Product Overview
This high-performance Electronic Encapsulation Adhesive covers addition curing and condensation curing grades, serving as high-purity industrial Silicone raw materials for RF hybrid junction packaging. It offers outstanding adhesion and thermal stability for PCB, PC, PMMA, CPU and multiple metal substrates including aluminum and copper. After curing, it forms a uniform, stress-relieved protective layer that absorbs thermal cycling stress, protects internal chips and gold bonding wires, and provides integrated insulation, waterproof, dustproof and anti-corrosion protection for hybrid junctions in complex high-frequency working environments.
Core Product Features & Advantages
Specially optimized for precision hybrid junction signal transmission requirements, it outperforms ordinary potting silicone in RF stability and structural reliability:
1. Stable hybrid signal performance: Constant dielectric parameters maintain accurate signal coupling, isolation and power distribution without RF interference or signal leakage.
2. Full environmental protection: Features excellent waterproof, moisture-proof, shockproof and anti-corrosion capacity, with strong resistance to ozone and chemical erosion.
3. Wide temperature endurance: Continuously stable from -60℃ to 220℃, offsets thermal expansion stress and avoids hybrid junction parameter shift under temperature cycling.
4. Low volatility & superior adhesion: Low volatile content and high structural strength, firmly bonds various substrates without affecting precision RF device performance.
Application Scenarios
Perfect for encapsulation and sealing of RF hybrid junctions, microwave hybrid couplers, multi-port signal hybrid modules and high-frequency precision communication components. Widely used in 5G communication equipment, RF test systems and aerospace electronic devices. It stabilizes hybrid junction signal accuracy, reduces device failure and debugging rates, improves finished product consistency, and lowers manufacturers’ production and after-sales 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 formulation.
2. Proportional mixing: Strictly follow standard AB component weight ratio to ensure stable RF performance.
3. Vacuum defoaming: Place mixed silicone in a 0.01MPa vacuum container for 3-minute defoaming to eliminate bubble-caused signal instability.
4. Curing treatment: Adopt room temperature or heating curing. Subsequent processes are available after initial curing, with full curing finished within 24 hours.

FAQ
Q1: Will this Potting Compound interfere with hybrid junction signal performance? A: No. It has ultra-stable dielectric properties, effectively maintaining precise signal coupling and isolation of hybrid junctions. Q2: Does colloidal stratification affect hybrid junction packaging quality? A: Slight stratification is normal after long storage. Even stirring will not damage its protective and RF stable performance.
Q3: How to store hybrid junction potting silicone? A: Keep sealed and dry. Mixed AB silicone should be used up at one time to prevent performance attenuation.
