FREE MASTIC DN-520

DN-520 was developed on the new concept of polymer alloy utilizing IPN(Interpenetrating polymer network) effect and this new polymer structure exhibits very unique characters like below. Applied on the rusted surface directly SSPC-SP2 (removing scales with hammer, wire brushing for heavy rust) wire brushing for light rust] no need of sand blasting good affinity to rust Can be applied to even water wetted rusted surface Can be applied to even oil wetted rusted surface  light mineral oil sometimes oil is used on purpose Applied on wetted, mineral oil contaminated steel plate directly Applied on mill scale Applied on stainless steel Applied on wetted concrete                                                           Application Example                           INDIA - Hindustan Petroleum Storage Tank                     before application                                          after application                     KOREA – Water Treatment (Drinking Water)
