Epoxy aluminum tripolyphosphate primer

EAL-26 Epoxy Aluminum Tripolyphosphate Primer

Product Introduction:

This product is a high-performance two-component epoxy resin primer, based on a specially selected epoxy resin and using aluminum tripolyphosphate as the main anti-rust pigment. It not only provides excellent corrosion protection but also exhibits superior adhesion and weather resistance. As a multi-functional primer, it is suitable for a variety of metal substrates and is an indispensable first line of defense in heavy-duty anti-corrosion coating systems. Its formula is free of heavy metals, complies with environmental regulations, and is an ideal alternative to traditional lead- or chromium-containing anti-rust primers.

characteristic:

Excellent corrosion resistance: Aluminum tripolyphosphate effectively inhibits metal corrosion and provides long-lasting rust protection, making it particularly suitable for harsh industrial environments.

Excellent adhesion: It has excellent bonding strength to a variety of substrates such as steel, galvanized parts, and aluminum alloys, and is not easy to fall off or delaminate.

Excellent chemical resistance: The cured paint film can resist the erosion of various chemicals, such as acids, alkalis, salt water, and petroleum products.

Excellent physical properties: The paint film is tough, wear-resistant, and impact-resistant, effectively resisting mechanical damage.

Free of heavy metals: The formula does not contain harmful heavy metals such as lead and chromium, complies with environmental standards such as RoHS, and is harmless to the environment and human health.

Excellent workability: easy to spray, brush or roll, good leveling properties, moderate drying speed, and convenient for subsequent topcoat application.

use:

This product is widely used in various metal structures and equipment requiring long-term corrosion protection. Its main applications include:

Industrial equipment: suitable for pipelines, storage tanks, steel frame structures, etc. in industrial facilities such as chemical plants, power plants, and oil refineries.

Bridges and steel structures: As an anti-corrosion primer for large bridges, stadiums, factories and other steel structures.

Machinery manufacturing: Rust protection for metal parts of engineering machinery, agricultural machinery, ships, etc.

Instructions for use:

Surface treatment requirements:

Use a solvent to remove visible grease, oil, lubricants, cutting fluid, and other soluble contaminants from the metal surface that may affect adhesion, or use other methods to prepare the surface condition for the coating application, following the SSPC-SP1 surface treatment standard to prepare for subsequent protective coating applications.

The steel structure surface must be sandblasted to Sa2.5 ( very thorough sandblasting ) or SSPC-SP10 grade. Without using a magnifying glass, at least 95% of the surface area should be free of any visible oil, grease, dust, dirt, scale, rust, coatings, oxides, corrosion products, and other foreign matter. The surface roughness should be in the range of Rz 30-75μm.

Power tool treatment must meet St 3. This standard defines the use of power tools ( such as power wire brushes, grinders, abrasive discs, etc. ) to remove loose rust, scale, old coatings, and other foreign matter from steel surfaces until the surface has a metallic sheen. However, minor scratches and discoloration are permissible. It is equivalent to SSPC-SP3 in the US SSPC standard .

Surface defect treatment: This includes weld slag, burrs, cracks, holes, etc. These defects affect the adhesion and protective effect of the coating and should be removed or repaired as much as possible.

After surface treatment, a thorough inspection should be conducted to ensure that there are no contaminants or defects such as oil, grease, dust, dirt, scale, rust, welding slag, or burrs before proceeding with the next step.

Under any atmospheric conditions, it is best to perform the painting work within 1 hour after the completion of the "surface treatment" procedure , and no later than 8 hours after the "surface treatment".

Different coatings have different requirements for surface cleanliness and roughness. Please discuss this in detail with our sales staff before using this product.

Construction environment requirements:

Coating application should be carried out under suitable environmental conditions to ensure the quality of the coating. The following factors should be considered:

Temperature: Please construct within the recommended temperature range. Generally, it is not advisable to construct in environments below 5 ℃ or above 40 ℃.

Humidity: The relative humidity should not exceed 85% . Avoid construction in humid or rainy weather.

Wind speed: Excessive wind speed will affect the spraying effect; avoid construction on windy days.

Surface temperature: The surface temperature of the steel should be at least 3 °C ​​higher than the dew point temperature to avoid condensation on the surface.
