Tikkurila Temacoat SPA Primer is a two-component resin modified epoxy primer with anti-corrosive pigments with excellent adhesion to steel, zinc and aluminium surfaces. It can be applied in thick layers, thus enabling faster production.

Used as a primer or an intermediate coat in paint systems exposed to abrasion and chemical stress; recommended for building frameworks, tubular bridges, conveyors and other steelwork and equipment.

For industrial and professional use only.

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

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

• 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.
• For proper application the temperature of the product itself should be above +15°C during mixing and application.
• 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.

Note! There is a natural tendency of this coating to chalk, discolour 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.
