GrafoTherm Line - Functional anti-condensation coating

GrafoTherm Line
DESCRIPTION A one-component water-borne anti-condensation coating for line application.
Recommended uses Recommended to be used for steel roofing sheets for interior and sheltered premises.

Features Excellent moisture absorbing and evaporation properties.
Prevents from condensation and dripping water, insulates from heat (λ= 0.085 W/mK).
Forms very elastic and porous coating layer.
Provides also vibration and acoustic damping when applied as a thick layer.
Complies with the requirements of EN13501-1, class A2-s1d0 and ASTM E84 (USA).

Colour Range White and grey.
Gloss groups Matt

250–500 g/m2

600–1200 g/m2

1.8–0.9 m2/l

Recommended coverage depends on the ambient conditions like moisture and type of
building etc.
See separate Grafotherm Treatment Programme.
Practical coverage depends on the application method, painting conditions and the shape
and roughness of the surface to be coated.

Drying and recoating times are related to the film thickness, temperature, the relative
humidity of the air and ventilation.

Water absorption approx. 330g/m2 of water, 600 g/m2 WFT (250g/m2 DFT), (NF P15-203-11997)

Product code 006 5123, 006 5124

Application conditions All surfaces must be dry. The temperature of the ambient air and surface should not fall
below +10ºC during application and drying. Relative humidity should not exceed
80%. The surface temperature of the surface to be coated should remain at least 3ºC
above the dew point.
The temperature of paint itself should be above +15°C for proper application.
Good ventilation is required in confined areas during application and drying.
Preparation Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)

Zinc and aluzinc surfaces: Sweep blast-clean with mineral abrasives, e.g. quartz sand,
to an even roughness. (SaS, SFS 5873) If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with PANSSARIPESU detergent.

Primed surfaces: Industrial coil primer on the backside of the steel roofing sheets does
not require any special preparation. Grease, salt and dirt are removed from the surface
by appropriate means. Repair any damage to the primer coat with Temaprime EE or
Rostex Super. Note the overcoating time of primer.
Priming Industrial coil sheet backside primer. Can be applied directly on galvanized thin steel (see Surface preparation).
Application Conventional spraying or plaster spray gun. Mix the paint thoroughly before use.
The paint can be thinned 0–5% by volume. Spray nozzle tip 6mm and nozzle pressure
2 bar. Air supply >1000 l/min (conventional spraying) and >250 l/min (plaster spray
Finishing Do not overcoat with any other type of coating as it causes loss of absorbing properties.
Cleaning of tools Water.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount is < 3 g/litre of paint mixture.
