[Cost Reduction] Rust-free magnetic paint filler - Filler with ferrimagnetic properties - MagniF (Magnetite)

The MagniF series magnetite is an environmentally friendly material as it is a naturally occurring mineral. The ferrimagnetic MagniF blended paint imparts properties that attract magnetic force to the painted area. Additionally, while it is a magnetic filler, it has superior rust resistance compared to iron powder-based fillers. Furthermore, since our products are natural rather than synthetic, it is possible to keep costs down. Please feel free to download for more detailed information.          ↓↓↓↓↓↓↓

Applications/Examples of results

MagniF can be used in many paints due to its excellent dispersibility and high chemical stability. Among them, the most common coating type is water-based paint. MagniF 25 is the most commonly used grade for magnetic paint applications because it has a good balance between magnetic effect and the specific surface area of the powder. The typical filling amount is 40 to 60 wt.%. To enhance magnetism, methods such as increasing the thickness of the coating layer or creating multiple coating layers are employed. Additionally, adding MagniF to the base coat generates a painted surface that attracts and holds magnets, and it has been primarily adopted in magnetic paints such as the following: ■ Wall coatings ■ Blackboard paint ■ Furniture coatings Please feel free to download for more detailed information.
