Tikkurila Temabond ST 300 is a two-component high-solids, modified tintable epoxy maintenance paint for demanding surfaces. It is an ideal solution for maintenance painting due to its very good adhesion even to hand-prepared steel. As a high-solids product, the paint has lower VOC emissions than conventional epoxy paints.

Temabond ST 300 withstands immersion in water and can therefore be used e.g. on steel structures immersed in water or buried in soil. The product can also be used for painting hydro-power stations. As a CE-marked product, Temabond ST 300 is suitable for concrete surfaces.

The tintable Temabond ST 300 forms a very tight film with good chemical and abrasion resistance. The product is used for repainting and touch-up painting steel surfaces that are difficult to clean, such as bridges, cisterns and different types of steelwork and equipment in the wood-processing and chemical industries.

Temabond ST 300 mastic paint has the ability to penetrate rust and adhere to the underlying steel surface, effectively preventing further corrosion.

Technical Data

Volume Solids: 80±2% (ISO 3233)

Weight Solids: 88±2%

Specific Gravity: 1.5 kg / l (mixed)

Mixing Ratio:

• Base - 1 part by volume - Temabond ST 300
• Hardener - 1 part by volume - 008 7501

Surface 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.

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.

Note! There is a natural tendency of this coating to chalk, discolor or yellow unevenly. It is recommended to use polyurethane topcoat when there are high aesthetical requirements on colour appearance.

Mixing 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.

Application

• 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 product should be thinned according to the circumstances.
