Application Guide: Power Coating
Industrial powder coatings are 100% solid coatings that are based on formulations
composed of thermoset resins, curing agents, fillers, pigments, and other additives. Fillers
reduce sag, provide reinforcement, reduce UV degradation, and improve moisture and
corrosion resistance. Both decorative and functional powder coatings can successfully
utilize functional fillers.
Wollastonite with low to moderate aspect ratio (5:1 to 9:1) provides superior appearance with
very good flow properties. Gloss control is generally the first observation.
Wollastonite can be used to substitute for part of the hardener to create flattening.
Wollastonite is not recommended in high gloss applications.
Wollastonite can be used to create special effects and in some cases surface treatment
chemistries can be advantageous.
Resins and formulations can vary. An important factor is intended use of the powder, for
functional or decorative applications. Contact Fibertec for specific grades, surface
treatments, and technical assistance.
