Instructions of Epoxy Zinc-Rich Primer
It is two components epoxy zinc-rich primer heavy corrosion by a zinc primer, epoxy resin and other components. On steel surface treated to form a hard, wear-resistant, durable film, and provide long-lasting cathode protection.
Property of Zinc Rich Epoxy Primer Paint
A. High zinc content, in line with international standards ISO12944 and national standards HG / T 3668-2009 related zinc-rich primer composition requirements.
B. The treated steel with excellent adhesion and corrosion performance.
C. Good abrasion resistance, impact resistance.
D. As a shop primer does not affect the performance of cutting and welding.
E. It can be designed to support a variety of paint as a primer, especially heavy industrial and marine environment protection system.
F. Quick drying, can recoat after a short time.
Application of The Zinc Rich Epoxy Primer
Widely applicable to long-term anti-rust primer for steel primer, primer and maintenance, ships, bridges and other steel structures. Especially suitable for industrial, chemical, steel and other heavy-duty offshore matching primer coating.
Surface Preparation of The Epoxy Zinc-Rich Prime
The surface roughness of steel welds, rounded edges and clear the splash-melt welding, cleared the surface of the grease, oil and other pollutants; surface sandblasted to ISO standard Sa2.5 level or power tools rust St3 level; surface roughness of 50-85um, before spraying to ensure the surface is dry and clean.
The weather is good, the substrate temperature of not less than 5 ℃, relative humidity <85%. It must have good ventilation conditions in confined areas to ensure proper drying of the film. Before fully cured coating should not be exposed to oil, chemicals or mechanical stress.</span>
Coating Application of Zinc Rich Epoxy Paint
Mixing mass ratio: Base material (A): The curing agent (B) = 10: 1.
Theoretical amount: 220 g / m2.
Painting passes: spraying or brushing 2 to 3, 60 to 80 microns dry.
Mixing: Use a power mixer component A (base) Stir, then stirring state by mixing ratio of the added amount of group B (curing agent), and fully mixed, while stirring continued momentum needed painting.
Thinner or Cleaner: For supporting diluent.
Curing time: After mixed directly.
After mixing pot life: 5 hours (23 ℃).
The Construction Method of Epoxy Zinc-Rich Prime
Brush: Recommended for small areas, acute sites and pre-coated and refinishing, but must meet the specified dry film thickness.
Spraying: airless spray or air spray, the airless spray is recommended priority.
Air spray: a discharge pressure 0.4-0.7Mpa, nozzle diameter 1.8-2.2mm;
Airless Spray: discharge pressure 15Mpa, nozzle diameter 0.43-0.48mm;
* When used in spray paint, because the need to adjust the viscosity, can be added to a thinner 0-10%.
Precautions
A. The construction and curing required to maintain adequate ventilation.
B. Premature exposure to rain or condensation in the state, its color and luster affected.
C. Heat resistance: resistance up to 200 ℃ dry heat.
D. Weather resistance: can occur when there is no separate outer protective coating exposed some of chalking and yellowing;
E. Chemical resistance: resistant to most s, aromatic hydrocarbon solvents and solvent spills and overflows; not directly used in the acidic environment of use; if no suitable overcoat Do not use strong alkaline environment; when a suitable overcoat when neutral salts, basic salt resistance is excellent.
F. Wear resistance: completely cured after a good wear resistance.
G. Compatibility: polyurethane-based coating can be used with good support.
Shelf Life of The Epoxy Zinc-Rich Prime
Twelve months from the date of manufacture in the original unopened container at 32°C. Subject to re-inspection thereafter. Store in dry, shaded conditions away from sources of heat or ignition.
Package: 20 kg/ barrel.
