Chemical grade matt hardeners for powder coating are additives that are used to create a matte or satin finish on the
surface of powder-coated objects. These hardeners are typically mixed into the powder coating formulation before it is
applied to the object.
Chemical grade matt hardeners are designed to enhance the hardness and durability of the powder coating while also
providing a smooth and matte finish. They help to reduce the glossiness of the coating, resulting in a more subdued and
muted appearance.
These hardeners are typically made from a combination of resins, curing agents, and other additives. They are formulated
to be compatible with various types of powder coatings, including epoxy, polyester, and hybrid formulations.
When using a chemical grade Matt Hardener, it is important to follow the manufacturer's instructions for proper mixing and
application. The amount of hardener needed will depend on the desired level of matte finish and the specific powder coating
formulation being used.
Overall, chemical grade matt hardeners are a useful tool for achieving a matte or satin finish on powder-coated objects. They
provide enhanced durability and a unique aesthetic, making them a popular choice for a variety of applications.

Application
1.HF-68 can be applied in epoxy powder system to generate the strong matte effect, terrific leveling performance and stable comprehensive properties. It can be used for pure epoxy and epoxy/polyester hybrid powder systems as a hardener, preparing coatings with super matte surface, excellent mechanical property and good reproducibility characteristic.
2. Pre-mix and Co-extrusion [One-Shot Method]
Advantage
1. One-shot effect:No dry-blending is required.
2. Durability:Very good weathering resistances
3. It has good color stability & mechanical properties, as well as good stability both during processing and storage.
