Primer
Product Description
It is composed by epoxy resin, zinc chrome, zinc oxide and rust preventive additive. The film can be naturally dried or dried at low temperature. The film is tough and good at adhesion. The anti-damp and fog and salt resistance performance can be enhanced if used with phosphatizing paint.
Design Purpose
It is applicable to surfaces of aluminum metal and other nonferrous metal, especially suitable for rust protection and priming of the facilities in coastal areas and hot and humid areas.

Surface treatment | *Steel with oxide skin: treated with shot-blasting or sand-blasting to reach Swedish de-rusting standard; *Steel without oxide skin: polished with pneumatic or power-driven elastic grinding discs up to Class St 3; *Steel coated with Workshop primer: conduct second rust cleaning with slight sand blasting or pneumatic (power-driven) elastic grinding discs to reach Class St 3 of Swedish de-rusting standard. | |||||||||||||||
Construction condition | Substrate temperature shall be more than dew point above 3℃, relative humidity shall be less than 85%; If the substrate temperature is lower than 5℃, epoxy and curing agent stop reaction, construction can’t be undertaken. | |||||||||||||||
Prior primer | Ethylene phosphating primer, zinc-rich epoxy primer, inorganic zinc silicate primer. | |||||||||||||||
| Finishing paint | Epoxy resin paint, chlorinated rubber coating, acrylic acid coating, alkyd enamel and high chlorinated polyethylene coating. | ||||||||||||||
Packing Specification | Container of 20 liters can load Component of 24kg, container of 5 liters can load Component B of 4kg. | |||||||||||||||
Considerations | Dry spray easily occurs when construction is in high temperature season. In order to prevent the occurrence of dry spray, add diluent to make adjustment until there is no dry spray. | |||||||||||||||
Safety guide | Avoid inhaling solvent vapors and painting mist for long term, skin and eye may not contact with the product. Forced ventilation shall be provided when applying the paint in confined spaces or stagnant air, although in good ventilation, protection tools shall be worn. | |||||||||||||||
