Bresle Patches
274-PS002 Bresle Patches Plus (pack of 50)
Product Description
The Bresle Patches will allow you to extract for analysis, water-soluble salts and corrosion products from blast cleaned steel.
These compounds are almost colourless and are localized at the lowest point of the rust pits.
If they are not removed prior to painting, chemical reactions can result in blister formation and accumulations of rust that destroy the adhesion between the substrate and the applied protective coating
Bresle Test
274-P2005 Bresle Test. Includes 100 Bresle Patches
Product Description
The Bresle Test will measure contamination of water-soluble salts and corrosion products on blast-cleaned steel.
If these contaminants are not removed prior to painting, chemical reactions can result in blister formation and accumulations of rust that destroy the adhesion between the substrate and the applied protective coating.
Supplied in an industrial Carrying Case with 100 Bresle Patches, Conductivity Meter, 500ml Deionised Water, 3 × 5ml Syringes with Needles, Calibration Solution, Moistening Solution and Beaker. Conductivity Meter Calibration Certificate is an optional extra.
Dust Test
274-P4001 Dust Test. Includes Dust Test Tape & Dust Test Charts (pack of 50)
Product Description
Assess the quantity and size of dust particles on steel surfaces prepared for painting.
Dust particles on blast-cleaned steel surfaces may reduce the adhesion of applied coatings, and by absorbing moisture may promote the corrosion of the steel surface.
All items are supplied in an industrial Carrying Case with Dust Test Tape (60m roll), Dust Test Charts (pack of 50) and X10 Illuminated Magnifier.
Potassium Ferricyanide Test
274-P3001 Potassium Ferricyanide Test
Product Description
The Potassium Ferricyanide Test will enable detection of any water-soluble iron salts that form at the bottom of rust pits after blast-cleaning.
If these salts are present, they rapidly induce corrosion.
Additional packs of Potassium Ferricyanide Test Papers can be purchased to carry out further tests using this kit.
Supplied in a Carrying Case with 100 Potassium Ferricyanide Test Papers, Deionised Water Spray Bottle and Plastic Gloves.
