The sealant that bonds to bitumen
Thanks to its special formulation, 390 Spengler is an ideal fit for expansion and perimeter joints on roofs. The acrylate bonds flawlessly to metal, wood and concrete without the need for primer. Thanks to its formulation, which includes solvent and is silicone-free, it can also be used on mildly oily or damp substrates. The elastic sealant applies effectively, can be covered with different paint coats and can also be used with bitumen.
