Product Description
PROOF RC 1K is thixotropic. It adheres very strongly to almost any type of surface, including bituminous substrates, forming a hydrophobic and elastic film.
Its resistance to chemicals and mechanical effects is excellent.
Ideal for vertical surface applications; it does not sag or blister.
It is based entirely on elastomeric hydrophobic polyurethane resin, supplemented with chemically polymerised pure bitumen.
Application Areas
- Gypsum and cement panels
- Asphalt membranes (also suitable for repair)
- Cement-based substrates, roofs
- Lightweight roofs made of metal or fibre cement
- Floors, foundations
Advantages
- Its elasticity is 1000%.
- Thixotropic: it can be applied easily on vertical or sloped substrates and on surfaces with complicated details, without sagging or blistering.
- Cures quickly.
- Adheres perfectly to almost any type of surface, with or without a primer.
- Although it does not require thinning, SOLVENT can be used depending on the conditions.
- Thermal resistance is excellent; the product never softens. Maximum service temperature is 80 °C, maximum shock temperature is 150 °C.
- Resistant to cold: the film retains its elasticity down to -40 °C.
- Has superior mechanical properties: high elongation capacity, tensile, tear and abrasion strength.
- Chemical resistance is excellent.
- Functions effectively as a moisture barrier.
Application
In general, it adheres perfectly to almost all types of substrates, including bituminous surfaces, without the need for a primer. However, carrying out a test before starting the application is strongly recommended.
