curing waterproof moisture resistance performance is better, there is potting glue after curing corrosion resistance, anti-aging performance is better. Different performance is destined to use different substrate areas.
There are more types of potting adhesives, if divided according to raw materials, can be divided into silicone potting adhesive, epoxy potting adhesive, polyurethane potting adhesive, and so on. If divided according to the components can be divided into one-component and two-component, the user carefully identifies when buying, find the right product to play the performance.
