Natech Ltd Product Data Sheet

Natech N20 Natech N20 is a completely phosphate and transition metal free conversion coating for use on aluminium extrusions, aluminium and white metal engineered parts, aluminium coil, steel , galvanised steel , aluzinc and zinctec to greatly enhance corrosion protection and adhesion of subsequently applied coatings. The product gives a very high conversion coating efficiency. This ensures the absolute minimum removal of metal during conversion coating, which gives low levels of sludge and long bath life. N20 is a fully built product and cleans and conversion coats in a single stage, greatly reducing process times and cost. Product concentrations are easily controlled by simple titration or by conductivity. The resulting conversion coats are resistant to high temperature accelerated adhesion tests - heating in water to 125C for 2 hours gives no loss of topcoat adhesion. N20 is suitable for soak or spray application.

TYPICAL PROPERTIES Appearance Very pale straw coloured, clear liquid

PH Concentrate is pH 1.5 to 2.5% Freeze/thaw stability Freezes at <OC, and reconstitutes upon thawing

Parameter Recommended range Concen tra tion 0.5% tol%

Temperature 20 to 30C Time 30 seconds to 2 minutes, depending upon coating weight required

RECOMMENDATIONS FOR USE Strength determination The concentration of the bath is maintained by monitoring the levels of total and free

and control acid. N20 is internally self-buffering, and if the concentration is maintained within the recommended range, then the pH will adjust to the correct value (pH 3.0 to 6.0 depending upon running concentration). Baths of N20 are best controlled either using a simple acid/base titration or a conductivity meter and auto-dosing pump. Natech technical support will empirically set specific operating parameters for your requirements, and supply details of titration procedures.

Plant and equipment All process tanks, piping pumps and heat transfer surfaces should be fabricated from mild steel, stainless steel, or polypropylene

Spillage and Disposal Small spills may be washed to waste with plenty of water. Larger spills should be contained and neutralised with soda ash or builders lime before washing to waste or sweeping up for disposal. Used solutions can normally be dumped to foul sewer but may be contaminated with material from parts that have been processed. Seek guidance from Natech

HEALTH AND SAFETY

N20 is irritating to eyes and skin. [n case of contact with skin, wash thoroughly with plenty of water. [n case of contact with eyes, rinse immediately with plenty of water and seek medical attention.

Product Data Sheet

Koiseal MO

Kolseal MO is an additive for the final rinse of a spray or immersion iron phosphate line to inhibit the parts that have been phosphated against corrosion prior to painting. The use of Kolseal MO may be required where there is a possibility of a delay between pre treatment and painting. The product is suitable for use on steel, aluminium and zinc surfaces, and imparts flash corrosion resistance to all these substrates . Kolseal MO also increases considerably the long-term corrosion resistance of parts that have been iron phosphated, and gives much better salt spray results than parts that have been phosphated only. Kolseal MO is economic in use, and easily controlled

TYPICAL PROPERTIES

TYPE Amine based rinse additive. Enhances corrosion protection and prevents flash rusting

APPEARANCE Clear to straw liquid

SG Typically 1.2 to 1.3

SOLUBILITY 100% miscible with water

RECOMMENDATIONS FOR USE

CONCENTRATION 0.3% to 0.5 % by volume TEMPERATURE Ambient pH 4 to 6 depending upon concentration TIME 30 seconds to 2 minutes

Bath life depends on the work load, tank size etc. Concentration can be measured by simple titration and additions made manually as required. Alternatively, bath additions can be made automatically using auto dosing equipment.

HEALTH AND SAFETY

There are no special storage requirements for this product. When handling the product, protective PVC gloves, apron and goggles to BS 2092C should be worn. In the event of spillage or contact with skin or clothing, drench with plenty of water. In case of eye contact, rinse immediately with plenty of water and seek medical advice . For further information, please refer to the Natech MSDS sheet.
