These powders are available in many different particle size distributions and formulations to allow application by common powder coating methods used today. A wide variety of colors are available through dry blend or melt-mix coloration. The melt-mix (mass coloration) process produces a stable finish and superior UV stability compared to dry blended grades. Special grades and color-matched formulations can be developed specifically to suit customer needs.
For Fluid Bed Dipping...
Rilsan® T
Rilsan® T grades are designed for the fluidized bed dip coating process. A coating thickness between 250 to 500 μm is typical.
*The 'T' comes from the French word "trempage," which translates to "dipping" in English. Rilsan® T grades are sometimes referred to as Rilsan® FB for Fluid Bed.
For Electrostatic Spraying...
Rilsan® ES and Rilsan® ESY
These product ranges are designed for the electrostatic spraying process using positive, negative or “tribo” guns.
Positive polarity is recommended for Rilsan® ES grades. Rilsan® ESY powders are specially formulated with a built-in adhesion promoter to improve adhesion on the substrate. ESY powders do not require primer, except when very durable corrosion resistance is needed. The recommended coating thickness is between 100 and 150µm.
For Minicoating...
Rilsan® MC
Rilsan® MC grades are specifically designed for the coating of small items via the minicoat/maxicoat process, which was originally developed by Arkema. The coating thickness is typically between 170 and 300 µm.
Primers...
Primgreen and Rilprim
Two high performance primers are commercially available: Primgreen (water-borne, low VOC) and Rilprim (solvent-based) primers. These primers have been specifically developed to be compatible with Rilsan® Fine Powder coatings on a variety of metal substrates and at various processing temperatures. Using primers helps provide the best anticorrosion properties attainable when combined with Rilsan® PA11 coatings.
For Extra Grip & Flexibility...
Pebax® Fine Powders
For applications requiring a high flexibility coating, Pebax® Fine Powders can be selected. This product is a thermoplastic elastomer that behaves like an elastomer. The Pebax® coating provides excellent grip property, with a good adhesion on smooth surface, and a good UV resistance.
