Feature
Silicon dioxide powder, also known as silica, can indeed be used as a hardener for clear paint. Silica is a
commonly used additive in various coatings and paints due to its unique properties.
When added to clear paint formulations, silica acts as a reinforcing agent, increasing the hardness and durability
of the paint film. It can improve scratch resistance, abrasion resistance, and overall mechanical strength.
Additionally, silica can enhance the clarity and gloss of the paint, providing a smooth and shiny finish.
Silica Powder can be incorporated into the paint formulation during the manufacturing process. The amount of silica
used will depend on the desired level of hardness and other performance requirements. It is important to follow the
manufacturer's instructions and guidelines to ensure proper incorporation and dispersion of the silica powder.
It is worth noting that while silica can enhance the performance of clear paint, it may also affect other properties such
as flexibility and impact resistance. Therefore, it is essential to carefully consider the specific requirements of the paint
application and conduct thorough testing to ensure the desired balance of properties is achieved.
Overall, silicon dioxide powder can be an effective hardener for clear paint, providing improved hardness, durability, and
aesthetic qualities.
Advantages
1) Can reduce the gloss of PES/TGIC powder coating to 30 % without significantly damaging to the weather-resistance,
flow and mechanical properties. The moderate gloss coatings usually are application to lighting fixture, appliances, air
conditioner and office partitions and automobile parts.
2) Be enable to use in other coating systems such as pure epoxy and epoxy/polyester hybrid to provide these systems with
semi-gloss, smooth appearance and good non-yellowing properties.
3) This product belongs to adding type-Matting Agent without taking part in chemical reactions; thus the special design for
coating formulation is unnecessary. You are only selective for adding it at the premix stage of powder coatings. Varying its
added amount or selecting proper filler can adjust the gloss levels of the resultant coating, but the variable ranges usually
are limited.
4) May be as a modifier to improving coating surface hardness and anti-mar properties when desired at less than 1.0% based
on total formulation.
