Frequently Asked Questions (FAQ)
Q
What does "solvent-free" mean for this epoxy hardener, and why is it important?
"Solvent-free" means the product contains no volatile organic solvents, resulting in a very high solid content (98% ± 2%). This is important because it reduces VOC emissions, improves environmental safety, and allows for the formulation of high-build coatings with excellent film performance.
Q
What substrates is this hardener compatible with?
This hardener exhibits excellent adhesion to a wide range of substrates, including concrete, ABS, PC, PVC and other plastics, as well as various metals such as steel and aluminum.
Q
What is the gel time and why does it matter?
The gel time is approximately 15 minutes at 25℃ and 55% relative humidity. This indicates the working window before the mixed coating begins to cure. It is important for planning application time and ensuring proper mixing and spreading before gelation occurs.
Q
What are the main application areas for coatings made with this hardener?
This hardener is well-suited for anti-corrosion coatings, industrial flooring coatings, and waterproof coatings. Its excellent chemical and weather resistance makes it ideal for demanding environments such as industrial plants, marine structures, and infrastructure.
Q
How should this product be stored to maintain its quality?
The product should be stored in a dry, cool, and well-ventilated area, away from direct sunlight, rain, and ignition sources. The shelf life is 12 months from the production date under original sealed packaging. Once opened, it should be used promptly or resealed tightly to prevent contamination and moisture ingress.
Q
What packaging size is available, and is it suitable for large-scale industrial use?
The product is available in 200 kg drums, which is a standard industrial packaging size. This makes it well-suited for large-scale coating projects, industrial manufacturing, and bulk procurement by coating formulators and contractors.
