Resinlab® UR3001HP Black Urethane Encapsulant
Categories:	Polymer; Adhesive; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Adhesive
Material Notes:	Resinlab™ UR3001HP Black is a black, two component, room temperature curing urethane encapsulating system. It is designed to cure completely at room temperature. UR3001HP Black provides excellent environmental protection while having tenacious adhesion to various metals, plastics and other common assembly materials. UR3001HP Black is an unfilled system that has a gel-like Shore hardness and good flexibility at temperatures as low as –40°C. It provides excellent moisture resistance and can withstand 125°C continuous operation. UR3001HP Black has a convenient mixing ratio of 1 to 1 by volume. It is well suited to automated meter mix operations. UR3001HP Black is a DOT non-hazardous material and contains no TDI, MOCA, or other reportable substances. Part A is moisture sensitive and must be kept away from atmospheric moisture during storage. After opening a sealed container, thoroughly purge the remaining air space with dry nitrogen (or equivalent) before closing the container.
