Temabond ST 300 - High-solids epoxy paint

 
Temabond ST300
DESCRIPTION A two-component high-solids, modified epoxy paint.
PRODUCT FEATURES Especially used as a primer for steel surfaces difficult to clean in process and chemical industry and in water immersion. Recommended for repairing of damages caused by transport or installation. Can also be applied on old alkyd paint surfaces. Can be used as a single coat paint.
Recommended uses Steel surfaces.

TECHNICAL DATA
Features Forms a tight coat with good chemical and abrasion resistance.
High film build properties, also by brush.
Very good adhesion to blast cleaned or hand prepared steel.
Low solvent content, lower solvent emissions than with traditional epoxy paints.

APPLICATION DETAILS
Application conditions All surfaces must be clean, dry and free from contamination. The temperature of the ambient air, surface and paint should not fall below +10ºC 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. Good ventilation and sufficient air movement is required in confined areas during application and drying.
Preparation Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)

Steel surfaces: Remove rust by tool cleaning to minimum St2 or blast clean to Sa2 or Sa2½ . Blast clean to grade Sa2½ for immersion. (ISO 8501-1)

Earlier painted surfaces: Roughen old paint surfaces using e.g. abrasive wheel, sand paper or blast cleaning.

Concrete surfaces: The surface must be dry and at least 4 weeks old. The relative humidity of the concrete should not exceed 97%. Remove any splashes and unevennesses by grinding. Remove laitance and form oil from concrete castings by sanding or blast cleaning. Any cracks, crevices and voids must be repaired with a mixture of Temafloor 200 and fine dry quartz sand.

Painting For airless spraying, the product is thinned approximately 0–10%. Recommended nozzle tip is 0.013"–0.019" and pressure 120–180 bar. Spray angle shall be chosen according to the shape of the object.

For brush application the product should be thinned according to the circumstancies.
Mixing of components First stir base and hardener separately. The correct proportions of base and hardener must be mixed thoroughly before use. Use power mixer for mixing. Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface and weaken the properties of the coating.
Cleaning of tools Thinner 1031.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount is 195 g/litre of paint mixture.
VOC content of the paint mixture (thinned 10% by volume) is 260 g/l.

For industrial and professional use only.
