FAQ
Q1: Why choose low outgassing potting compound for precision electronics? A: It minimizes volatile precipitation, effectively preventing optical pollution, signal interference and component performance degradation of high-precision devices.
Q2: Is stratified silicone usable after long storage? A: Yes. Slight stratification is normal, and uniform stirring will not affect its low outgassing and protective performance.
Q3: How to store and use mixed low outgassing potting glue? A: Store raw materials in sealed and dry environments. Mixed AB silicone should be used up at one time to avoid performance changes.
