What is oven-cured coating?
A hard, seamless finish formed by heat
Oven-cured coatings are finishes that are baked in an oven after application to form a hard, uniform and durable film. The best-known type is electrostatic powder coating for metal parts: a dry powder of resin, pigment and additives is charged by an electrostatic spray gun and attracted to the grounded part.
The metal part then enters a curing oven where, at around 180–200 °C, the powder melts, flows out and cures into a continuous film. There are no solvents, so VOC emissions are close to zero and overspray can be collected and reused.
Plastic and polymer parts can't take that heat and would deform. They are painted with plastic-specific paints usually two-component (2K) polyurethane, acrylic or waterborne systems cured at low temperature, around 60–80 °C. The key to durability is adhesion: low-energy polymers such as PP and PE are activated by flame or plasma treatment and primed accordingly.
Either way, the result is a uniform surface with excellent resistance to scratches, impact, moisture, chemicals and sunlight.

Six steps to a flawless finish
A great finish is made before the first spray. Every step is tuned to the material and to the paint manufacturer's specifications.
- 01
Consultation & inspection
We review the material (metal, plastic or Bakelite), size, environment and the colour and effect you want, then choose the right paint and pretreatment; new parts get an adhesion test on a sample.
- 02
Surface preparation
Metal: degreasing, rust and paint removal, sandblasting and, where needed, phosphating. Plastic: washing, removal of mould-release agents, anti-static treatment, flame or plasma activation and an adhesion primer.
- 03
Application
Metal parts are powder coated with electrostatic guns; plastic parts are sprayed with plastic-specific paints in a clean, dust-free booth evenly, with no runs or brush marks.
- 04
Oven curing
Each part is cured for the right time at a temperature matched to its material from 60 to 200 °C so the coating fully cures and reaches final hardness without warping.
- 05
Quality control
Every layer's thickness is measured, and adhesion (cross-cut test), colour uniformity, gloss and the match to the approved sample are inspected before release.
- 06
Packing & delivery
Once cooled, parts are packed with protective wrapping so they arrive without a scratch.

Why oven-cured coating
Advantages over conventional paint
Tough & durable
A hard yet flexible film that resists impact, abrasion, scratches, cleaning agents and chipping far better than ordinary paint.
Protection & a flawless surface
On metal, proper prep and phosphating protect against corrosion; on plastic, one uniform coat hides flow lines, weld lines and colour streaks from moulding.
Lower-emission options
Powder coating is solvent-free with near-zero VOCs, and plastics can use waterborne, low-VOC paints with an energy-saving low-temperature cure.
Your exact brand colour
Colour matched to RAL, Pantone or a physical sample consistent even across parts made from different materials.
Economical for many colours
For plastic parts, instead of changing masterbatch and purging the moulding machine for every colour, mould in one base colour and paint in several.
Ready for assembly sooner
Oven curing shortens drying time, so parts reach your assembly line faster even on high-volume orders.

FAQ
Common questions about oven-cured coating
What is oven-cured coating and how is it different from regular paint?
It's a coating that is baked in an oven after application. On metal, solvent-free electrostatic powder coating cures at around 180–200 °C; on plastic, special paints cure at low temperature. The result is a more uniform and far more durable film than ordinary paint, with better resistance to impact, scratches, moisture and sunlight.
Can plastic parts be oven-cured coated?
Yes but not with ordinary metal powder coating. Plastic parts are painted with plastic-specific paints such as two-component polyurethane and cured at low temperature, around 60–80 °C, so the part doesn't deform.
Which plastics and polymers do you coat?
Saro Coating paints PP (polypropylene), PE (polyethylene), PA (polyamide/nylon PA6, PA66 and PA46, including 10% and 30% glass-fibre-reinforced grades), ABS, PC (polycarbonate), PC/ABS blends and Bakelite. For other polymers we advise after an adhesion test on a sample.
How durable is oven-cured coating?
It depends on surface preparation, the coating and the environment. On metal, with proper blasting or phosphating and an outdoor-grade polyester powder, the finish lasts for years without peeling. On plastic, with surface activation and the right paint system, it won't peel in everyday use; for high-touch surfaces we recommend a scratch-resistant clear coat.
Epoxy vs polyester powder what's the difference?
Epoxy offers excellent adhesion and chemical resistance but chalks under sunlight, so it suits indoor and industrial parts. Polyester resists UV and weathering and is the go-to for outdoor metal parts.
Do you offer vacuum metallizing and chrome on plastic?
Yes. Vacuum metallizing gives plastic parts a gloss chrome, matte chrome or Fantachrome (tinted chrome) finish, sealed with a protective lacquer for durability. Hydrographics in a range of patterns and an anodised look in matte or gloss colours are also available.
Can you match our exact colour?
Yes. The colour is mixed to your RAL code, Pantone reference or physical sample, and a painted sample is prepared for your approval before production.
How is the price calculated?
Price depends on part size, quantity, material, the preparation and primer needed, number of coats and the effect (e.g. soft-touch, metallic or vacuum metallizing). Send a photo, dimensions, quantity and colour on WhatsApp for an accurate quote.
What's the minimum order and lead time?
We take both sampling and high-volume orders and aim for the shortest lead time at the best quality. Exact timing depends on quantity, preparation and colour and is confirmed when you order on WhatsApp.
