SIPC 2130 silicone adhesive sealant | underwater LED sealing solution-Elaplus functional Materials Co., LTD

Home » Industry Application » Details

Long-term waterproof bonding solution for glass × aluminum structure: In applications such as underwater LED lights, landscape lighting, pool lights, fountain lights, and buried lights, seal failure equals lamp failure.

Especially for glass and aluminum structures, not only are there significant material differences and different coefficients of thermal expansion, but they also have to face the following challenges over the long term:
💧 Water pressure infiltration

🌡️ Cold and heat cycling

⚡ Electrical safety and insulation requirements

👀 High demands on appearance transparency pose extreme challenges for sealants.
Analysis of core adhesive needs

✔ Reliable bonding between glass and aluminum

✔ Waterproof and effective for long-term underwater use

✔ Transparent and clear adhesive, without affecting light efficiency

✔ No corrosion to base materials, no yellowing, no oil leakage

✔ Stable performance in high-temperature and high-humidity environments

Recommended solution: SIPC 2130 transparent silicone adhesive sealant
RTV SIPC 2130 is a neutral curing, transparent silicone adhesive sealant specifically designed for LED sealing and electronic protection scenarios, balancing reliability and aesthetic performance.
Why is SIPC 2130 particularly suitable for LED sealing?
🔹 It is a neutral curing system friendly to glass and aluminum bonding, with no corrosion risk to metals and glass, and it remains stable and does not fall off over a long period of time.
🔹 With its excellent waterproof and sealing performance, it forms a continuous, dense, and elastic sealing layer, making it suitable for long-term use underwater or in high humidity environments.
🔹 High transparency, with no impact on light efficiency. After curing, the colloid is clear and transparent, without yellowing, fogging, or oil leakage, making it ideal for visible areas.
🔹 Excellent environmental resistance
Temperature range: -60 to 220℃. Resistant to high temperature and humidity, with long-term stable electrical properties. Resistant to engine oil, transformer oil, acids, and alkalis. 🔹 Reliable electrical and mechanical protection
Excellent insulation performance, moisture-proof, dust-proof, anti-corona, shock-resistant and cushioning, protecting LED solder joints and circuits 🔹 Long service life, excellent aging resistance, with a design lifespan of up to 20 to 30 years, suitable for maintenance-free lighting design.
🔹 Low viscosity, easy to apply and flow smoothly, suitable for various processes such as potting, dispensing, and sealing.
