HONG YE SILICONE Electronic Potting for Thermoelectric Coolers is a specialized Electronic Potting Compound and Silicone Encapsulant, also known as Electronic Encapsulation Adhesive, tailored for thermoelectric cooler (TEC) encapsulation. Made of high-purity Silicone raw materials, it is a two-component RTV silicone with low viscosity, 1:1 weight ratio, fast room-temperature deep curing, excellent waterproof and insulation performance, thermal conductivity (≥0.2 W/(m·K)), flame retardancy (UL94-V1), complying with EU RoHS, non-hazardous, and supporting full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting for Thermoelectric Coolers is a professional Silicone Potting Compound developed for the encapsulation, waterproofing, insulation and protection of thermoelectric coolers. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for the high insulation, waterproof sealing and temperature difference adaptability requirements of TECs. Unlike ordinary potting silicones, it has excellent adhesion to PC, PP, ABS, PVC and metal surfaces, fast curing speed, and stable performance under temperature cycles, effectively protecting TECs from moisture, dust and external damage, ensuring long-term stable operation for procurement partners.
Key Features & Advantages
- Superior Waterproof & Insulation Performance: Excellent waterproof and sealing effect, effectively isolating moisture and dust to protect TEC internal components; ultra-strong insulation (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), preventing short circuits and ensuring safe operation of thermoelectric coolers.
- Good Thermal Conductivity & Temperature Adaptability: Thermal conductivity ≥0.2 W/(m·K), effectively dissipating heat generated by TEC operation; adaptable to temperature differences of thermoelectric coolers, operating stably in harsh temperature environments, ensuring TEC cooling/heating efficiency is not affected.
- Fast Curing & Easy Operation: Two-component (1:1 weight ratio) design, low viscosity (500±100 cps), easy to mix evenly; fast room-temperature curing (3-5 minutes initial cure, 24 hours full cure), optional vacuum defoaming, improving production efficiency for batch TEC production.
- Strong Adhesion & Flame Retardancy: Excellent adhesion to PC, PP, ABS, PVC and various metals (common in TEC casings), forming a tight seal without detachment; flame retardancy reaches UL94-V1 grade, meeting international safety standards and reducing fire risks.
- Environmental Protection & High Stability: Fully compliant with EU RoHS directive, non-toxic and non-hazardous; low volatility, no stratification after long-term storage (stir before use without affecting performance); mixed glue can be used up at one time, avoiding waste.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A in its container to mix the settled black pigment evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting curing effect and adhesion.
- Mixing: Mix Component A and Component B at a 1:1 weight ratio, stir slowly and evenly to avoid generating air bubbles, which may affect waterproof, insulation and thermal conductivity performance of TECs.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.08MPa for 3 minutes to completely eliminate air bubbles, then pour it into thermoelectric cooler packaging molds or casings.
- Curing: Place the encapsulated TEC at room temperature for curing; initial curing takes 3-5 minutes (enter next process after initial curing), full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed.
