Product Description

RS PRO 195-978 Transparent Yellow Polyurethane Potting Compound is a two-part, flexible encapsulation solution delivered as a convenient twin pack. It is specifically designed for potting and protecting delicate electronic assemblies such as PCBs, ferrites, glass reed switches, and other components exposed to harsh environments. Its low viscosity and clear amber color enable easy application and allow users to visually inspect faults once cured.

This compound mixes easily in the supplied bag, minimizing user contact and simplifying the process. Once cured, it forms a flexible barrier that protects from vibration, mechanical shock, thermal shock, and moisture. The soft cured compound means components can be removed without damaging the unit, making repairs and replacements efficient.

Operating between -60°C and 100°C, this potting compound is ideal for electronics subject to temperature extremes, offering excellent performance at low and high temperatures while maintaining flexibility. Its low water absorption and embedment stress make it suitable for high humidity environments and sensitive circuits where mechanical stress must be minimized.

Applications include potting sensitive electronics in industrial control panels, sensors, automotive circuits, laboratory instruments, and equipment exposed to high humidity and rapid temperature fluctuations. The compound is also RoHS and UL94 compliant, assuring safe use under stringent industry standards.

The included twin-pack system ensures accurate mixing of the polyurethane resin and hardener, separated by a clip for easy combination. The mixture cures fully within 24 hours, allowing a quick operational turnaround for installation and maintenance cycles.
