Proofab Bitumen Sealant 911
Flexible Sealant with High Adhesion Strength
Description
PROOFAB Bitumen Sealant is a high-performance product based on reprocessed bitumen, emulsion resins, specialized additives, and petroleum-based solvents. It is packaged in special cartridges and applied using a sealant gun for injecting into cracks and joints. This product is a bitumen-based adhesive designed for sealing and waterproofing various joints on metal, cement, or asbestos roofing. It offers exceptional resistance to water and moisture.
Due to its high density, PROOFAB Bitumen Sealant can be used on vertical, sloped, and horizontal surfaces. Compared to putty application, it offers a much easier and more efficient installation due to its cartridge packaging and application with a dedicated gun.
Performance Mechanism
This product exhibits excellent adhesion to substrates. Its density allows it to effectively fill cracks and joints. The presence of emulsion resins and modified bitumen in its formulation provides high elasticity and flexibility, ensuring good resistance to minor structural movements.
Applications
- Repairing cracks and joints in asphalt surfaces
- Sealing and waterproofing cement and asbestos surfaces, as well as metal roofing sheets
- Sealing and waterproofing screw holes on roofing structures
- Suitable for use as an internal seam sealer in vehicle bodies
- Sealing pipe joints, tanks, and similar applications
- Sealing and repairing cracks and joints on concrete and cement surfaces
- Suitable for sealing around chimneys
- Adhering lifted edges of bitumen membranes (IsoGum)
- Repairing damaged waterproofing layers (bitumen membranes and tar-based coatings)
