major component 
The epoxy zinc rich workshop primer is prepared with epoxy resin as the base material, ultrafine metal zinc powder, additives, solvents, and polyamide resin as the curing agent. Two component packaging consisting of A and B.
Main characteristics
It has cathodic protection effect, excellent rust prevention performance, and excellent adhesion; Outstanding heat resistance, when welding and cutting, the burning area is very small, which does not affect the welding performance; And it has characteristics such as oil and water resistance.
Main purpose
Widely used in metallurgy, containers, various types of transportation vehicles, engineering machinery, steel plate pretreatment shot blasting, especially suitable for rust prevention of steel structures, it is an ideal metal pretreatment shot blasting and rust prevention maintenance primer.
Technical indicators
Appearance of paint film: The paint film is flat and smooth, and the color meets the standard sample
Drying time: Standard thickness single coating, 25 ℃,
Surface dry ≤ 2h, actual dry ≤ 12h
Adhesion: ≤ 2 (circle marking method, grade)
Welding burn width: ≤ 15mm
Salt water resistance (3%, 168 hours): no foaming, no peeling, no rusting
Basic parameters
Construction time limit: 8 hours, (25 ℃)
Flash point: 24 ℃ (paint), 27 ℃ (curing agent)
Suggested number of coating passes
Prepare a pre coated primer and apply one coat, 25 ± 5 μ M
Apply anti rust primer with a dry film thickness of 55 ± 5 μ M
surface treatment
The paint base should be clean, free of oil stains, dust and other pollutants, and sandblasted or shot blasted to achieve Swedish Sa2.5 level, while manual mechanical rust removal should reach St2-3 level.
Painting method
Airless spraying: air spraying roller coating/brush coating
Storage period: Store in a cool, dry, and ventilated place, with paint for one year and curing agent for six months.
matters needing attention
1. Read the instructions before construction;
2. Before use, mix the paint and curing agent according to the required ratio, mix as much as needed, mix evenly before use, and use up within 8 hours;
3. During the construction process, keep it dry and clean, and the packaging barrel of the curing agent must be tightly covered after paint preparation to avoid gelation;
4. During construction and drying, the relative humidity should not exceed 85%. This product can only be delivered for use after 1 day of coating;
5. The surface of the epoxy zinc rich workshop primer is prone to the formation of zinc salts, and should not be exposed for a long time before the coating is applied. If painting at longer intervals, it is recommended to use H53-89 cloud iron epoxy intermediate paint for sealing.
Safety measures: refer to the product safety technical manual (MSDS).
