· Performance – Phos-Prep 971T is a zirconium/titanium based single-stage process, which runs like a conventional iron phosphate conversion coating. It has been shown in independent tests to provide up to a 1000 hours neutral salt spray on iron and steel, and 3000 hours on aluminium, when used with a rinse seal Phos-Prep 974.

· Introduction – A completely new chromium-free conversion coating. This clean technology product is a direct replacement for traditional pre-treatments on aluminium, mild steel and zinc based substrates.

· Applications – The product is suitable for either soak or spray application and as it is a single-stage process (the cleaning-stage is eliminated), reduces process time and cost, and increases throughput. The resultant conversion coat is resistant to high temperature accelerated adhesion tests.

· Case studies – Early users of Phos-Prep 971T include automotive components, shop fittings, medical cabinet manufacturers, powder coating subcontractors and architectural aluminium manufacturers. The conventional iron and zinc phosphate process has been replaced with this new clean technology process and have resulted in production benefits and improved surface coating performance.

· Unique chemistry – Phos-Prep 971T is accelerated and gives a very high conversion coating efficiency. This ensures minimal removal of material from the metal surface resulting in very low levels of sludge and a long bath life (up to three years) - Bath consumption is as much as 50% less than traditional phosphate baths. Only weekly checking and infrequent replenishment is required. Solution concentrations are easily controlled by simple titration. Due to the high efficiency of the product, energy requirements are also reduced. VOC, BOD and COD emissions are also minimised.
