Product Overview
This high bond strength potting silicone includes addition curing and condensation curing formulas, dedicated to encapsulation, sealing, filling and pressure protection of various electronic components. It achieves ultra-strong adhesion and superior thermal stability on PCB, PC, PMMA, CPU, aluminum, copper and stainless steel surfaces. Cured silicone effectively absorbs thermal cycling stress to protect chips and gold bonding wires. It integrates waterproof, insulation, dustproof, shockproof, ozone and chemical corrosion resistance, ensuring long-term tight bonding and stable protection for electronic devices.
Technical Specifications
This high-adhesion Silicone Encapsulant features industry-leading bond strength with ultra-low volatile content and high structural toughness. It supports continuous stable operation in -60℃ to 220℃, maintaining permanent tight adhesion without peeling or falling off under temperature cycling and vibration. It boasts excellent anti-aging and chemical erosion resistance. Viscosity, hardness and operating time can be fully customized to fit diverse electronic packaging demands.
Product Features & Advantages
Different from ordinary potting silicone with weak adhesion, this product owns prominent bonding advantages:
1. Ultra-high bond strength: Firmly adheres to various metal and non-metal substrates, effectively avoiding glue layer peeling and sealing failure.
2. All-round protective performance: Combines waterproof, moisture-proof, dustproof and shockproof functions with great ozone and chemical resistance.
3. Extreme temperature adaptability: Stabilizes performance in wide temperature ranges and buffers internal thermal stress effectively.
4. High purity & stability: Low volatile formula causes no pollution to precision circuits, ensuring long-term device stability.
Application Scenarios
Widely applied in automotive electronics, power modules, household electrical components and industrial control equipment that require high tightness. Its strong bonding performance prevents glue layer delamination caused by vibration and temperature changes, reduces equipment failure rates and maintenance costs, improves finished product durability and qualification rate, and brings higher economic benefits to manufacturers.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A evenly to mix settled fillers completely and shake component B thoroughly.
2. Proportional mixing: Strictly follow standard AB component weight ratio to guarantee stable high bonding performance.
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, affected by ambient temperature and humidity.
Certifications & Compliance
