Product Overview
This high-performanceElectronic Encapsulation Adhesive includes addition curing and condensation curing formulas, serving as premium industrial Silicone raw materials for precision attenuator packaging. It delivers excellent adhesion, sealing and thermal stability for PCB, CPU, PC, PMMA and multiple metal substrates. After curing, it forms a uniform protective layer that absorbs high-temperature cycling stress, shields internal chips and gold bonding wires, and provides all-round insulation, waterproof and anti-corrosion protection for precision attenuator devices.
Core Product Features & Advantages
Specially optimized for precision attenuator working requirements, it outperforms ordinary potting silicone in parameter stability:
1. Ultra-stable attenuation performance: Constant dielectric properties ensure precise and consistent signal attenuation, no parameter drift in long-term operation.
2. Full comprehensive protection: Integrates waterproof, moisture-proof, dust-proof, shockproof and anti-corrosion functions, with strong resistance to ozone and chemical erosion.
3. Extreme temperature adaptability: Stably operates at -60℃ to 220℃, maintaining accurate attenuation values during frequent temperature changes.
4. Low volatility & high bonding strength: Minimal volatile content and high structural stability, firmly bonding various substrates without interfering with precision signal control.
Application Scenarios
Ideal for encapsulation and sealing of RF precision attenuators, signal adjustment modules, high-precision communication attenuation devices and test instrument components. Widely used in communication equipment, precision testing instruments and aerospace electronic systems. It stabilizes signal attenuation accuracy, reduces product calibration failure rates, improves finished product qualification rate, and cuts manufacturers’ production and maintenance costs.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A to evenly disperse settled fillers and shake component B thoroughly for uniform performance.
2. Proportional mixing: Strictly follow standard AB component weight ratio to ensure stable precision protection performance.
3. Vacuum defoaming: Place mixed silicone in a 0.01MPa vacuum container for 3-minute defoaming to eliminate bubbles affecting precision parameters.
4. Curing treatment: Adopt room temperature or heating curing. Initial curing allows subsequent processing, with full curing completed within 24 hours.

FAQ
Q1: Will this potting glue affect the attenuation accuracy of precision attenuators? A: No. It features ultra-stable dielectric performance with zero parameter drift, fully protecting the precision of attenuator devices.
Q2: Does colloidal stratification influence product precision performance? A: Slight stratification is normal after long storage. Even stirring will not damage its protective and precision stabilization performance.
Q3: How to store the precision attenuator Potting Compound? A: Keep sealed and dry. Mixed AB silicone should be used up at one time to avoid performance attenuation.
