Its professional magnetic field shielding performance eliminates magnetic interference failure, improves electronic signal accuracy and operational stability, reduces product defective rates and after-sales maintenance costs, and enhances product market competitiveness.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A evenly to disperse settled fillers completely and thoroughly shake component B before mixing.
2. Proportional mixing: Strictly follow standard AB component weight ratio to ensure stable magnetic shielding performance after curing.
3. Vacuum defoaming: Place mixed uniform glue in a 0.01MPa vacuum container for 3-minute defoaming to ensure dense shielding structure.
4. Curing treatment: Supports room temperature or heating curing; full curing takes 24 hours, and curing efficiency is affected by ambient temperature and humidity.

FAQ
Q1: What is the core value of magnetic field shielding potting compound?
A: It provides professional EMI suppression encapsulation and flux containment, protecting sensitive electronics from magnetic field interference and signal failure.
Q2: Will colloid stratification affect shielding performance?
A: No. Slight storage stratification is normal, and even stirring will not weaken its magnetic isolation and interference rejection capabilities.
Q3: How to store mixed shielding potting silicone?
A: Seal raw materials and store in dry environments. Mixed AB silicone should be used up at one time to avoid performance attenuation.
