INTRODUCTION
OXYPLAST PR16 is a satin-matt thermosetting powder coating based on saturated polyester resins specially selected for exterior use. It’s very good flow-out and excellent resistance to atmospheric ageing and ultra-violet light make it highly decorative and durable in outdoor environments. This high performance has been proven through many years of service in various applications.
GLOSS AND COLOUR RANGE
Gloss levels range from matt to satin: 15 - 35% at 60⁰. A full colour range is available; with the whites and very light shades showing slight overbake yellowing.
APPLICATIONS
Include architectural hardware, ceiling panels, outdoor furniture, lamp posts, signboards, etc.
APPLICATION SCHEDULE
May be applied by electrostatic spraying using classic devices which can provide a negative tension of 60 - 80kV. The powder is cured in a suitable convection or infra-red oven. Curing: Medium cure 10 mins at 200⁰C Optimal film thickness: 60 - 80µm.
SUBSTRATES AND PRE-TREATMENT
May be applied to the following substrates after the appropriate cleaning and conversion coating:
Ferrous metals (cold-rolled steel, cast iron, etc.) : Iron or zinc phosphatation
Zinc surfaces (galvanised steel, zinc alloy) : Chromatation or zinc phosphatation
Aluminium alloys : Aluminium alloys
STORAGE
At temperatures not exceeding 25⁰C and under dry conditions, PR16 powders may be stored for up to 6 months without affecting their free-flowing properties. The coating thus obtained will still have optimal characteristics.
PROPERTIES OF THE POWDER
Melting range (Kofler) : 75 - 115⁰C
Specific gravity (DIN 55990/3) Particle size distribution, : 1.25 – 1.75 (depending on colour)
