Iron
Phosphate
 We
operate a large capacity 2.5mØ Vixen
automated iron phosphate service with a 3 stage
wash cycle:
- hot
washing with a phosphate solution
- hot
rinsing
- hot
passivation solution
As
well as the large capacity 2.5mØ basket we can
undertake pre-treatment of much larger items using
the lance attachment.
Phosphate
Solution: The iron phosphate solution used is Novaphos
from Henkel which is a solution designed for the
conversion of iron, steel, aluminium and zinc surfaces
to a lightweight iron phosphate coating. The coating
conforms to BS3189 Type 4 and DEF STAN 03-11 Class
IV specifications.
Hot
Rinsing: The hot rinsing is a water solution with
synergic detergent additives.
Passivation
Solution: The final rinse contains Novaseal
350, a highly concentrated non-chromated solution which
provides a sealing action that improves paint adhesion
and extends resistance to humidity and salt spray.
