ELAN-Tron® U 510S-6 Black Thixo / UH 510S is a two-component, 100% solids polyurethane potting compound designed for electrical and electronic equipment. It cures at room or low temperature, offers excellent adhesion to plastics and metals, and remains flexible down to -40°C and below. The thixotropic nature enables controlled application without sagging. It demonstrates strong resistance to hydrolysis (85°C / 85% R.H.), good thermal shock resistance, and is suitable for Class 120 service.
