HF-68 is non-reactive wax-free based Matting Agent designed for Epoxy –Polyester hybrid powder coating to provide 10%
Epoxy/hybrid matt hardeners are commonly used in powder coatings to provide a durable and attractive finish. These
hardeners are typically a blend of epoxy resins and curing agents that work together to chemically crosslink and cure the
powder coating.
The epoxy component of the hardener provides excellent adhesion and chemical resistance, while the curing agent initiates
the crosslinking reaction to harden the coating. This results in a tough and durable finish that is resistant to impacts, abrasion,
and chemicals.
The use of a Matt Hardener in powder coatings helps to achieve a matte or satin finish, rather than a glossy one. This is desirable
for certain applications where a non-reflective or textured appearance is desired.
In addition to providing a matt finish, epoxy/hybrid matt hardeners also improve the overall performance of the powder coating.
They enhance the coating's resistance to UV degradation, weathering, and corrosion. They also improve the coating's mechanical properties, such as hardness, flexibility, and impact resistance.
Overall, epoxy/hybrid matt hardeners are an important component in powder coatings, providing both aesthetic and functional
benefits.
