About Tikkurila Temacoat RM 40, Semi-Gloss Modified Epoxy
Tikkurila Temacoat RM 40 is a very versatile and tough, abrasive resistant coating for steel and concrete in wet and chemically stressed environments.
It has excellent adhesion can be used as a universal primer, a single-coat paint and a topcoat for application to steel, zinc and aluminium and concrete surfaces.
It is ideal for steel structures in wet environment, e.g. inside pontoons, ballast water tanks, ship hulls and underground / underwater applications and surfaces exposed to severe splashing.
It is not suitable for swimming pools.
Resistant to grey/waste water when applied 2x125µm.
Recommended for building frameworks, tubular bridges, conveyors, ship hulls and other steelwork and equipment.
Preparation
Ensure any loose material oil, grease, salts and dirt are removed.
Steel surfaces: Blast clean to grade Sa2½. (ISO 8501-1)
If blast cleaning is not possible, phosphating is recommended for cold rolled steel to improve adhesion.
Zinc surfaces: Sweep blast clean with mineral abrasives, e.g. quartz sand, to an even roughness.
If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with Panssaripesu detergent. For hot dip galvanized surfaces see separate application instructions or contact the Technical Service department.
Aluminium surfaces: Sweep blast clean with non-metallic abrasives to an even roughness. If sweep blasting is not possible, the surface should be lightly abraded or washed with Maalipesu detergent.
Primed surfaces: Remove any oil, grease, salt and dirt are removed by using a cleaner degreaser and lightly abrade.
Concrete surfaces: The surface must dry and at least 4 weeks old.
The relative humidity of the concrete should not exceed 97%.
Remove any splashes and unevenness by grinding.
Remove laitance and form oil from concrete castings by sanding or blast cleaning.
Application
All surfaces must be clean, dry and free from contamination.
The temperature of the ambient air and surface should not fall below +5ºC during application and drying.
Relative humidity of the air should not exceed 80% during application and drying.
The surface temperature of steel should remain at least 3°C above the dew point.
For proper application the temperature of the product itself should be above +15°C during mixing and application.
Good ventilation and sufficient air movement is required in confined areas during application and drying.
Note! There is a natural tendency of this coating to chalk, discolour or yellow unevenly. It is recommended to use polyurethane topcoat when there are high aesthetical
requirements on colour appearance.
For airless spraying, the product is thinned approximately to a maximum of 20% by volume.
Recommended nozzle tip is 0.015"–0.021" and pressure 120–180 bar.
For brush application (small areas) the product should be thinned as required
Thinners: Thinner 1031
Cleaning of Equipment: Thinner 1031
VOC: 430 g/litre when thinned.
Volume solids : 63-65%
For Drying and curing times please refer to the datasheet.
