PRE-TREATMENT - Steel

This five-step process includes:

  1. Cleaning and de-greasing with a hot pressurized spray of Bulk kleen 842= is a liquid free rinsing alkaline (pH 12) cleaning agent. It is designed expressly for the cleaning of steel, zinc and aluminum parts moreover its low foam makes it suitable for use in spray washing.
  2. High pressure water rinse.
  3. Iron Phosphate conversion coating of : Kote 63LS an acid (pH 4) is a dual purpose, liquid chemical which simultaneously cleans and produces an Iron Phosphate coating on ferrous metal surfaces.
  4. High pressure water rinse
  5. DI water rinse

Pre-Treatment – Aluminum

This six-step Process, includes:

  1. Cleaning and de-greasing with a hot pressurized spray of Bulk kleen 842= is a liquid free rinsing alkaline (pH 12) cleaning agent. It is designed expressly for the cleaning of steel, zinc and aluminum parts moreover its low foam makes it suitable for use in spray washing.
  2. High pressure water rinse
  3. Iron Phosphate conversion coating of : Kote 63LS an acid (pH 4) is a dual purpose, liquid chemical which Simultaneously cleans and produces an Iron Phosphate coating on ferrous metal surfaces.
  4. High pressure water rinse.
  5. Low pressure DI water rinse
  6. Seal rinse with E-CPLS 2100 = is a non-chromate, non-phosphate liquid chemical used to produce on aluminum and zinc alloys a clear nearly colorless chemical conversion coating.

Pre-Treatment Automatic Spray (CONVEYOR)

Suspended parts are moved by overhead conveyor through a high walled U shape structure where conditioning solutions and rinses are directed onto the parts by fixed spray nozzles.

Cleaning and Phosphate is accomplished in a single step using a mixture of Kote 52= Is a Dual purpose, powdered chemicals which simultaneously clean and produce an Iron Phosphate Coating on ferrous metal surfaces at low 140*F temperature water. Followed by Hi pressure water rinse and final low pressure water rinse.

Coating powders are 100% nonvolatile, solid particulate, and have no measurable vapor pressure. Therefore, with the possible exceptions of blocking agents released during curing and certain products of condensation reactions, there are no volatile vapors associated with their application and use.
