GrafoTherm - Functional anti-condensation coating

GrafoTherm 20L
DESCRIPTION A one-component, water-borne, functional, anti-condensation coating for airless application.
PRODUCT FEATURES Suitable for interiorpainting of mineral walls and ceilings, such as concrete, plaster, bricks etc.

RECOMMENDED USES Recommended to be used on site for steel roofing sheets, steel structures and other metal surfaces where condensation and dripping water problem occurs.

  The paint is suitable for ceilings The paint is suitable for roofs The paint is matt The paint is water-borne Tool: roller Tool: spray Tool: brush
The coverage of the paint on rough surfaces
The coverage of the paint on smooth surfaces
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).
The product has MED (Marine Equipment Directive) certificate no MED-B-10019 and is thus accepted for painting surfaces inside the ships.

Colour Range White and grey.
Gloss grade Matt

Solids volume 45±2% by volume, 32±2% by weight
Density 1,1 kg/l
Product code 006 5125, 006 5126

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.

Aluminium surfaces: Sweep blast-clean with none-metallic abrasives to an even roughness. (SaS, SFS 5873) If sweep blasting is not possible, the surface should be roughened by hand abrading or washed with MAALIPESU detergent.

Primed surfaces: Industrial coil primer on the backside of the steel roofing 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.

Stainless steel: Roughen the surface by grinding or sweep blasting using non-metallic abrasives.
Priming Temaprime EE, Temacoat RM 40, Temacoat Primer, Temacoat GPL-S Primer, and Rostex Super or directly on galvanized surface (see Surface preparation).

Old painted surfaces are recommended to roughen to ensure adhesion.
Application By airless spray or when not possible by brush or roller. Mix the paint throroughly before use. At spray application the paint can be thinned 0–5%. Airless spay nozzle tip 0.027”–0.029”or bigger and nozzle pressure 150–180 bar. Spray angle max. 400 . Use a spray unit with an output of minimum 2.7 l/min. If sieves should be used, use a course sieve, e.g. 30–60 mesh.
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 to 15 g/litre of paint.
