Bitumen mastic

Bitumen adhesive for roofing felt Den Bit-P (11 kg)

manufacturer: DenBraven | Kods: DNSHDBITP

Bitumen Adhesive for Roofing Felt Den Braven Den Bit-P 

Den Braven Den Bit-P is a high-quality solvent-based bitumen compound, highly modified with synthetic rubber, resins, and specialized chemical additives. The product delivers exceptional elastic properties after solvent evaporation and forms a powerful bond with the substrate. It is designed for the secure bonding of bitumen roofing sheets to the substrate and to each other in multi-layer roofing systems, as well as for installing standalone seamless waterproofing coatings of light, medium, and heavy types.

The formulation is ideal for application on roofs, foundations, and industrial water reservoirs (including wastewater treatment tanks and liquid manure storage pits). The mastic creates highly flexible laminates, which can be reinforced with technical fabrics, and is suitable for bonding rigid polyurethane foam. The product is intended exclusively for outdoor use and requires intensive ventilation of the working area.

Design and Performance Features:

  • High Rubber Modification: The addition of synthetic rubber and specialized resins ensures exceptional substrate bonding and permanent elasticity after full curing.
  • Movement Accommodation: The material's high plasticity successfully accommodates significant substrate shifts and bridges structural microcracks.
  • Chemical and Biological Resistance: The formed coating provides complete resistance to water, weathering, weak acids, alkalis, and aggressive chemical compounds naturally found in soil or industrial effluents.
  • Application Versatility: Suitable for application on completely dry as well as slightly damp mineral and bitumen bases.
  • Material Restriction: Due to its solvent-based composition, the product is strictly incompatible with expanded polystyrene.
