| Epic S7281 is a two component aliphatic polyurethane potting compound designed with a fast cure and convenient 1:1 mix ratio by volume. Due to the low hardness and very low glass transition temperature, S7281 allows expansion and contraction of solder joints and delicate electronic components without causing failures from mechanical stresses. This product also excels in high temperature applications, showing very low weight loss at 125C over extended periods of time. |
