Industries Flourishing with Polyurethane Potting Compounds

Epoxy resin encapsulates capacitorFor industries relying on some form of thermal power, our epoxies are made thermally conductive and thermal-shock resistant. The polyurethane potting compound provides the necessary insulating protection for components, maintaining proper part functionality and sustainability for industries like:

Wind Energy

To work as efficiently as possible, wind turbines require quality polyurethane potting compounds to insulate components like stators and primary motor windings against extreme heat and constant motor rotation. Our resin spread-loads the heat, minimizing the damaging effects occurring over time. As the turbine’s exposure to heat increases, a cheap resin will crack and expand, failing to do its job. Epic Resin’s polyurethane and epoxy potting compounds are made thermal shock-resistant, ensuring they won’t break down or lose their form due to rapid weather changes. Our resins are reliable in any situation.

Solar Energy

Though solar panels are made for prolonged heat exposure, their components still must be protected with our polyurethane potting compound. Made thermally conductive and thermal shock-resistant, our special resin withstands extreme weather conditions, maintaining its shape and chemical structure while protecting vital surface mount technologies and PCB components.
