ARADUR® 3985

ARADUR® 3985 epoxy curing agent can be used to formulate self-leveling as well as highly filled flooring systems, which can be applied up to several millimeters thick. Such formulations show a visible end of pot life and exhibit very good adhesion to concrete and metallic substrates. It can also be used as a modifier for other waterborne curing agents that do not provide a visible end of pot life. When combined with liquid epoxy resins, ARADUR® 3985 can formulate fast-drying and curing films, even in cold (~10°C) and humid environments, provided adequate ventilation is available. Coatings and floorings based on ARADUR® 3985 are suitable for decorative applications (e.g., exhibition areas) due to their low color and good color stability.
