Bergolin 2C FlexSeal 6D4500
Description
Bergolin 2C FlexSeal 6D4500 is a highly flexible, solvent-free, two-component polyurethane filler designed for a wide range of applications on mineral and metallic substrates. The material bridges cracks and forms a durable, resilient, and well-adhering surface—ideal for leveling and protecting high-traffic areas. Its fast-curing, solvent-free formulation allows for efficient work even in emission-sensitive environments. FlexSeal is suitable for both indoor and outdoor use and delivers reliable performance even under demanding conditions.
