AT3600 original German imported silica coating matte powder

Short Description:

Extinction powder AT3600 is a kind of silica extinction powder produced by gas phase process with polydimethylsilane treatment.

Fumed silica is different from wet silica, and the big difference between the two is the amount of adsorbed water and chemically bound water.

The drying loss (105 ° C for 2 hours) and burning loss (1000 ° C for 2 hours) of fumed silica were lower.

As in PU systems and varnishes, these differences are related to performance.

3600 is an extinction powder with remarkable extinction effect and high transparency. Matting powder AT3600 is easy to disperse in coatings, paints and inks. Compared with untreated fumed silica matting powder, the coating with 3600 matting has high abrasion resistance and scratch resistance, and feels extremely strong. This product is specially designed for low gloss radiation-cured coatings.
Chemical composition: fumed silica treated by PDMSD
product characteristics: significant extinction powder effect, easy dispersion, high transparency, abrasion resistance and scratch resistance,
recommended application: coatings, paints, inks and other coatings requiring high transparency and extinction effect
Packaging specifications: 12.5kg/ paper bag,
usage and dosage: silica extinction powder is easy to disperse, can be added in any stage of the production process, alone or with pigments and other additives dispersed. Disperse with a high-speed disperser, first add an appropriate amount of extinction powder to the coating, start slow stirring, and then rise to the appropriate speed (line speed in 10~20m/s, according to the viscosity of the system), stirring for 10~20 minutes, to obtain a uniform dispersed phase without coarse particles. Can not grind, otherwise affect its extinction efficiency.
