Feature
Powder state Matt Hardener material SiO2 is a type of coating additive that is used to improve the hardness and durability
of coatings. It is made from silica dioxide (SiO2) particles that are finely ground into a powder form. When mixed with a
coating material, the SiO2 hardener helps to create a matte finish that is resistant to scratches, abrasion, and other forms
of wear and tear.
This type of hardener is commonly used in automotive coatings, industrial coatings, and other applications where a durable
and long-lasting finish is desired. It can be easily mixed into the coating material and applied using standard painting techniques.
The SiO2 hardener helps to create a smooth and even surface that is resistant to damage, making it ideal for high-traffic areas
or areas that are exposed to harsh environmental conditions.
Overall, powder state matt hardener material SiO2 is a versatile and effective additive that can enhance the performance and
longevity of coatings. Its ability to create a matte finish and improve hardness makes it a popular choice for a wide range of
applications.
Appearance: White powder
Melting point: 210-230 °C
Non-volatile: Min. 98.5%
Application
- HF68 may be applied both in pure epoxy and hybrid (epoxy-polyester) resin powder coatings
-The gloss from 5% to 10% of pure epoxy powder coatings and the gloss from 10% to 70% of Hybrid Powder Coatings can
be easily obtained by using HF68.
-Used in hybrid powder coating, matt or semi-matt gloss can be achieved by replacing some of the polyester in the formulation
with an equivalent quantity of HF68.
