1. Product description
The standard epoxy-polyester hybrid for interior metal finishing, and the grade most general jobbing lines run as their base material. It holds colour better than straight epoxy through an overbake and tolerates a wider oven window, which matters when mixed part masses go through the same conveyor. Interior only: hybrid chalks outdoors in the same way epoxy does.
2. Features
- Holds colour through an overbake better than straight epoxy
- Wider oven window for mixed part masses on one conveyor
- 50 to 80 microns dry film
- Reclaimable
- Interior only: hybrid chalks outdoors as epoxy does
3. Recommended uses
General interior metal finishing on jobbing lines that run mixed part masses through the same conveyor oven, on steel, galvanised steel and aluminium.
Substrates. Pretreated mild steel, electrogalvanised and hot-dip galvanised steel, aluminium. Galvanised work is degassed before the powder is applied.
4. Typical properties
| Property | Typical value | Method |
|---|---|---|
| Technology | Thermosetting epoxy-polyester hybrid powder, solvent-free | Formulation |
| Appearance and finish | Fine, free-flowing powder; colour and gloss to order | Visual, against the agreed colour standard |
| Particle size distribution, d50 | 30 to 45 microns | ISO 8130-13, laser diffraction |
| Specific gravity | 1.2 to 1.8 g/cm3, set by pigment and filler loading | ISO 8130-2 or ISO 8130-3 |
| Gel time at 180 degrees C | 25 to 120 s | ISO 8130-6 |
| Inclined plate flow | 15 to 40 mm | ISO 8130-11 |
| Specular gloss | 5 to 95 gloss units at 60 degrees, to order; matt finishes read at 85 degrees and high gloss at 20 degrees | ISO 2813 |
| Adhesion | Cross-cut classification 0, no detachment, at 50 to 80 microns | ISO 2409 |
| Cupping and conical mandrel bend | 5 mm cupping and above without cracking; mandrel bend without cracking at the stated build | ISO 1520 and ISO 6860 |
| Neutral salt spray on pretreated steel | 500 to 1000 h, rated for rusting and blistering; pretreatment governs the result more than the powder does | ISO 9227, rated to ISO 4628-2 for blistering and ISO 4628-3 for rusting |
Typical values, not a specification. Values for each batch are given on its Certificate of Analysis.
5. Application
| Parameter | Guidance |
|---|---|
| Application method | Electrostatic corona or tribostatic spray |
| Surface preparation | Pretreated mild steel, electrogalvanised or hot-dip galvanised steel, or aluminium, clean and dry. Galvanised work is degassed before the powder is applied. |
| Dilution or thinner | None; applied as supplied, solvent-free |
| Dry film thickness | 50 to 80 microns, checked to ISO 2178 on steel and ISO 2360 on aluminium |
| Cure schedule | 10 to 15 min at 180 degrees C object temperature, confirmed with a data-logging oven profiler; oven air temperature is not the cure figure |
| Overspray | Reclaimable through the booth recovery system |
| Service | Interior only; not for parts exposed to sunlight |
Process. Electrostatic corona or tribostatic spray, 50 to 80 microns dry film. Typical cure 10 to 15 minutes at 180 degrees C object temperature. Reclaimable.
6. Storage and handling
Store sealed in the original packaging in a cool, dry place away from direct sunlight and heat sources, and let cartons reach workshop temperature before opening so that condensation does not form on the powder. Shelf life is stated on the label and Certificate of Analysis. Handle and use the product in line with its Safety Data Sheet.
7. Safety and regulatory information
Read the Safety Data Sheet before use. Safety Data Sheets and regulatory declarations are issued by our technical centre against the product and batch supplied, so they are sent on request rather than published. Request a Safety Data Sheet or declaration.
