Ramsauer 390 Spengler – Bitumen-compatible sealant for roofs and walls

Ramsauer 390 Spengler is a powerful, solvent-based sealant developed specifically for demanding seals in roof and wall areas. Thanks to its special formulation, the sealant adheres even without priming to numerous substrates such as glass, wood, concrete, metal and many plastics.

A particular strength of 390 Spengler is its excellent bitumen compatibility. This makes the sealant optimally suited to applications in the plumbing and roofing sector. The material also offers reliable adhesion on damp and slightly oily substrates, enabling particularly versatile application.

After full curing, Ramsauer 390 Spengler impresses with its crystal-clear appearance. The sealant is also particularly UV- and weather-resistant, non-corrosive and can be painted over with different paint systems. This makes it a reliable solution for durable expansion and connection joints indoors and outdoors.
