From the largest man-made structures to the smallest household appliances, most manufactured products have a protective or cosmetic coating. Premature failure of this coating can, at the very least, result in costly penalties or rework.
Adhesion testing after the coating process will quantify the strength of the bond between substrate and coating, or between different coating layers or the cohesive strength of some substrates. Routine testing is used as part of inspection and maintenance procedures to help detect potential coating failures.
Elcometer offer a highly comprehensive range of Adhesion Gauges designed specifically to meet your requirements.
Cross Hatch / Cross Cut Method The coating is cut into small squares, thereby reducing lateral bonding, and the adhesion assessed against ISO, ASTM or Corporate Standards.

Advantages: |
A fast, low cost, comparison method -see table below |
Possible Limitations: |
A subjective test for flat surfaces for a limited thickness range. (250 mic)
|
Applications: |
For paint and powder coatings up to a thickness of 125 mic. (5mils) |

The coating may be continuous and look good, but how well is it connected to the substrate? The Elcometer 107 Cross Hatch Cutter provides an instant assessment of the quality of the bond to the substrate. Due to its rugged construction this gauge is ideal for thin, thick or tough coatings on flat or curved surfaces. An ideal field or laboratory testing. Conforms to ISO, ASTM, DIN, BS,EN & NFT.

Simple but effective method for determining the adhesion of a large variety of coatings. The instrument is ideal for testing the adhesion of thin coatings on flat surfaces using the cross cut method, available with three different spacings 1, 2, and 3mm, corresponding to the thickness of layer to be tested. Conforms to ISO, DIN, EN, NF, ASTM, BS, FCCA & NFT.
