Coating grade Nano tio2 KNR-508

The  appearance  of KNR-508  was  the white  fluffy powder,  which was  coated with  hydrated  alumina  or/and  hydrated zirconia,  and the  main chemical constituents are titanium dioxide. The paint film not olny had good light resistance, but also had angle-dependent optical effect, which made from KNR-508 and aluminum paint and other materials.

Performance

Remarks: The test conditions for ultraviolet absorption of product  are as follows: Wavelength range from 200nm to 400nm,disperse medium was water, addition of product was 0.01%(wt).

Scope of application

KNR-508  was  suitable  for  outdoor  high-grade  painting,   such   as  automotive

metallic, facade coating, wood paint, aircraft skin paint and so on.

Application method

1. The mixture was fully dispersed to obtain the color paste which color was gemstone  white  (frost  blue),  which  was  made  of  resin,  dispersant,  solvent  and nano-titanium dioxide.

2. Then the color paste was added to the mixture according to the formulation  and  processing  method of  the  target  product.  The  optimal  dipersion method  was  as  follows: the slurry concentration of KNR-508 was 10%  (wt.) to 20%(wt.), the  slurry  was lapped 8 times by sand mill, the grinding medium was zirconia beads which diameter was 1.0 to 2.0mm, the filling rate of zirconia beads in grinding was about 80%.

3. The quality percentage of KNR-508 in metallic paint products was 3%~10%.

Package and storage

Standard package 10kg/box, 5 kg/bag, and keep in dry and cool inside room avoid of sunshine directly.
