Pretreatment and Cleaning

(Click on each process to learn more.)

Stage 1-Alkaline Cleaner
Stage 2-Alkaline Cleaner
- Having 2 cleaning stages allows the ability for independent heating zones, double cleaning, and the versatility of running a “hotter” stage or putting a cleaning booster for processing extremely dirty parts.
Stage 3-Rinse
Stage 4-Rinse
- 2 Rinse stages give double protection for removing any soils and alkaline residue so the conditioner and zinc phosphate stages can have full and immediate reaction with the surface material.
Stage 5-Acid Pickle

This stage is an optional stage used to remove scale and light rust. This stage can only be used on Steel due to the acid involved.

Stages 6 & 7 are double rinses after the pickle stage.
Stage 8-Rise Conditioner
- The conditioner stage is used prior to the zinc phosphate to promote a heavier and more uniform phosphate film build.
Stage 9-Zinc Phosphate Bath
- Zinc phosphate is a crystalline in structure, providing excellent adhesion. Zinc coating weights range from 300 to 400 milligrams per square foot giving superior corrosion resistance. Zinc Phosphate can provide up to 3000 hour salt spray.
- Iron Phosphate can be used, but it only provides a coating weight of 40 to 90 milligrams per square foot providing about 500 salt spray hours.
Stage 10-Zinc Phosphate Rinse
- Rinses excess phosphate off parts and prepares the surface for the sealer.
Stage 11-Sealer
- Non-Chrome sealer adds corrosion resistance.
Stage 12-Reverse Osmosis Rinse
Stage 13-Reverse Osmosis Rinse
- The RO water baths rinse parts in an ultra clean rinse before paint. These rinses are filtered continually using Bag filters.
