Axalta N4700 Two Pack Yellow Etch Primer is a modified-vinyl zinc chromate etch primer for steel and non-ferrous metals.
Axalta N4700 Two Pack Yellow Etch Primer is formulated as an adhesion promoter for ferrous and non-ferrous metals, particularly aluminium. Contains zinc chromate.
Carbon Steel Preparation - (non-blasted): thoroughly degrease and prepare to St2 (ISO 8501-1:2007) taking care to avoid ‘polishing’ the surface.
Galvanised Steel Preparation - thoroughly degrease using a propriety biodegradable degreaser, rinse with clean fresh water and allow to dry before coating. It is essential to remove all flux, zinc salts and high profile zinc spatter. Very smooth or glossy areas should be lightly abraded to provide a ‘key’
Aluminium, Copper, Brass, Cadmium and Nickel Preparation: thoroughly degrease using a propriety biodegradable degreaser to remove all verdigris, salts and other contaminants. Wash with clean fresh water and allow to dry. Very smooth or glossy areas should be lightly abraded to provide a ‘key’.
All surfaces to be coated should be dry and cleaned as necessary to remove all oil, grease, salts, weld flux or other contamination. Where necessary, remove weld spatter and grind smooth all sharp edges and weld seams.
Mix only in the proportions stated, mixing each component individually then together using a mechanical agitator. Agitate periodically during use to ensure product remains homogeneous. Mixed material must be discarded after 8 hours at 23ºC.
Only apply in conditions of good ventilation which must be maintained during drying and curing. Do not apply when rain, mist, sleet or snow are imminent. During application and drying time of the coating, the surface should be dry, the Relative Humidity should not exceed 85% and the substrate temperature should remain at least 3ºC above the dew point. Only apply this product when the above conditions can be maintained throughout the critical application and drying/curing process. Paint temperature should ideally be at a minimum of 15ºC.
