Its low-chloride and corrosion-free performance eliminates latent circuit failure risks, extends electronic service life, reduces product defective rates and after-sales costs, and upgrades product reliability for high-end manufacturing.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A evenly to disperse settled fillers completely and shake component B thoroughly.
2. Proportional mixing: Strictly follow standard AB component weight ratio to maintain stable low-chloride performance after curing.
3. Vacuum defoaming: Place mixed uniform glue in a 0.01MPa vacuum container for 3-minute defoaming before pouring.
4. Curing treatment: Supports room temperature or heating curing; full curing takes 24 hours, greatly affected by ambient temperature and humidity.

FAQ
Q1: Why is low chloride potting silicone essential for high-end electronics? A: Ultra-low chloride ions avoid metal circuit corrosion and oxidation, solving latent failure risks caused by high-ion ordinary potting adhesives.
Q2: Will colloid stratification affect product purity? A: No. Slight storage stratification is normal, and even stirring will not change its low-chloride purity and protective performance.
Q3: How to store mixed low chloride Potting Compound? A: Seal raw materials and store in dry environments. Mixed AB silicone should be used up at one time to prevent performance attenuation.
