- Comprehensive Protection: Waterproof, moisture-proof, dust-proof and anti-corrosion, resisting ozone and chemical erosion, protecting precision piezoelectric components from harsh industrial environments.
- Friendly Curing Process: Addition-curing formula, no heat release, low shrinkage and no corrosion; supports room-temperature or heated curing, 24-hour full solidification, easy to operate and adapt to mass production.
- High Reliability & Customizability: As a professional Silicone Potting Compound manufacturer, it has high strength and excellent adhesion to actuator substrates; hardness, viscosity and operation time can be customized to match different piezoelectric actuator models.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously to ensure uniformity, avoiding stratification which affects adhesion and stress relief performance.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly for 2-3 minutes to avoid introducing air bubbles that affect component protection.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of piezoelectric actuator components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature (full solidification in 24 hours) or heated to accelerate. Note: Environment temperature and humidity have a significant impact on curing speed.
