Weather-Resistant Top Coat
Dachin AL 711
Cold spray silver
Main Composition
The coating consists of modified resin, additives, pigments, and organic solvents.
Main Characteristics
The cured film exhibits excellent adhesion, hardness, gloss, and decorative properties, along with superior weather resistance. It effectively prevents moisture and UV damage to the coating. When applied over Dachin DZ-6000 cold galvanized primer, it protects the zinc layer, enhancing corrosion resistance.
Main Applications
Designed for decorative coating on hot-dip galvanized surfaces or repair of such surfaces.

Data based on standard film thickness applied to steel substrate.
Application
- Dachin AL 711 Silver Coating is recommended for application via airless spray for optimal single-coat film formation.
- Surface temperature must remain at least 3℃ above dew point with humidity <85%.
- Ensure ventilation in enclosed spaces during application.
- Thoroughly mix the coating with the hardener as required before use. Use only prepared quantities, stir thoroughly, and maintain tool cleanliness before and after application.
- Avoid contact with water, acids, or alkalis during mixing and application. Ensure the hardener container is sealed after mixing to prevent curing waste.
- Allow full curing for 7 days before putting the coated surface into service.
