Home » Products » Surface Preparation » Surface Cleanliness / Salt Detection

Salt Detection is a way of testing for Surface Cleanliness. Surface contamination from salts such as chlorides, sulphates and nitrates have been shown to lead to blistering of organic coatings, particularly in immersion conditions.

It is not sufficient to measure the cleanliness of the substrate. In a multi-layer coating process, it is necessary to monitor and record the cleanliness of each layer prior to applying the next coating.

When using amine cured epoxy coatings, for example, in low ambient temperatures or in high humidity, a surface oiliness or exudate may cause inter-coating adhesion failure.

Surface cleanliness: Soluble salts & ion specific contamination (sulphates, chlorides, nitrates etc.) which are often invisible to the eye, together with amine blush (for amine cured epoxy coatings) can result in premature coating failure, resulting in high re-coating and maintenance costs. Elcometer and BAMR have a range of test equipment for assessing surface cleanliness prior to applying a coating.

The type of tests can be split into:

high up front costs and low cost per test.

The Elcometer 130 and the Soluble Salt Meter SSM are examples of these units

relatively low up front costs but cost per test is high

The Elcometer 138 and the Elcometer 134 are examples of these

Elcometer 130 SSP Soluble Salt Profiler

by Helena Duk | posted in: Products, Surface Cleanliness / Salt Detection, Surface Preparation | 0

The Elcometer 130 SSP Soluble Salt Profiler provides fast and accurate measurement of the level and density of soluble salts – over 4 times faster than other Bresle equivalent methods. The new Elcometer 130 SSP allows you to complete a Bresle equivalent test in just over two minutes. The multi-point conductivity sensors enable the Elcometer 130 SSP to accurately display salt concentration, showing exactly where the contamination lies and generating full colour salt density maps in 2D or 3D.

Elcometer 145 Dust Tape Roller

by Graham Duk | posted in: Coating Inspection, Products, Surface Cleanliness / Salt Detection, Surface Preparation | 0

The Elcometer 145 is used in conjunction with the Elcometer 142 Dust Tape Test kit, to assess the quantity and size of dust particles on surfaces prepared for painting. The Dust Tape Roller presses the Elcometer 142 Dust Tape to the surface using a controlled constant force as required by BS EN ISO 8502-3 (BS 7079-B3:1993). It removes the subjective nature of a person trying to apply an even force to the tape and will result in a more objective result … Read More

Elcometer 142 ISO 8502-3 Dust Tape Test kit

by Graham Duk | posted in: Coating Inspection, Products, Surface Cleanliness / Salt Detection, Surface Preparation | 0

The Elcometer 142 Dust Tape Test Kit allows assessment of the quantity and size of dust particles on surfaces prepared for painting. Dust on blast cleaned surfaces can reduce coating adhesion, leading to premature coating failure and sub-standard coating finish. The kit can be used in accordance with the recommendations of BS EN ISO 8502-3 either as a pass/fail test or as a permanent record of the presence of dust. Supplied in a carry case for use in the field … Read More
