Product Features & Advantages
Different from ordinary potting silicone with loose structure and weak dust resistance, this product has exclusive particle barrier strengths:
1. Powerful particle barrier: Dense cured layer fully blocks fine dust, debris and airborne contaminants, realizing long-term clean module protection.
2. Cleanroom compatible performance: Low volatile formula adapts to precision manufacturing environments, no secondary pollution to electronic components.
3. Multi-dimensional protection: Integrates dustproof, waterproof, anti-corrosion, shockproof and insulation functions with wide temperature adaptability.
4. Stable structural toughness: Absorbs thermal stress effectively, preventing cracking and particle penetration caused by temperature changes.
Application Scenarios
Ideal for cleanroom electronic equipment, precision sensors, semiconductor modules and high-end communication electronics. Its contamination blocking module potting performance avoids particle-induced short circuit and component failure, reduces product defective rates and cleaning maintenance costs, and improves long-term operational stability of precision electronic products.
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 particle barrier performance after curing.
3. Vacuum defoaming: Place mixed uniform glue in a 0.01MPa vacuum container for 3-minute defoaming to avoid barrier structure defects.
4. Curing treatment: Supports room temperature or heating curing; full curing takes 24 hours, affected by ambient temperature and humidity.
Certifications & Compliance
This product complies with ISO9001, CE and ROHS international standards, meeting cleanroom electronic packaging and global cross-border export specifications.

FAQ
Q1: What makes this particle barrier potting compound different from ordinary potting silicone?
A: It features a dense barrier structure and cleanroom compatibility, effectively blocking fine particles and contaminants that cause precision electronic failure.
Q2: Will colloid stratification affect dust barrier performance?
A: No. Slight storage stratification is normal, and even stirring will not damage its dense structure and particle blocking ability.
Q3: How to store mixed barrier potting silicone?
A: Seal raw materials and store in dry clean environments. Mixed glue should be used up at one time to avoid performance attenuation.
