Fontecryl AP - Water-borne acrylic primer

Fontecryl AP
DESCRIPTION A water-borne, one-component fast-drying acrylic based primer containing active anti-corrosive pigments.
PRODUCT FEATURES Recommended to be used as an anti-corrosive primer on steel, aluminium and zinc surfaces. Suitable also for dipping. Drying times can be shortened by using higher temperatures. Overcoatable also with solvent-borne products.
Recommended uses Steel, aluminium and zinc surfaces.

Colour Range RAL, NCS, SSG, BS, MONICOLOR NOVA and SYMPHONY colours made from FCL base paint. Temaspeed Fonte tinting.

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

Product code 006 5970, -72, -73, -75, -78, 539-series

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 +15ºC during application and drying. Relative humidity of the air should be between 20–70%. 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: 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.

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.
Priming Fontecryl AP.
Finishing Duasolid 50, Temadur SC-F, Fontedur HB 80 and Fontelac QD 80.
Painting For spraying, the product is thinned approximately 0–15%. Recommended nozzle tip is 0.011" – 0.015" ja pressure 120–160 bar. Spray angle shall be chosen according to the shape of the object.

For dip coating, the product is thinned 7–15% to the viscosity 20–25s DIN 4.

Mix the product properly in case of sedimentation or viscosity increase.

Note! The viscosity falls quickly when thinning the paint.
Cleaning of tools Clean the spraying equipment immediately after use as follows:
1. Run the equipment with water to remove excess paint from the equipment.
2. Run the equipment with a mixture of approx 20% Thinner 1109 in clean water, at least two times.
3. Finally wash with undiluted Thinner 1109.

Wash the equipment with water before starting to paint again. Unwashed equipment can cause serious surface defects.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount is 120 g/litre of paint.
VOC content in paint (thinned 15% by volume) is 100 g/l.
