Introduction
Epoxy zinc rich antirust primer is a zinc containing antirust primer mainly used by Budweiser paint industry
The paint is developed for steel structure substrates that cannot be derusted by sand blasting and need zinc rich primer
It has excellent adhesion and rust resistance

Package specification: 25kg paint + 2
5kg curing agent
Color: gray
Gloss: matte
Price: it is comprehensively determined according to the one-time quantity, shipping address, etc
Diluent: epoxy diluent, 2 sets of paint matching 1 set of diluent
3
Applicable working conditions
Substrate: bare steel (i
e
steel and iron surfaces without painting and phosphating treatment)
Surface treatment: sand blasting, dynamic derusting, manual derusting to more than 90% of the surface without oxide skin
Environment: anticorrosive environment, alkaline corrosion, salt spray corrosion, outdoor environment, etc
It needs to be used with the top coat

5
Construction technology
Construction conditions
The substrate temperature shall not be lower than 5 ℃ and at least 3 ℃ higher than the air dew point temperature (temperature and relative humidity shall be measured near the substrate)
Good ventilation is usually required to ensure normal drying of paint
Construction method
Spraying: airless spraying or airy spraying
High pressure airless spraying is recommended
Pay attention to adjusting the viscosity and air pressure of the coating when using air spraying
The diluent should not exceed 10%, otherwise the coating performance will be affected
Brush coating: it is recommended to use it in pre coating and small area coating, but it must reach the specified dry film thickness
Construction parameters
Mixing ratio (weight) 10:1
Service life after mixing (23 ℃) 6 hours (decreases with the increase of temperature)
Diluent / cleaning agent H series special diluent
Guiding data for airless spraying
Nozzle pressure 150~200 kgf / cm2
Nozzle aperture 0
4~0
5 mm
Spraying range 40~80 degrees
Dilution 0~10% (based on paint weight)
Anti corrosion and antirust effect of epoxy zinc rich antirust primer:
The anti-corrosion and anti rust effects of zinc rich paint are mainly reflected in cathodic protection and self-healing
1
Cathodic protection
Cathodic protection is achieved by sacrificing anode
Zinc rich primer contains ultra-fine high activity zinc powder as antirust pigment, which is different from other inert anti-corrosion coatings that only provide fatigue
Zinc powder will react with moisture in the air before steel when encountering moisture
2
Repair effect
In the area where the paint film is damaged, the zinc powder in the zinc rich primer reacts electrochemically with moisture to produce zinc oxide, which is deposited on the surface of the damaged steel structure to form an inert protective coating
This kind of "self repairing" effect is especially remarkable with the new paint film
Zinc rich primer is widely used as a long-term anti rust primer for steel structures in strong corrosive environment because of its anti-corrosion and anti rust effects in the above two aspects, which has excellent salt spray resistance and damp heat resistance
