Application Scope
This high-performance fluorocarbon topcoat is specifically formulated as the finishing layer in epoxy coating systems, providing exceptional corrosion protection and decorative performance for demanding environments including offshore structures, chemical/petrochemical plants, bridges, and other steel structures requiring both superior weather resistance and long-term color retention, making it ideal for industrial applications where both durability and aesthetic appeal are critical.
Application Guidelines for Fluorocarbon Coatings:
This fluorocarbon coated must be applied at ambient temperatures above 10°C, with the paint temperature maintained above 15°C and relative humidity below 80%. Ensure surfaces are dry, clean, and 3°C above dew point to prevent condensation. Adequate ventilation is required in confined spaces during application and curing. Avoid application during rain, snow, or fog.
Mix components precisely as per label instructions and use within the pot life, which shortens at higher temperatures. Before recoating, remove oil, moisture, weld spatter, and dust. Drying time varies with temperature, humidity, and film thickness. If exceeding the maximum recoat interval, roughen the surface to ensure intercoat adhesion.
Store in a cool, dry, ventilated area, away from heat sources and direct sunlight. Workers must wear proper PPE, and fire prevention measures must be in place. Open flames and smoking are strictly prohibited.
Packaging
Size: 25kg per set
Shelf Life:
When stored in a cool, dry, and shaded area, the unopened product has a shelf life of one year (at 25°C).
Fluorocarbon Coating in Steel Structure Applications: Matching Systems
In practical applications on steel structures, fluorocarbon coatings are typically used in combination with primers, intermediate coats, and topcoats to achieve optimal anti-corrosion protection.
I. Selection of Matching Coatings for Fluorocarbon Coatings
01 Primer Selection
Primers paired with fluorocarbon coatings should exhibit strong adhesion, excellent rust resistance, and good workability. Common choices include epoxy primers, epoxy zinc-rich primers, or inorganic zinc-rich primers. These are widely used in anti-corrosion coatings for steel structures in bridges and buildings.
02 Intermediate Coat Selection
Intermediate coats for fluorocarbon coatings often include epoxy mica iron intermediate coatings or epoxy high-build intermediate coatings. These enhance the overall anti-corrosion performance, improve barrier properties, and ensure effective bonding between the primer and topcoat while blocking corrosive agents.
II. Common Matching Systems for Fluorocarbon Coatings
System 1: Epoxy zinc-rich primer + epoxy mica iron intermediate coat + fluorocarbon topcoat
System 2: Inorganic zinc-rich primer + epoxy sealer + epoxy mica iron intermediate coat + fluorocarbon topcoat
System 3: Epoxy primer + epoxy high-build intermediate coat + fluorocarbon topcoat
In actual steel structure coating projects, the selection of a suitable system should consider factors such as construction requirements, environmental conditions, project specifications, corrosion risks, and cost-effectiveness.
