Product Overview
Our Outdoor Lighting Electronic Potting Silicone Compound is a professional potting material tailored for outdoor lighting fixtures, a key part of HONG YE SILICONE’s full silicone product matrix. Model HY-9325 is a low-viscosity, two-component room-temperature vulcanizing silicone, also called encapsulation silicone or electronic silicone. It is designed to solve outdoor lighting pain points—rain, UV radiation, temperature extremes and dust, curing into a dense protective layer to form a reliable waterproof and insulation system, ensuring long-term stable operation of outdoor lighting components, far exceeding ordinary Electronic Potting Compound in outdoor adaptability. Product Features & Advantages
1. Outdoor-specific waterproof & dustproof: Excellent waterproof performance, forming a seamless seal to prevent rain, dew and dust from entering outdoor lighting fixtures, avoiding short circuits and component damage, adapting to various outdoor environments.
2. UV resistance & weather aging resistance: Effectively resists outdoor UV radiation and weather erosion, no yellowing or cracking after long-term exposure, maintaining stable performance and extending the service life of outdoor lighting fixtures.
3. Wide temperature adaptability: Operates stably in extreme outdoor temperatures, paired with excellent insulation (volume resistivity ≥1.0×10¹⁶ Ω·cm, dielectric strength ≥25 kv/mm) and UL94-V1 flame retardancy, ensuring safe operation in harsh outdoor conditions.
4. Easy operation & production-friendly: 1:1 weight mixing ratio (easy to measure), low viscosity with good fluidity; optional deaeration at 0.08MPa for 3 minutes ensures bubble-free potting, suitable for automated outdoor lighting production lines.
5. Strong adhesion & customization: Excellent adhesion to PC, PP, ABS, PVC and metals, firmly fixing outdoor lighting components; key parameters (hardness, viscosity, operable time) can be customized to match different lighting fixture types.
Technical Specifications (Model HY-9325)
This product is a two-component outdoor lighting potting silicone, with Component A and B both being viscous liquids; Component A has a viscosity of 500±100 cps. The mixing ratio is 1:1 by weight, operable time is 30-120 minutes, initial curing time 3-5 minutes, full curing time 24 hours (affected by ambient temperature and humidity). After curing, it reaches Shore A hardness 25±2, thermal conductivity ≥0.2 W(m·K), dielectric strength ≥25 kv/mm, dielectric constant 3.0～3.3 (1.2MHz), volume resistivity ≥1.0×10¹⁶ Ω·cm, UL94-V1 flame retardancy. Other models and customizable parameters are available on request.
How to Use
1. Preparation: Fully stir Component A to mix settled black pigment evenly; shake Component B thoroughly to ensure uniform material composition without stratification, critical for outdoor waterproof and UV resistance performance.
2. Mixing: Blend Component A and B strictly according to 1:1 weight ratio, stir thoroughly to guarantee consistent waterproof, insulation and curing performance for outdoor lighting components.
3. Deaeration (Optional): Place the mixed liquid into a vacuum container, deaerate for 3 minutes under 0.08MPa to remove air bubbles, ensuring a dense, bubble-free protective layer for outdoor use.
4. Potting & Curing: Pour the treated silicone onto outdoor lighting components (circuit boards, modules); cure at room temperature, proceed to the next process after initial curing, and ensure 24 hours for full curing to achieve optimal outdoor protection.
Application Scenarios
Widely used for potting, insulation, sealing and fixing of outdoor lighting electronic components, including outdoor LED displays, LED street lights, garden lights, flood lights, billboard lights and outdoor lighting junction boxes. It adheres well to PC, PP, metals and other outdoor lighting substrates, protecting components from rain, dust, UV radiation and temperature changes. It reduces outdoor lighting failure rates and after-sales costs, enhancing product durability and market competitiveness for outdoor lighting manufacturers.
