Black bituminous paint
ravenol is a solvent-borne bituminous based coating.
Uses:
- Protective coating for metallic and cementitious surfaces
- Suitable for drinking water tanks and piping
- Protective coating for vehicle chassis
Advantages
- Economical
- Provides protection
- Easy to apply
Surface Preparation
Any surface to which ravenol is to be applied must be clean, mechanically sound and dry. Surfaces should be free of oil, grease, loose material and old paint.gs.
Bonding / Priming
No priming required.
Mixing
Stir well before use. For spray application through conventional equipment, some 10 – 15% by volume dilution with white spirits or turpentine substitute will be needed. If used in a dipping bath, the viscosity should be reduced to some 20 sec BSB4.
Coverage
Practical coverage for estimating purposes: 8 m2/L depending upon surface texture and porosity. Where ravenol is applied to concrete 5°C to 40°C or other cementitious surfaces, the coverage will depend upon the porosity of the surface but will probably average about 4 m2/L.

Application
Application by brush, spray or dip. ravenol may be applied directly from the can. If used in a dipping bath, the bath should be as narrow as possible to present minimum surface area to the atmosphere and thus reduce volatile loss.
ravenol has limited corrosion inhibitive properties when applied to iron or steel.
Note: Minimum requirements for airless application – 23:1 airless pump such as the Graco Monarch with 5-6 bar inlet air pressure.
Cleaning
Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe® super brush cleaner followed by washing with soap and water.
Temperature & Relative Humidity
Application temperature range: 5°C to 40°C
Model Specification

The coating will be ravenol, a one component, solvent-based, coating applied in accordance with the recommendations of a.b.e.® Construction Chemicals. The coating will have a density of 0,92 g/cm3.
Packaging
1L, 5L and 25L containers.
Handling & Storage
This product has a shelf life of 24 months from date of manufacture if kept in a dry cool place in the original packaging and under cover. In more extreme conditions this period might be shortened.
Health & Safety
Fire resistance of wet material: Flammable.
Toxicity: Solvents are toxic.
Ventilate working area well during application and drying. Avoid flames in vicinity. Always wear gloves when working with the material and avoid excessive inhalation and skin contact. If material is splashed in the eye, wash with plenty of clean water and seek medical attention.
Cured ravenol is inert and harmless.
