Short Description:

UHE is two component polyurethanes that cure at room temperature to tough rubber-like materials, remaining flexible at temperatures down to even -60°C. UHE adheres to a variety of materials such as metals, concrete, rubber, wood, fiberglass and many others. Due to their low sensitivity to humidity they can also be used for coatings in thin layers and have a remarkably high tensile and tear strength.
