Tikkurila Temacoat Primer is a two-component resin modified epoxy paint containing anti-corrosive pigments that adheres well to steel, zinc and aluminium surfaces, ensuring a long service life for paint systems in severe environments.

The high-build primer can be applied at sub-zero temperatures and is used as a primer or an intermediate coat on surfaces exposed to climatic, mechanical and chemical stress.

The product is used as an intermediate coat in the NORSOK approved systems on surfaces exposed to marine conditions, and is recommended for building frameworks, tubular bridges, conveyors and other steelwork and equipment.

Fast & low-temperature curing hardener (008 5613) available on request; contact our sales team on 0113 2455450 or [email protected] to discuss your project requirements.

Case Studies

The steel structures of the world’s largest indoor ski centre in Norway are manufactured by Ruukki and protected with Tikkurila's polyurethane system TP131, which consists of anti-corrosive Temacoat Primer and high-solids polyurethane topcoat Temathane PC 50. The combination provides excellent weather and abrasion resistance for steel, stainless steel, aluminum and zinc surfaces.

Under construction at Lørenskog, Norway (approx. 20km east of Oslo), six-story skiing complex is the world's largest indoor ski center with a snow-covered area of around 40,000 square meters (the equivalent of five football pitches) comprising of a 500m long downhill ski slope, equipped with three ski lifts, and a cross-country ski track suspended from the ceiling with 150 components and weighs about 500 tonnes.

The steel structures are coated with Tikkurila's polyurethane system TP131. Quality standards for the ski center's steel structures and protective coatings are very high; the minimum structural steel grade was S355, but certain structures of longer span distances required S550 high-strength steels. Protective coatings had to meet corrosion class C3 H according to EN-12944.

Recommended Film Thicknesses and Theoretical Coverage

Practical coverage depends on the application method, painting conditions and the shape and roughness of the surface to be coated.

Drying Times

Fast & low-temperature curing hardener (008 5613) available on request; contact our sales team on 0113 2455450 or [email protected] to discuss your project requirements.

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

Surface Preparation

Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)

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. (SaS, SFS 5873)
• 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 Tikkurila Technical Service/Rawlins Technical on 0113 2455450 (option 2) or send a message to [email protected]

Aluminium surfaces:

• Sweep blast clean with non-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:

• Oil, grease, salt and dirt are removed from the surface by appropriate means.
• Repair any damage to the primer coat.
• Note the overcoating time of primer. (ISO 12944-4)

Application Conditions

With hardener 008 5611:

• All surfaces must be clean, dry and free from contamination.
• During application and drying the temperature of the surface should not fall below 0°C.
• The surface temperature of steel should remain at least 3°C above the dew point.
• Relative humidity of the air should not exceed 80% during application and drying.
• The product should not be applied at temperatures below 0°C when there is a possibility of ice formation on the substrate.
• 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.

With hardener 008 5613:

Hardener (008 5613) available on request; contact our sales team on 0113 2455450 or [email protected] to discuss your project requirements.

• All surfaces must be clean, dry and free from contamination.
• During application and drying the temperature of the surface should not fall below -10°C.
• The surface temperature of steel should remain at least 3°C above the dew point.
• Care has to be taken that there is no ice on the substrate.
• 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, 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 0.015"–0.021" 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.

Thinners & Cleaners

• Thinner 1031

For cleaning, use Thinner 006 1031.
