It features good fluidity, deep curing ability, wide temperature adaptability (-50℃ to 250℃), 1:1 weight ratio, non-toxic and pollution-free, complying with EU RoHS, and supporting full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting for Piezoelectric Discs is a professional Silicone Encapsulant developed for the encapsulation, protection and performance preservation of piezoelectric discs. As a leading manufacturer of Electronic Potting Compound and silicone raw materials, we optimize the formula for the high transparency, elasticity and UV resistance requirements of piezoelectric discs. Unlike ordinary potting silicones, it maintains high light transmittance after curing, does not affect piezoelectric disc signal transmission, has excellent flexibility to adapt to piezoelectric vibration, and ensures long-term stable operation, helping procurement partners improve product quality and service life.
Key Features & Advantages
- Super High Transparency & Light Transmission: Cured transmittance reaches 95% at 450nm (2mm thickness), refractive index 1.41, ensuring no obstruction to light transmission and signal propagation of piezoelectric discs, maintaining their original performance and precision.
- Excellent UV Resistance & Durability: Outstanding UV aging resistance, not yellowing or aging under long-term UV irradiation, maintaining transparency and performance stability, suitable for outdoor and light-exposed piezoelectric disc applications.
- Wide Temperature Adaptability & High Elasticity: Operates stably from -50℃ to 250℃, with excellent high and low temperature resistance; cures into soft rubber (Shore A 20±3), high elasticity to adapt to piezoelectric disc vibration, avoiding damage caused by mechanical stress.
- Good Fluidity & Easy Operation: Two-component (1:1 weight ratio) liquid design, low viscosity (500±100 mPa.s), good fluidity, capable of filling tiny gaps of piezoelectric discs, realizing fast deep curing; easy to mix evenly, optional vacuum defoaming, improving production efficiency.
- Environmental Protection & High Stability: Addition-curing silicone, solvent-free, non-toxic and pollution-free, fully compliant with EU RoHS; low volatility, no stratification after long-term storage; strong adhesion to piezoelectric disc materials, ensuring stable encapsulation and no detachment.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Mix Component A and Component B separately in a dry container to ensure uniform consistency; ensure the container is clean and free of impurities, avoiding contact with oxygen, phosphorus, sulfur and metal compounds that may affect curing.
- Mixing & Defoaming: Mix Component A and Component B at a 1:1 weight ratio, stir slowly and evenly, then let it stand for defoaming or vacuum degas to remove air bubbles, ensuring no bubbles remain in the mixed glue.
- Encapsulation: Clean the piezoelectric disc to be encapsulated, dry it thoroughly (keep the disc surface dry), then pour the mixed glue into the packaging mold, ensuring the disc is fully wetted and covered.
- Curing: Place the encapsulated piezoelectric disc into an oven for curing; adjust the curing speed by changing the temperature, ensuring full curing to maintain transparency and elasticity, and avoid affecting the disc's performance.
