Product Constructio
Applicable Substrate And Surface Treatment:
New steel: Remove grease from the surface with an appropriate detergent and rinse the surface with fresh water for salt and other dirt. Remove the welding slag, smooth the weld and sharp edges, spray clean to Sa2.5 grade (ISO8501-1), the surface roughness reaches Rz40μm~75μm (medium roughness in the ISO8503-1 comparison plate) is the best, it is best to apply the primer within 4 hours after spray cleaning.Galvanized surface maintenance: use appropriate detergent to thoroughly remove the grease on the surface, wash off salt and other dirt with high-pressure fresh water, use power tools to polish small areas of rust, and recoat with this product.
Construction And Curing Environmental Conditions:
The construction environment temperature is 5~50 °C, the relative humidity of the air is not more than 80%, and the surface temperature of the steel should be greater than the dew point of 3 °C; Bad weather such as rain, fog, snow, strong wind and heavy dust is prohibited for outdoor use;In summer, the temperature is high, be careful with dry spraying, and during construction and drying in narrow spaces, a lot of ventilation is required;
Construction Method:
Airless spraying and air spraying are recommended, brush coating and roll coating are only recommended for pre-coating, small area painting or repair.

Product Use
It can be used for long-term anti-corrosion of steel, which can be used in a single layer, or can be coated with a matching heavy anti-corrosion coating on the surface to play a synergistic role to meet a variety of protection requirements. It is the best material to replace or repair hot-sprayed zinc and hot-dip galvanized layers.
