Black Silicone Potting Compound For LED Outdoor Lighting
BZ-3701 is a two-component room-temperature-curing condensation-type silicone potting compound exclusively optimized for LED outdoor fixtures and medium-low power LED lighting systems. Featuring a black opaque formulation, wide temperature tolerance (-50~180℃), and compliance with RoHS and halogen-free standards, it provides reliable protection against moisture, dust, and thermal shock for LED drivers, power modules, and control circuits. As a condensation-curing product, its cross-linking reaction requires air moisture participation—critical note: potted fixtures must not be hermetically sealed immediately after pouring, as this will cause incomplete curing.
Key Product Features
Black Opaque Protection: Cures to a deep black finish that effectively blocks light interference, hides internal components, and enhances UV aging resistance, making it ideal for outdoor LED wall washers, underground lights, and floodlights
Cost-Effective Solution: Delivers reliable performance at a competitive price point, optimized for high-volume production of medium-low power LED lighting products
Moisture-Driven Curing: Room-temperature curing via reaction with atmospheric moisture enables simple operation, but requires proper ventilation during the initial curing phase
Wide Temperature Stability: Maintains consistent mechanical and electrical properties across -50℃ to 180℃, withstanding extreme temperature fluctuations in outdoor environments
Eco-Friendly Formulation: Fully compliant with RoHS and halogen-free regulations, supporting sustainable manufacturing practices

Product Applications
LED Outdoor Lighting: Encapsulates drivers and control modules in wall washers, underground lights, floodlights, and streetlights
Medium-Low Power LED Fixtures: Ideal for potting ballast circuits in panel lights, tube lights, and decorative LED lamps
Supporting LED Components: Suitable for low-power power adapters and sensor circuits associated with LED lighting systems (minimal focus on general electronics)
Critical Curing Precautions
BZ-3701 utilizes a condensation curing mechanism that depends on ambient moisture for complete cross-linking:
Avoid Early Hermetic Sealing: Potted assemblies must remain in a well-ventilated environment for at least 24 hours before structural sealing. Premature sealing will trap moisture and prevent full curing, leading to soft spots, poor adhesion, and reduced performance.
Humidity Requirements: Optimal curing occurs at 40%-70% relative humidity. In dry environments, extend curing time or introduce controlled moisture to ensure complete reaction.
Thick Section Potting: For applications requiring potting thickness >3cm, use layered pouring with 2-3 hour intervals between layers to allow moisture penetration and prevent internal curing defects.
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 or with heat assistance (recommended 60°C if needed), according to product and process requirements.
Final Product Confirmation: Perform visual inspection and performance testing as required by the customer.
Packing & Shipping & Storage
Hardener: Typically 5KG/10KG/25KG/200KG metal or plastic drums.
Resin: Typically 25KG/200KG metal or plastic drums.
Store and transport as a general chemical product.
Store sealed, protected from light at room temperature. Shelf life varies from 6 to 12 months depending on packaging; please refer to the expiry date on the shipping package.
When temperature drops to 15°C or lower, the hardener or resin should be stored in a warm place or heated before use for potting. Specific heating recommendations depend on the temperature drop; please communicate and consult with us.
