RS PRO Transparent Potting Compound Polyurethane Resin 250 g Optically Clear, Low Viscosity, Cure Time 24 h 146-6593

RS PRO 146-6593 Transparent Potting Compound Polyurethane Resin 250 g is a high-quality optically clear polyurethane resin designed primarily for LED encapsulation and protective applications. Its aliphatic chemical composition provides excellent resistance to yellowing caused by ultraviolet light exposure, making it highly suitable for both indoor and outdoor applications.

The viscous liquid form allows for smooth processing and uniform coating applications. This resin cures within 24 hours at ambient room temperature (23°C) or can be accelerated to 4 hours at 60°C, providing flexibility in manufacturing schedules.

It features a hardness of 75 Shore A, offering a durable yet flexible protective layer. The thermal conductivity of 0.2 W/mK helps manage heat dissipation in electronic assemblies, while the product's volume resistivity of 10^14 Ω cm and dielectric strength of 11 kV/mm ensure reliable electrical insulation.

Operating temperature tolerances from -40°C to 120°C broaden the product’s usability across various industrial and commercial environments, including mechanical, electronic, and fluid power industries. It is resistant to acids, alkalis, moisture, mould growth, UV light, weathering, and physical abrasion, ensuring longevity and reliability in demanding conditions.

This potting compound complies with international standards such as RoHS and ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007, highlighting its suitability for electrostatic discharge (ESD) sensitive applications. It's ideal for industrial LED lighting, outdoor lighting fixtures, and other protective electronic encapsulations.

The compound features water-white transparency and low viscosity for ease of processing. Cure time is 24 hours at room temperature, or 4 hours at elevated temperature. Excellent resistance to UV-induced yellowing ensures long-term clarity.

Resistant to chemical agents such as acids and alkalis, as well as mould and weathering. Thermal conductivity supports heat management in electronic assemblies. High volume resistivity and dielectric strength provide superior electrical insulation.

Compliant with RoHS and multiple ESD standards for environmental and safety assurance.
