IOTA FINE–SIL 516 silica
IOTA FINE-SIL516 silica is superfine precipitated silica by specially treated, which has strong adsorption and good dispersibility. It is mainly used in electrochemical aluminum, paint, ink and other industries for adsorption, anti-sinking & thickening. It can replace the high price diatomite which is the raw material to produce primer in the paint & coating industry.
IOTA FINE-SIL 300 Extinction powder
IOTA FINE-SIL 300 Extinction powder is a special kind of silica precipitant made of special silica sol-gel process. Its advantages are good hardness, strong dispersion, and good refractive index. The effect is very good used as the coating extinction in the paint and coating industry.
IOTA FINE-SIL300A Extinction powder
IOTA-300A Extinction powder is special for furniture paint, paint, leather, artificial leather and plastic surface. Its good hardness let the paint film has good wear resistance and scratch resistance. It has strong dispersion & good suspension. There is no hard precipitation by long time leave unused. The refractive index is good.
IOTA FINE-SIL 300B Silica
IOTA FINE-SIL 300B is special silica for Spray painting consumables, Photographic paper. It is a kind of good inkjet printing media, its big hole, good dispersion and suspension, strong ink absorption performance, high color saturation, quick curing speed, could improve the printing quality and efficiency for manufacturers.
Product features
- Good extinction effect. Could be used to make semi-matte, lambency, full - matte and even matt and other matt painting.
- Good dispersion. It could be dispersed to 15μm by high speed stirring.
- The paint film has good transparency of, does not form fog.
- It has no effect on drying storage and curing of paint.
- The film is flat and smooth, fine and wearable, has good abrasion resistance and impact resistance.
- No influence on the durability and weather resistance of the film.
- Good anti sinking, do not produce hard precipitation during the storage period.
- The extinction powders are uniform and feel good.
Products uses
Extinction powder must be fully dispersed in coating, so can play their roles. FINE series products can easily dispersed into the paint by standard high-speed dispersion machine, users must pay attention to blade diameter, container size, the height of the coating slurry, impeller rotational speed and so on are the factors influencing dispersion when doing dispersion.
