Technical dataCodes, performance & application guidelines
Everything you need to read a Techno Plast shade code, choose the right chemistry and get the best result on your line.
Coding system
Understand the product from its code
Every shade code has 6 digits: the first two identify chemistry and finish, the last four identify the colour family.
| Product | Code | Finish | Description |
|---|---|---|---|
| Epoxy | 20 22 | Glossy Matt | High-performance epoxy powders with exceptional chemical resistance and protective properties. |
| Epoxy Polyester (Hybrid) | 30 32 38 40 42 | Glossy S/G (Satin) Matt STR (Structure) FT (Fine Texture) | General-purpose hybrid of epoxy and polyester resins with good chemical and corrosion resistance. |
| Pure Polyester | 50 52 57 58 59 | Glossy S/G (Satin) Matt STR (Structure) FT (Fine Texture) | Thermosetting polyester powders with excellent UV resistance, colour stability and weathering durability. |
| Polyurethane | 60 | PU types | Excellent chemical resistance, superior UV stability, high-gloss finish and strong adhesion to various substrates. |
| Metallic | 65 67 95 | Epoxy polyester special shade, crocodile shade Pure polyester metallic & other metallic | Metallic pigments — aluminium or mica flakes — for a shimmer-to-sparkle finish; crocodile effects for furniture and hardware. |
| Architectural | T-5 T-10 | 5-year SD 10-year SD (Super Durable) | Durable, decorative and weather-resistant architectural powders for long-life façades and profiles. |
| Primer | 80 | Zinc primer | Heavy-duty primer for highly corrosive environments; with polyester topcoat gives 3000 hrs neutral salt spray (corrosion <4 mm from scribe). |
| Fast Cure | 10 | FC type, low bake | Fully cured finish in a significantly shorter time at lower temperatures — ideal where rapid turnaround is critical. |
| Antibacterial | 62 63 | Anti-microbial Matt Anti-microbial Glossy | Kills bacteria and prevents growth of mould and fungi on coated surfaces. |
305003
Example: 305003 — RAL 9003 White Glossy
30 = Epoxy Polyester (Hybrid), Glossy · 5003 falls in 5000–5999 = White.
A “PP” suffix in a shade name means Pure Polyester.

Application
Guidelines for best performance
- Articles to be coated must be free from dust and grease and thoroughly cleaned. Iron or zinc phosphating is strongly recommended for better corrosion resistance.
- Powders are applied by corona charging equipment. Voltage may vary between 30–100 KV depending on the product.
- Metallic powders should be used with the charging voltage set to minimum. Recycled / recovered powder should be used with caution and care.
- Maintain film thickness as per manufacturer recommendation: structure finishes at 80–100 µm and plain solid shades at 50–90 µm, as per shade.
- Follow the curing cycle recommended by the manufacturer — typically 180°C for 10 min (hybrid) and 200°C for 10 min (pure polyester), metal temperature.
- Do not mix our products with those of other manufacturers.
Storage & handling
Keep powder at its best
- Store powders in a dry, cool area below 30°C.
- Validity / shelf life: six months from the date of manufacturing.
- Keep containers closed when not in use.
- For full details refer to the test certificate and MSDS supplied with each batch.
Powder coating process
- Part preparation / pre-treatment
- Powder application
- Curing — E.P. 180°C for 10 min, P.P. 200°C for 10 min (metal temperature)
