Silfit Z 91 in powder coatings

Hybrid, Polyester, TGIC

Calcined product based on Sillitin Z 86.

Silfit Z 91 is applicable in hybrid, polyester and TGIC powder coatings.
The product will be used as a partial replacement of titanium diuoxide. It offers improved scratch resistance, very good flow performance, outstanding impact with higher dosing as well as retention of good weather resistance. Silfit Z 91 offers also better corrosion resistance in the TGIC system.

excellent dispersion properties

low abrasivity

good edge covering

scratch resistance

abrasion resistance

flexibility (Erichsen cupping, impact)

good corrosion protection, especially low delamination and rust creep

good chemical resistance, especially against hot water

improved hiding power or partial replacement of titanium dioxide
