FAQ
Q1: What safety benefits does this flame retardant potting silicone provide? A: It blocks flame spread and circuit combustion risks, greatly improving the safety and reliability of electronic devices.
Q2: Can stratified silicone be used normally after storage? A: Yes. Slight stratification is normal, and even stirring will not affect flame retardant and protective performance.
Q3: How to store and use mixed potting glue? A: Keep raw materials sealed and dry. Mixed AB silicone should be used up at one time to avoid performance degradation and waste.
