NK mending mandrels by NEURTEK are the benchmark equipment for assessing the flexibility and adhesion of organic and inorganic coatings on metallic substrates through bending tests.
Designed and manufactured entirely by NEURTEK, they are available in two versions — cylindrical and conical — which comply with the main international standards and are suited to different testing requirements.
The test involves bending a coated test specimen over the mandrel and observing the appearance of cracks or loss of coating adhesion. The result allows for an objective comparison of the ductility and flexibility of different coating systems or application processes.
