UR5097 Black Polyurethane Resin
In Stock
This thermally conductive Polyurethane encapsulation and potting compound is a two part system with a black finish. It exhibits excellent thermal conductivity making it ideal for applications where heat dissipation is required.
The cured polyurethane is resistant to a wide or cycling temperature range making it an ideal choice for applications where thermal shock is a potential risk to the electronics, while it is also flame retardant to UL94 certification.
