Cost-Efficient Transparent Silicone Potting Compound for Basic Electronic Protection
High-Transparency Silicone Potting Compound For LED Lighting
BZ-3703 is an economical two-component room-temperature-curing condensation-type silicone potting compound exclusively designed for basic LED lighting products and low-power electronic devices. Featuring moderate transparency, wide temperature tolerance (-50~180℃), and RoHS compliance, it provides reliable protection against UV radiation, thermal shock, and moisture for standard components. However, its performance is constrained by basic electrical insulation (breakdown voltage ≥15 kV/mm) and limited thermal conductivity, making it unsuitable for high-power systems, extreme environments, or precision electronic applications.
Key Product Features
- Cost-optimized solution: Delivers reliable performance at a competitive price point, ideal for high-volume production of entry-level LED lighting and consumer electronics
- Simplified operational workflow: Excellent fluidity and a 10:1 mixing ratio (A:B) enable straightforward pouring and potting operations with minimal training
- Balanced thermal stability: Maintains consistent performance across -50 to 180℃, withstanding typical temperature fluctuations in residential and commercial environments
- High-clarity encapsulation: Preserves strong light transmittance, suitable for standard LED modules and basic optical assemblies
- Adequate UV resistance: Offers reliable defense against ultraviolet degradation in non-extreme outdoor applications
- RoHS-compliant formulation: Meets EU RoHS directives, supporting eco-friendly manufacturing practices
- IPX7 waterproofing: Ensures sealed components remain functional in wet conditions, ideal for general outdoor lighting and portable devices

Directions for Use
- Pre-potting Preparation: Calibrate scales, prepare potting tools, cleaning tools, check machine settings, check vacuum pump force, etc.
- Product Pre-treatment: Place product on a level surface or fixture. Remove dust, clean, degrease, and dry if necessary.
- Accurate Proportioning: Manual operation requires precise mixing according to the specified ratio and recording. Machine potting requires calibrated ratios and first-article confirmation is recommended.
- Mixing & Stirring: Manual operation requires thorough stirring or using electric stirrers to ensure homogeneous mixing. Machine potting requires sufficient stirring speed, adjust as needed.
- Uniform Potting: Manual operation should be done in small, multiple batches to ensure uniformity. Machine potting should follow the programmed path for quantitative dispensing.
- Inspection or Secondary Potting: After potting, visually inspect as needed. Perform touch-up, bubble removal, or secondary potting if required.
- Curing: Allow the potted and inspected products to cure at room temperature , according to product and process requirements.
- Final Product Confirmation: Perform visual inspection and performance testing as required by the customer.
