| 6 | QYT-312 Water-based White Corundum Coating |
QYT-312 is a white, water-based coating with a high content of white corundum. This coating can replace the high-density Ganteng powder coating while still delivering smooth, polished casting surfaces. | Suitable for molds (cores) used in all cast steel parts and various alloy castings, it can also be applied to the production of thick-walled cast iron components. | Density: 2.05–2.30 g/cm³ ≥98% after 24 hours of suspension Solid content: 70% Packaging: Plastic drums, 50 kg per drum Shelf life: 3 months |
| 7 | QYT-121 Alcohol-based brown corundum coating |
QYT-121 is an alcohol-based, high-content brown corundum coating. It features excellent thixotropy and suspending properties, low gas evolution, and high strength once the coating has hardened. Additionally, this coating is easy to apply and provides excellent resistance against sand sticking. | The QYT-121 is suitable for sand molds (cores) used in a variety of glass-fiber reinforced and small alloy steel castings, as well as thick-walled iron castings—particularly when paired with resin sand or water glass sand molds (cores).

Application Methods for the Foundry Coating Product Series
Alcohol-based coating
The product is primarily designed for brush application; when diluted with alcohol, it can also be used for immersion or spraying processes. The required viscosity, however, should first be determined through testing. As a general guideline, aim for a viscosity of 12–15 seconds (using a 4 mm nozzle and DIN viscosity cup).
Coating can be dried either by burning or baking. If burning is chosen, ignite the coating immediately after brushing and allow it to dry slowly. If the coating remains unignited or burns unevenly due to excessive drying time post-brushing, lightly sprinkle a small amount of alcohol onto the surface before attempting to light it again.
When applying the coating to large, flat sand molds (or cores), consider using a localized brushing-and-drying approach—apply the coating in specific areas, then ignite those same areas individually for efficient drying. Before use, ensure thorough mixing to achieve a uniform coating consistency.
The product is classified as flammable. Therefore, safety precautions must be observed during storage and use—ensure the environment remains well-ventilated and dry. When igniting or handling the coating for combustion, always follow safety protocols. It’s best to avoid inhaling the solution; if the solution comes into contact with your eyes, rinse thoroughly with plenty of water.
Water-based paint
Before using the product, stir thoroughly. If it’s too thick, you can add a small amount of water to thin it out. The product is suitable for brushing, spraying, and flow-coating applications. To dry the coating, use an oven-drying method with temperatures ranging from 150°C to 500°C. If air-drying with a blowtorch or gas flame, avoid directing the flame directly onto localized areas of the coating to prevent overheating.
It's best to avoid inhaling the paint, and the paint should be stored in a cool, indoor location to prevent freezing.
