Resistor High-Temperature Potting Solution | SIPC 1813 Silicone Sealant

In applications such as high-power resistors, braking resistors, and power load resistors, SIPC 1813 silicone adhesive sealant is exposed to harsh environments characterized by long-term exposure to high temperatures, high power, thermal cycling, and vibration.The potting material should not only be able to “wrap up” the components, but also not affect the long-term stable operation of the resistor. Application Challenges 🔥 High long-term temperature tolerance requirements: -60 to 250°C Repeated environmental impacts ⚡ High power stability requirements under high temperatures to avoid resistance drift due to stress concentration 🔩 Reliable bonding with substrates such as ceramics, metals, and pins 🌧️ In outdoor or industrial environments, moisture resistance, stain resistance, and anti-aging are required. Recommended product: SIPC 1813 SIPC 1813 is a neutral, semi-flowable RTV silicone adhesive sealant that cures by absorbing moisture at room temperature. It is specifically designed for the long-term stable operation of electronic devices in high-temperature and vibrating environments. Key Performance Advantages✅ – Long-term stability in a wide temperature range of -60 to 260°C, meeting the continuous operation requirements of high-power resistors✅ Excellent adhesion, good compatibility with substrates such as ceramics, resistor coatings, and metal pins✅ Elastic adhesive layer design, effectively relieving thermal stress and avoiding device cracking or resistance drift✅ Resistant to chemicals, moisture, and corona, ensuring long-term reliable electrical performance✅ Resistant to vibration and thermal shock, suitable for industrial, power electronics, and rail transit applications✅ Excellent outdoor aging performance, with a design lifespan of up to 20–30 years✅ ROHS / HF / REACH compliant, environmentally friendly and suitable for mass applicationsTypical Application Scenarios🔹 Power resistor and brake resistor potting🔹 Local sealing of high-temperature electronic modules🔹 Protection of industrial power supplies and power electronics devicesSIPC 1813 is not just “potting”, but also provides a long-term stable safety buffer layer for resistors in high-temperature and high-power environments….
