V. Construction Technology

Instructions for Use:

Thoroughly mix both components by stirring or using a power mixer. Ensure complete re-mixing before use. Do not mix freshly mixed material with previously mixed material. Curing speed depends on temperature; ventilation conditions, film thickness, humidity, dilution, and other factors will also affect drying rate. The mixing temperature of the base material and hardener should be above 15°C; otherwise, add diluent to achieve the required viscosity for application. Excessive diluent may reduce anti-sagging properties and slow down curing, decrease film thickness. Add the diluent after mixing. The actual coating rate should be reduced by approximately 5% to 25% (depending on the application method).

2. Construction:

Steel: All rough welds, sharp edges on the surface are ground smooth and slag from welding is removed. The surface is cleaned of grease, oil stains, and other contaminants.

When exposed to atmospheric conditions for construction, the base material's temperature should be between 5℃ and 45℃, and at least 3℃ above the dew point. Relative humidity should be less than 85%. Construction is strictly prohibited during fog, rain, snow, or strong wind conditions.

Brush/roll coating: Suitable for small area applications, apply the mixture to the treated surface. Add epoxy thinner (X-2) 0-5% for convenience if necessary. Multiple coats are required to achieve the desired thickness when brushing or rolling.

Air Spray: Generally does not require thinning, but for convenience, up to 0-5% of epoxy thinner (X-2) can be added.

Airless Spray: Generally does not require thinning, but for convenience, up to 5% of epoxy thinner (X-2) can be added. The pressure ratio is 23:1 or 32:1, with a nozzle size of 0.38-0.43mm.

Coating: Proper methods should be used to inspect the previous coating for peeling, such as the cross-hatching or grid method. If peeling is detected, the aged coating must be removed, ensuring the surface is free of grease, oil stains, and other contaminants. The coating can also be applied in a manner of coating - glass fiber fabric - coating.

Primer Coating System: Epoxy Zinc-rich Primer; Epoxy Anti-rust Primer

Tool Cleaning: Uses epoxy thinner X-2

3. The temperature of the paint itself should be above 15°C for normal application performance. The ideal application environment temperature should not exceed 35°C and application with heat is prohibited. Roller coating is generally recommended, with 2-3 coats of primer and 2-3 coats of topcoat. During application in confined spaces and during drying, ample ventilation is required to avoid rain, with a 24-hour interval between coats. The entire coating system should be maintained for 7 days before use.

4. Film thickness can be adjusted as required; however, this will accordingly alter the amount used and affect drying time. If the coating surface is contaminated during application, it is advisable to thoroughly clean with high-pressure freshwater before recoating, allowing it to dry naturally.

5. This product is highly effective in rust prevention when re-coating on phosphatized substrates.

6. Various alkyd magnetic paints, tinted paints, polyurethane magnetic paints, acrylic magnetic paints, chlorinated rubber coatings, chlorinated polyvinyl chloride coatings, nitro magnetic paints, and epoxy coal tar coatings are all suitable for matching with this product.

7. This product is not suitable for protection against high concentration acid or alkali corrosion.

8. The thinner (X-117) should be added after the paint base and hardener are mixed. Excessive thinning agent will result in reduced anti-sagging properties and film thickness.

9. Store in a cool, dry place, sealed, for at least 12 months.
