Pyrogenic silica KC2300 is composed of silica, which lubricates and isolates the powder coating particles, making it difficult to adhere and agglomerate between the powder coating particles, improving the fluffiness of the powder coating, improving the dry powder flowability of the powder coating (reducing the rest angle) and the fluidization performance in the powder supply tank. At the same time, due to its characteristics such as large specific surface area, small particle size and porosity, it has a strong moisture adsorption capacity, which can effectively prevent powder agglomeration and improve storage stability. Suitable for all types of powder coatings.
The gas adsorption capacity can effectively prevent powder agglomeration and improve storage stability. Suitable for all types of powder coatings.
1. Technical parameters
- Appearance: white fluffy powder
- Bulk density: 30-60g/L
- pH: 3.7-4.5
- Assay: ≥99.8%
2. Product features
-With the addition of participating in extrusion, it can be used to improve corner coverage, reduce powder flow and enhance coating hardness.
-The addition of dry mixing in powder coating can improve powder looseness, prevent agglomeration, improve storage stability, speed up powder production, and solve problems such as gun plugging and powder accumulation during spraying.
The amount of in-addition involves extrusion, and the dosage is determined according to the test. Or add a dry mix in powder coatings, and the best effect is added when the finished product is sieved, and the dosage is within 0.2% of the total amount.
4. Packaging storage
Multi-layer composite bags, net weight 10kg per bag. The packaging is sealed, stored in a cool and dry place, and the shelf life of reasonable storage is at least 2 years.
