adhesion - cross hatch, pull off & push off testers
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. The gauges can be split into three categories:
| 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. |
| Pull Off Adhesion Method |
Tensile Dollies (or stubs) are glued to the coating and, when the adhesive has cured, the force required to pull the dolly off the surface is measured. |
| Push Off Adhesion Method |
Similar to the Pull Off Adhesion Test, a dolly is glued to the coating. When the adhesive has cured, however, the dolly is pushed off the surface by the adhesion gauge. |

Elcometer 1541 Single Blade Cutter
This instrument has a single-blade tool used to perform simple parallel or crossed cuts on plane or curved surfaces. Ideal for the St Andrews Cut method. |
 |
|
Elcometer 1540 Cross Cut Tester
Simple instrument for quickly determining the adhesion of a large variety of paints. Made from special steel, it has 11 tapered teeth with 1mm spacing. Two series of lines are cut at right angles to obtain a pattern of 100 squares. |
 |
|
Elcometer 1542 Cross Hatch Adhesion Tester
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. |

|
Elcometer 107 Cross Hatch Cutter
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 test. |
 |
|
Elcometer 108 Hydraulic Adhesion Tester
An extremely versatile hydraulic adhesion tester which will cope with many adhesion test requirements. Test can be made on flat or curved (concave and convex) surfaces. A reusable dolly is adhered to the coating's surface and the force required to push the dolly from the surface is applied using the handle. The value of the force applied is displayed either on a digital display or on an analogue dial. |

Elcometer 106 Pull Off Adhesion Gauge
Perhaps the best known adhesion gage on the market today. The Elcometer 106 adhesion tester is easy to operate and fully portable, providing a numerical value for adhesion. Supplied in a rugged carry case for moving around the jobsite, the unit is hand operated so you don't have to worry about a power supply! |
 |
|
Elcometer 106/6 Coatings on Concrete Adhesion Tester
The Elcometer 106/6 Adhesion Tester has been specifically designed to measure coatings on concrete. Operating in a similar way to the regular Elcometer 106 Adhesion Testers, the Elcometer 106/6 allows for a 50mm (2) diameter dolly for testing coatings on concrete. |
 |
|
Elcometer 109 Tensile Adhesion Tester
The Elcometer 109 Push off Tensile Adhesion Tester provides the operator with a means of carrying out a simple pass/fail test of the adhesion of the coating against a specification limit. If the coating bond is greater than the dolly rating, the dolly breaks - not your coating - thus becomming a 'non-destructive' test. |
 |
|
Elcometer 110 Pneumatic Adhesion Tester
The Elcometer 110 PattiŽ is a portable pneumatic adhesion tester which uses compressed gas from either a canister or the compressed air feed. Due to the controlled force being applied, the resultant adhesion value is highly repeatable. This, together with the gauge's suitability on thin substrates provides the User with an ideal testing instrument in the laboratory or the field. |

Elcometer 1910 PAT™ Handy Adhesion Gauge
This lightweight, portable, hydraulic adhesion tester has built in hydraulic safety devices for smooth and drift proof accuracy. The special test head allows adhesion tests on both internal and external curved surfaces, making this an ideal gauge for pipelines and protective coatings applications. |
 |
|
Elcometer 1920 PAT ™ AT101 Adhesion Tester
This automatic adhesion tester is designed for measuring the bond strength of all types of paints, thermal sprayed coatings, thin films, concrete coatings and much, much more, on any shaped substrate. A dolly is adhered to the surface and once the test head is connected, a tensile force is applied. The rate of application can be adjusted by the User. |
 |
|

|
Elcometer 1980 PAT ™ Coating Fracture Tester
Comprising of two cylinders of 25mm (1) diameter, the Elcometer 1980 is designed to measure the force required to fracture a coating. One cylinder is coated with the sample coating, and the two cylinders are glued together. The cylinders are then pulled apart in order to measure the pull stress (in Newton/mm 2 or PSI) required to fracture the coating. |
 |
|
