                Zinc yellow epoxy primer

                Performance: Yellow zinc primer is specialized in response to galvanized steel, stainless steel, cold plate, aluminum or passivating workpieces. This primer can be directly sprayed on the substrate without sandblasting or polishing. The product has excellent adhesion, good weatherability and excellent flexibility.
                Application: The Zinc yellow epoxy primer is one of the most widely used industrial anti-corrosion products, which is suitable for the steel rust protection under atmospheric environment and is widely applied in general corrosion prevention, chemical environment, ocean environment and other anticorrosion and weather resistant coatings.

                Supporting system

                The epoxy zinc rich primer can be applied to various industrial environments:
                ?Stainless steel: Zinc yellow epoxy primer + Epoxy micaceous iron oxide intermediate paint + Acrylic polyurethane finish paint
                ?Port, steel construction: Zinc yellow epoxy primer + Epoxy micaceous iron oxide intermediate paint + Aliphatic series isocyanate paint;
                ?Petrochemical storage tank, pipeline corrosion protection: Zinc yellow epoxy primer + Epoxy micaceous iron oxide intermediate paint + Epoxy finish paint/Epoxy asphalt paint

                Construction method
                1、Base material processing
                The coated base material surface must carry out thorough removal of grease, scale, rust, old coating, and etc., using shot or sand blasting method, to reach Sweden derusting standard Sa2.5 grade and roughness of 30-70μm, manual derusting methods can also be adopted to reach Sweden derusting standard St3 grade and roughness of 30-70μm.
                2、Mixture
                According to the weight ratio (the label on the product packaging shall prevail)
                When mixing, under the condition of stirring the main agent continuously, slowly pour in curing agent to make it fully ad evenly stirred.
                20 min after curing of the well mixed coating, filter with 60-80mesh screen, and pour into another container for spare use.
                The mixed coating is valid for 3 hours; please arrange the use according to the construction progress.
                3、Construction conditions
                Coating operation shall be performed as soon as possible after the substrate processing, generally not exceeding 8 hours. The substrate surface temperature and environmental temperature are generally no less than 10℃, the surface temperature shall be at least 3℃ higher than the dew point temperature, and the relative humidity of the air shall not exceed 85%.
                4、Coating method
                This coating can use brush coating, airless spraying and auxiliary air spraying method for construction.
                5、Dilution
                Generally the coating shall use the matching thinner to adjust viscosity and cleaning tools.
                6、Coating intervals
                One-component paint can carry out later coating after drying; two-component paint is suggested to have the coating time intervals as follows:

                Substrate temperature 5℃ 20℃ 30℃
                Shortest 48h 24h 20h
                Longest 12 months
