S7633: Advanced UL 94 V-0 Potting Compound for Electrical Applications

S7633 is a two-component polyurethane potting compound developed to deliver excellent thermal stability, mechanical protection, and fire safety for today’s high-demand electrical and electronic systems. Its formulation is optimized to provide long-term reliability under elevated temperatures and challenging environments.

Key Features

  • UL 94 V-0 Flammability Rating – Achieves V-0 classification at 9 mm thickness, ensuring superior fire resistance for sensitive electronics.

  • High Thermal Endurance – Designed for an RTI (Relative Thermal Index) rating >140°C, making it suitable for continuous operation under high thermal loads.

  • Low CTE & Low Tg – Offers an optimal balance of low coefficient of thermal expansion (CTE) and low glass transition temperature (Tg), reducing mechanical stress on components and improving dimensional stability.

  • Robust Protection – Safeguards electronics against moisture, dust, vibration, and mechanical impact.

Typical Applications

S7633 is tailored for use in applications where safety, durability, and performance are critical, including:

  • Battery Packs – Provides superior protection against heat buildup and mechanical stress, enhancing safety and extending service life.

  • Electrical & Power Devices – Ensures reliable insulation and structural integrity for converters, controllers, and other high-performance systems.

With its unique combination of high flammability resistance, thermal endurance, and mechanical stability, S7633 is the ideal choice for manufacturers seeking to improve the reliability and safety of battery packs and other critical electrical applications.
