Thixotropic Pickling Paste for Stainless Steel
Conforms to ASTM a380-06 Standard Practice for Cleaning, Descaling and Passivation of Stainless Steel Parts, Equipment, and Systems
DESCRIPTION
Weldbrite utilises innovative Australian technology for the formulation of a high adhesion stainless steel pickling gel for pickling applications It is used to remove the black oxide marks or burn scale left during welding of stainless steel.
This product conforms to the international standard, ASTM A380-06. The standard practice for cleaning, descaling & passivation of stainless steel parts, equipment & systems.
After use of Weldbrite the weld area should have the same look as the rest of the steel being used. Weldbrite leaves a clean professionally finished stainless steel weld area, free from contamination.
PHYSICAL PROPERTIES
Boiling Point : N/A
Specific Gravity : 1.15
Water Solubility : Miscible
pH (as supplied) : < 1.0
Appearance & Colour : Opaque, white acidic gel, pungent acidic odour
BENEFITS
* Quick acting
* One step treatment
* Completely water rinseable
* Convenient size packs - no wastage
* Can be used on vertical surfaces
DIRECTIONS FOR USE
1. Clean the weld area carefully using a stainless-steel brush.
2. Roll or shake the drum of Weldbrite if possible for 30 seconds prior to opening the container to ensure a smooth consistency, especially if the product has not been used for a long time.
3. After welding ensure the area to be pickled has sufficient time to cool below 40OC.
4. Apply the Weldbrite gel to the area to be cleaned, using the brush provided or with an acid resistant spray pump and applicator. DO NOT PICKLE IN DIRECT SUNLIGHT.
5. Application times may vary depending on ambient temperature, the grade of stainless, surface finish or the method of welding. On a hot rolled surface the pickling time may increase by 50%. MIG welds may require longer pickling times than those obtained using covered electrodes. Allow the pickling gel or solution sufficient time to react with the surface. With high ambient temperatures or when longer pickling times are required it may be necessary to repeat the process. Should the product dry on the surface wash down, dry and repeat the process.
PACKAGE SIZES
Weldbrite is available in 20kg or 230kg drums - smaller 1.0kg, 2.5kg jars are available for brush application where required.
SAFETY PRECAUTIONS
Caution: This product contains Hydrofluoric Acid and Nitric Acid and is corrosive and toxic.
Wear appropriate clothing, i.e. full body protection, breathing apparatus, face shield, gloves, boots etc.
Do not use Weldbrite near open flames or cutting torches, since a hazardous flammable gas can be generated. Keep lid tightly closed when not in use. Store in a cool, dry spot away from direct sunlight. Keep out of reach of children. If used in poorly ventilated areas, use a respirator equipped with a chlorine type filter.
If you have to neutralise the Weldbrite residue this can be done using S-Weld Neutralizer neutralising solution. Add S-Weld Neutralizer neutralising solution until the colour remains a pale pink colour.
