In electronic and electrical industries, silicone sealant will be used to seal and protect electronic equipment and other products. After normal curing, the dust, moisture, moisture and other isolated outside, resist the change of high and low temperature, protect the components work safely. Once it fails to cure properly, it must be resolved immediately.
Why does silicone potting glue not cure?
1, the electronic scale is not accurate enough, resulting in the incorrect content of AB agent. When there is too much agent A and too little agent B, it cannot be cured normally.
2. Curing time is not long enough, so we are in a hurry to carry out the next step. Or curing temperature is too low, so that the adhesive can not finish curing. Especially in winter, the temperature is low and the curing time needs to be extended.
3, adhesives expired, after the shelf life is likely to change, can not be used normally. Look at the expiration date before use and do not use expired products. Xishun silicone focus on silicone posealant research, provide customized silicone posealant application solutions, a wide range of uses, can be applied to new energy, military, medical, aviation, shipping, electronics, automotive, instruments, power supply, high-speed rail and other industries.
4, in the process of use, it is possible to have contact with nitrogen, phosphorus or sulfur compounds, and may also be exposed to unsaturated polyester or polyurethane products, resulting in "poisoning" phenomenon.
