|Product Code:||Elcometer 506|
The Elcometer 506 are lightweight, portable and easy-to-use adhesion testers available in analogue or digital gagues and are suitable for measuring the pull-off adhesion of coatings up to 50MPa (7250psi) either on-site, or in the laboratory.
The design of the Elcometer 506 adhesion testers ensures that a uniform force can be easily applied throughout the range by smoothly rotating the gauge's crank handle, ensuring repeatable results to an accuracy of ±1%.
The Elcometer 506 adhesion tester's quick connect coupling allows the simple attachment of 14.2mm, 20mm or 50mm diameter dollies which, together with a wide range of accessories, allows coating adhesion testing on flat, curved, thick and thin substrates - including metal, wood, concrete and other fibrous materials.
The Elcometer 506 test head (actuator) has been designed to be small, ergonomic and lightweight – ideal for single handed testing of coating adhesion even in awkward or confined spaces.
Safe adhesion testing on vertical surfaces has also been considered. Using the magnetic clamp accessory the actuator is held securely - preventing accidental damage to the surrounding areas.
|Testing coatings on concrete & low bond strength substrates|
When testing coatings on low bond strength substrates such as concrete, wood or other fibrous materials, a larger surface area of dolly is required to improve accuracy, repeatability and reproducability.
The Elcometer 506 Concrete Adhesion Tester can be supplied as a kit or with individual 50mm accessory items (skirt, dolly, cutter) which can be added to existing Elcometer 506 gauges.
|How to Prevent Adhesive and Cohesive Failures|
|Preparing the surface and dolly|
|Fixing the dolly|
|Assessment of the Adhesion Test|
For a valid pull test the coating must cover at least 50% of the area of the dolly face. If the glue fails and no coating is present on the dolly, or it covers less than 50% of the dolly face area, the pull-test is invalid and should be repeated.
When the coating has failed within the layer leaving the same coating on both the dolly and the test panel it is known as a "cohesive failure".
"Adhesive failures" occur when either the coating has failed at the interface with another coating (leaving a coating on the dolly and another coating on the substrate), or when the coating has failed at the substrate (leaving the coating on the dolly and the substrate is bare).
|NOTE: If the glue fails at a value above the specification then it can be reported that the adhesion exceeded the specification for this individual test.|
