Product Introduction
Electrolube PUC is a tough, flexible, modified polyurethane conformal coating specifically designed for the protection of electronic circuitry. It offers excellent mechanical and dielectric properties, ensuring reliable performance in various environments. The coating can be applied via spraying, dipping, or brushing methods, with recommended drying conditions to achieve optimal results.
Enhanced Properties
PUC exhibits high abrasion resistance and solvent resistance even at room temperature curing, making it ideal for robust applications. It features excellent adhesion across a wide temperature range (-55°C to +130°C), protecting against thermal shocks. Additionally, it has a low coefficient of expansion (100ppm), high dielectric strength (60 kV/mm), and meets MIL standards for moisture resistance and thermal cycling. The coating is reworkable using Electrolube CCRG, enhancing its usability in critical electronic assemblies.
Application Scenarios
Electrolube PUC is primarily used for conformal coating on printed circuit boards (PCBs) to protect against environmental hazards such as moisture, dust, chemicals, and temperature fluctuations. Based on TDS, it is suitable for electronic circuitry protection in general applications. Online searches for specific scenarios (e.g., automotive or aerospace) using the exact model PUC yielded no additional verified data; thus, the application is limited to PCB protection as described in the TDS.
