Intermediate Coat FAQ
Q: What is the primary purpose of an Intermediate Coat?
A: The Intermediate Coat serves multiple critical functions in a coating system. It provides enhanced corrosion protection by creating a barrier against moisture and chemicals. Additionally, it improves the adhesion between the primer and topcoat, ensuring long-term durability. The Intermediate Coat also helps to build film thickness for better protection and can provide specific properties like chemical resistance or flexibility that might not be present in the primer or topcoat.
Q: Can Intermediate Coat be used as a standalone protective coating?
A: While Intermediate Coat offers substantial protective properties, it's not designed to function as a standalone coating system. Its formulation is optimized to work within a complete coating system (primer + intermediate + topcoat). Using it alone would compromise long-term performance and durability. The topcoat provides necessary UV protection and aesthetic finish, while the primer ensures proper adhesion to the substrate.
Q: How does temperature affect the application of Intermediate Coat?
A: Temperature significantly impacts the application and performance of Intermediate Coat. Below 5°C, the coating may not cure properly, leading to poor film formation. Above 40°C, the coating may dry too quickly, affecting leveling and potentially causing application defects. Ideal application conditions are between 15°C and 30°C with relative humidity below 85%. In extreme temperatures, adjust thinner ratios as per manufacturer recommendations and consider applying during cooler parts of the day.
Surface Preparation Requirements
Proper surface preparation is essential for optimal Intermediate Coat performance:
- Remove all oil, grease, and contaminants (SSPC-SP1)
- Surface should be dry and free of moisture
- Profile depth: 50-75 microns for new steel
- Remove all loose particles (brush blast if necessary)
- Surface temperature should be at least 3°C above dew point
Compatibility Information
Our Intermediate Coat is compatible with most common coating systems:
| Substrate/Coating Type | Compatibility |
|---|---|
| Epoxy Primers | Excellent |
| Polyurethane Topcoats | Excellent |
| Zinc-rich Primers | Good (check specific product) |
| Alkyd Paints | Limited (consult technical data) |
| Acrylic Topcoats | Good |
Safety and Handling
When working with Intermediate Coat, observe these safety precautions:
- Use in well-ventilated areas
- Wear appropriate PPE (gloves, goggles, respirator)
- Avoid contact with skin and eyes
- Do not ingest
- Keep away from heat sources and open flames
- Store in cool, dry place
