Weicon Urethane 85, 10800540, 540gm

Weicon Urethanes are two-component polyurethanes that cure at room temperature to tough rubber-like materials. They remain flexible at temperatures down to even -60 Deg.C. Weicon Urethanes adhere to a variety of materials such as metals, concrete, rubber, wood, fibreglass and many others. They are also suitable as flexible coatings in connection with Weicon Plastic Metal (epoxy) systems. 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.
Storage

Store WEICON Urethane at room temperature (+20 Deg.C) in a dry place. Unopened containers can be stored for at least 6 months after delivery at temperatures from +18 Deg.C to +25 Deg.C. Opened containers must be used within 3 months.
