Fine-sil300b is a special silica for inkjet printing consumables and photo paper. It is a good inkjet printing medium with large pore volume, good dispersion and suspension, strong ink absorption performance, high color saturation and fast curing speed, so as to improve the printing quality of products and improve the production efficiency of manufacturers.
1、 Product features
- With good extinction effect, it can be used to make semi dumb, soft light, full dumb or even matte coatings.
- Good dispersibility. It can be dispersed below 15 µ m by high-speed stirring.
- The paint film has good transparency and will not form fog shadow.
- It has no effect on the drying, storage and curing of the coating.
- The paint film is flat and smooth, fine and wear-resistant, with good scratch resistance and impact resistance.
- It has no effect on the durability and weather resistance of the paint film.
- Good anti sedimentation, long storage life of the coating, no hard precipitation will be generated.
- The matting powder is evenly arranged and feels good.
2、 Use of products
The matting agents must be fully dispersed in the coating in order to give full play to their role. Fine series products can be easily dispersed in the coating with a standard high-speed disperser. When using, users must pay attention to the factors affecting the dispersion, such as blade diameter, container size, height of coating slurry, linear speed of impeller, etc.
