*Product Description:

*Product Feature:

. Weather Resistance: It offers a certain degree of water and UV resistance, maintaining its performance in a variety of climates and is suitable for indoor and outdoor metal protection.
. The paint film is tough and has strong adhesion, and can firmly adhere to metal surfaces such as steel.
. Strong Adhesion: It bonds strongly to substrates such as steel and cast iron, and the coating resists peeling.
. Flexibility and Impact Resistance: The water-based alkyd anti rust paint film is flexible and can withstand moderate impact without damage, making it suitable for a variety of substrates.

*Technical Datas:

*Product Application:

Water-based alkyd anti-rust paint is widely used to prevent rust on indoor and outdoor steel structures. This includes steel beams in factories, bridges, and stadiums, as well as industrial equipment such as mining machinery, agricultural machinery, pipelines, and the exteriors of storage tanks. It also applies to municipal infrastructure such as guardrails, light poles, ventilation ducts, and trash cans. It also applies to vehicle components such as truck chassis, carriages, and construction vehicle parts.

*Surface Treatment:

To ensure film adhesion and long-term corrosion protection, the substrate surface must be thoroughly cleaned of oil, rust, scale, old paint, and loose impurities before application. Preparation standards should meet the following:
All surfaces to be coated should be clean, dry and free from contamination. Before painting, all surfaces should be in accordance with the ISO8504: 2000 standard evaluation and processing.
The scaled steel is blasted to Sa2.5 grade, surface roughness is 30-75μm, or pickled, neutralized and passivated;
Oxide-free steel blasted to Sa2.5 grade, or polished to St3 grade with pneumatic or electric elastic grinding wheel;
Steels coated with workshop primer paint film damage, rust and white rust on zinc powder primer should be derusted twice, white rust is removed and polished to St3.
Other surfaces This product is used for other substrates, please consult our technical department.

*Construction Condition:

The substrate temperature is not lower than 5 ℃, and at least 3℃ higher than the air dew point temperature and the relative humidity is <85% (temperature and relative humidity should be measured near the substrate).Construction is strictly prohibited in fog, snow and windy weather

*Construction Steps:

Step 1: Substrate Surface Preparation (The Key Step)
The quality of surface preparation directly determines the adhesion and lifespan of the paint film.
Metal surfaces must be degreased and rust-free (to Sa2.5 or St3 standards) to ensure metal surfaces to be painted must be thoroughly clean, completely dry, and free of contaminants such as oil, grease, dust, salt, scale, and loose old paint.Visible moisture or condensation is not allowed.
The treated surface should meet the design cleanliness and roughness standards, and paint should be applied as soon as possible to prevent rust recurrence or secondary contamination.
Step2: Apply Water-based Alkyd Anti rust Paint
After open the bucket, stir evenly by electric mixer especially any pigments and fillers that have settled at the bottom.Then brush/roll or spray, air spraying is the preferred method for obtaining the smoothest and flattest paint film. If you have professional equipment and techniques, it will be best.The theoretical paint consumption is 0.2kg/m²/coat.(Actual usage may vary depending on surface texture, porosity, application method and operator technique.)
Note:
*If need thinning, dilute with deionized water according to the application viscosity and method (brushing, rolling, or spraying). Adjust the viscosity to suit the specific application method.
* Dilution ratio of 5-20% by weight. Over-thinning will adversely affect film build, hiding power, and long-term durability.
* Before applying the next coat, ensure the previous coat is fully cured, clean, dry, and free of all contaminants.
* Avoid vigorous stirring to prevent the introduction of excessive bubbles.

*Precautions:

▶ Environmental Requirements: Application temperature: 5°C-35°C (Specific adjustments are made according to product characteristics), relative humidity ≤85%.
▶ Compatibility testing is required when mixing with solvent-based paints to prevent brittle coating(a small area test is recommended).
▶ Protective equipment must be worn during sandblasting
▶ Protect from freezing during storage.
▶ Fog, rain, snow, wind and rain is strictly prohibited construction.
