HYPERDESMO^®-ADY 500 is a fully aliphatic, one component, polyurethane fluid. Upon curing it produces a tough but highly elastic non-yellowing membrane. It contains pigments and special inorganic fillers which result in excellent mechanical, chemical, thermal, UV and natural element resistance properties. Ιt is used as a top-coat to the HYPERDESMO^® System, offering increased UV resistance and colour protection. HYPERDESMO^®-ADY 500 top-coat does NOT yellow or wear out when exposed directly to sunlight (it is aliphatic) even in dark colours, e.g. red.
