Processing Guidelines
| Step | Process |
|---|---|
| Surface Preparation | Degrease then abrasive blasting to ensure adhesion |
| Filtration | 100-150 mesh stainless steel or nylon screen |
| Primer Application | Apply recommended primer via spray |
| Midcoat (Optional) | Apply midcoat if three-coat system is required |
| Topcoat Application | Apply 851G-224 Green topcoat via conventional or HVLP spray |
| Curing (Multi-Coat) | Preheat 49-60°C; bake each intermediate coat at 315°C for 5-10 minutes, cool and repeat until desired thickness; final coat cure at 399°C for 15 minutes |
Recommended Primers:
-
Use 850G-204, 850G-314, or 850G-321 as primer (mix with 850-7799)
-
855G-021, 857G-030, or 857G-040 primers are also compatible
Critical Processing Warnings:
Surface Preparation: Proper surface preparation is critical for adhesion. Ensure surfaces are clean, dry, and properly roughened.
Mixing: Use gentle rolling or tumbling only—do not use propeller-type mixers as coating is shear-sensitive.
Primer Selection: Select appropriate primer based on your application requirements and substrate.
Curing: Do not exceed 750°F. Cure time depends on part mass and oven characteristics.
Storage: Store in original, sealed containers in a cool, dry place away from direct sunlight. Prevent freezing.
Shelf Life: 18 months in unopened, clean, dry storage.
