Product Overview
Our Electronic Potting for Planar Transformers is a professional Silicone Encapsulant developed specifically for the encapsulation, sealing and protection of planar transformers. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for the thin design, high thermal conductivity and strong insulation requirements of planar transformers, focusing on heat dissipation, adhesion to planar windings/PCB and low shrinkage. Compared with ordinary potting compounds, it has better thermal conductivity, stronger adhesion to copper windings and PCB substrates, and can absorb internal stress caused by high-temperature operation and vibration, effectively protecting planar transformers and pins, reducing failure rates and extending service life for procurement partners.
Key Features & Advantages
- Superior Insulation & Anti-Interference: Excellent dielectric properties, ultra-strong insulation performance, effectively isolating planar transformer windings from external electrical and electromagnetic interference, preventing short circuits and coil breakdown, ensuring stable voltage conversion and reliable operation, meeting the strict insulation requirements of planar transformers.
- Excellent Heat Dissipation & Temperature Adaptability: High temperature resistance (-60℃ to 220℃) and outstanding thermal conductivity, can quickly dissipate heat generated by planar transformer operation (critical for thin designs), operate stably in extreme temperature environments, absorb internal stress caused by high-temperature cycles, and protect windings and PCB from damage.
- Strong Adhesion & Sealing: Excellent adhesion to planar transformer windings (copper), PCB substrates, aluminum, stainless steel, PC and PMMA, forming a tight seal, effectively achieving waterproof, moisture-proof, dust-proof and anti-corrosion effects, avoiding winding oxidation and short circuits caused by moisture or dust.
- Low Shrinkage & Easy Operation: Two-component liquid design, ultra-low curing shrinkage, no deformation to thin planar transformer structures; simple mixing ratio, easy to stir evenly, suitable for precise pouring; supports room temperature or heat curing, full curing in 24 hours, optional vacuum degassing, improving production efficiency for batch production of planar transformers.
- High Stability & Environmental Protection: Low volatility, high strength, no harmful substances, complying with EU RoHS and international environmental standards; no stratification or performance degradation after long-term storage, compatible with planar transformer materials, ensuring consistent product quality and stable performance.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A to mix the settled filler evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting the curing effect and adhesion to planar transformer windings and PCB substrates.
- Mixing: Mix Component A and Component B according to the specified weight ratio (customizable), stir slowly and evenly to avoid generating air bubbles, which will affect the insulation, heat dissipation and sealing performance, and prevent damage to delicate planar transformer structures.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.01MPa for 3 minutes to completely eliminate air bubbles, then it can be used for precise pouring into planar transformer molds.
- Curing: Pour the degassed potting compound into the planar transformer packaging mold, place it at room temperature for curing or heat to accelerate curing; after basic curing, proceed to the next process, and full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed.
