Application
It can widely be applied in:
1. Industrial Coating, Metal baking Coating, Decorative Coating, Plastic Coatings.
2. Printing Inks, Gravure Printing Ink, Offset Printing Ink, Screen Printing Ink, Printing Packing Material.
Special application areas include: water-based coatings, waterborne UV coatings, clear coatings, coatings for leather and films, as well as all types of top coats.
Package and storage
1. Package : 5kg / bag
2. Storage : Kept in a low temperature, dry and ventilated place, avoid direct sunlight.
During storage they tend to build up sediment, this is particularly the case with untreated silicas. To avoid this tendency combinations of silicas and wax or pyrogenic silicas are used.
It is possible to adjust the matting degree under angle of 45°, 60° and 85°
The coatings containing silica matting agents are recoat-able. All of them are 'stir-in' products"
3. Shelf life : One year in ventilating, cool and dry area.
