Coverage

Recommended film thicknesses Theoretical coverage
dry wet
80 µm 120 µm 8.4 m2/l
150 µm 225 µm 4.4 m2/l

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

Drying times

DFT 100 um 0 °C + 10 °C + 23 °C + 35 °C
Dust dry, after 16 h 4 h 2 h 1 h
Touch dry, after 24 h 10 h 4 h 2 h
Recoatable, min. after 24 h 3 h 1 h ½ h
Recoatable, surfaces to be submerged, after 4 d 28 h 12 h 6 h
Recoatable with polyurethane paints, after 1 d 5 h 2 h 1 h

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

Application details

Application conditions

All surfaces must be clean and dry and free from contamination. The temperature of the substrate should be minimum +0°C and at least 3°C above the dew point of the air. The product should not be applied at temperatures below 0°C where there is a possibility of ice formation on the substrate. The temperature of paint itself should be above + 15 °C for proper application. Good ventilation is required in confined areas during application and drying.

Note! There is a natural tendency of epoxy coatings to chalk and discolor on exterior exposure.

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.

Hot dip galvanized surfaces are recommended to be painted with a mist coat (paint thinned 25 - 30 %) before the actual priming.

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)

Priming

Temacoat SPA Primer, Temazinc 77, Temazinc 88 and Temazinc 99.

Finishing

Temacoat HB 30, Temacoat GPL, Temacoat GS 50, Temacoat GPL-S MIO, Temacoat SPA 50, Temadur and Temathane.

Painting

By airless spray or brush. At spray application the paint should be thinned 0 - 10 % by volume. Airless spray nozzle tip 0.015" - 0.021" and nozzle pressure 120 - 180 bar. Spray angle shall be chosen according to the shape of the object. At brush application the paint 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 Temaspeed Squirrel Mixer for mixing.
