Product Description Product DescriptionProduct Name: Steel Structure Anti-Corrosion Epoxy Zinc Rich Primer Paint1.Introduction:Epoxy zinc-rich primer is a two-component coating with epoxyresin as the base material, phosphor iron powder, rust-proof pigment, etc., and cured by polyamide. It is packed by dual components A and B. Characteristics: High shielding property, superior anti-rust property, strong adhesion, and good oil and water resistance.

Avoid rainy, foggy, windy and sandy days and condensation in the morning and evening for outdoor construction.4.Notes:1. Before use, use mechanical stirring to mix component A evenly, and then mix it evenly with component B.2. Regularly stir during the coating process to prevent sedimentation, which can cause an imbalance in the powder to liquid ratio and affect the quality of the paint film.3. It is recommended that the dry film thickness be ≥70μm, and 1 to 2 coats be completed.4. After mixing, the two-component paint is generally used up within 5 hours. Exceeding the time may affect the coating quality.5. After the curing agent is used up, it must be covered tightly and used up as soon as possible to prevent losses caused by reactions with water vapor in the air. Company ProfileThe SINGAL brand originated in 2000 and has a history of more than 20 years.Since its establishment,SINGAL has been committed to the innovative development of water-based coatings and special coatings.The Company has planned to build a new material industrial park covering an area of 300 mu and invested in an industry-integrated production unit with an annual output of 500,000 tons of water-based special coatings.Now,it has a post-doctoral workstation and a provincial technical center,has become the executive director unit of China National Coatings Industry Association and the chairman unit of Shandong Coatings Industry Association,and has won many industry honors such as China Famous Trademark,National Inspection-free Product,Shandong Famous Trademark,Shandong Famous Brand Product, Reliable Enterprise of Building Fire Protection,and Selected Brand of Industrial Coating,etc.It has been recognized as High-tech Enterprise and Technologically Advanced Enterprise,and has relevant construction qualifications.

Below are the detailed steps: 1. Pre-Construction PreparationMaterial Preparation:Confirm the coating model and performance meet design requirements.Check the shelf life and properly mix primers, intermediate coats, topcoats, and hardeners as per ratios.Tool Preparation:Prepare spraying equipment (e.g., air compressor, spray gun), brushing tools, sandpaper, grinders, masks, and gloves.Substrate Inspection:Ensure the base (metal/concrete) is flat, free of cracks, oil, or rust; repair if necessary.Environmental Requirements:Temperature: 5°C-35°C; humidity ≤85%.Avoid rain, strong wind, or dusty conditions. 2. Surface TreatmentMetal Surface TreatmentRust Removal:Use sandblasting, shot blasting, or manual grinding to remove rust/oxidation, achieving Sa2.5 (uniform roughness) or St3 (no visible rust).Degreasing:Wipe with solvents to remove oil and dust.Concrete Surface TreatmentGrinding:Remove loose particles and smooth the surface; fill cracks with putty.Drying:Ensure moisture content ≤8% to prevent blistering. 3. Coating ApplicationPrimer Application:Apply evenly via brushing/spraying (50-80μm thickness).Allow drying per manufacturer's instructions (typically >24 hours).Intermediate Coat:Apply after primer curing (e.g., fiberglass-reinforced coat) for thickness/impermeability.Sand smooth post-drying.Topcoat Application:Apply 2-3 layers for weather/chemical resistance.Total thickness: 200-300μm (industrial use); inspect for bubbles/voids between layers. 4. Quality Inspection & AcceptanceVisual Check:Coating must be smooth, free of sagging, cracks, or pinholes; color uniformity required.Thickness Test:Use a thickness gauge (3+ random checks per ten squre meter; ≥90% compliance).Adhesion Test:Cross-cut test: No peeling = pass.Spark Test:Use a holiday detector to locate coating defects; repair if leaks found.
