Product Specification

Drying Times

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

Surface Preparation

Carbon Steel (Non-Blasted)

• Thoroughly degrease and prepare to St2 (ISO 8501- 1:2007) taking care to avoid ‘polishing’ the surface

Non-Ferrous Metals

• 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’

General

• 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

Application Methods

• This product would normally be spray applied, with conventional spray preferred, as airless spray may result in over-application
• DO NOT OVER APPLY or splitting of primer by topcoats may result
• Do not exceed the recommended dry film thickness
• Should not be applied or cured at temperatures below 4ºC. Temperature should preferably remain at a minimum of 10ºC
• Do not use on surfaces operating above of 60ºC
• Must be protected from weathering prior to being recoated
• Caution - contains phosphoric acid
• Low flash material - ventilate to keep solvent vapour levels below minimum explosive limit and observe low flash regulations

Application Conditions

• 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 paint coating, the surface should be dry, the Relative Humidity should not exceed 85% and the steel temperature should remain at least 3°C 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

Health and Safety

• Containers are provided with safety labels which should be observed
• Further information about hazardous influences and protection are detailed in individual product safety data sheets in the attachments section above.
