The device determines the adhesion and scratch resistance of coatings by using a cutting unit with interchangeable indenter tips that apply a controlled load, allowing for assessment of the coating’s resistance from superficial marks to complete destruction based on modern quality standards for mechanical resistance.
Scratch hardness coating tester measures the hardness of various coatings by assessing their resistance to indentation from a 1 mm ball tip, and can be used on uneven or curved surfaces; it is lightweight, portable, and allows users to adjust the load force by changing spring tension.
The instrument tests the hardness of powder and liquid paint coatings using sharpened pencil leads at a 90° angle, starting with the softest leads and increasing hardness until damage appears; the hardest lead that leaves no marks indicates the coating’s hardness value (e.g., 3H, 2H, H, HB, B, 2B, etc.).
The Buchholz coating hardness tester measures coating hardness through an indentation method using a 500g stainless steel disc, with the indentation length measured after 30 seconds using a microscope to provide results in Buchholz indentation resistance units.
The Erichsen stamp measures the elasticity and strength of coatings by indenting a 20 mm diameter spherical tip into a coated sample secured in a 27 mm diameter matrix, providing an effective assessment of the coating’s quality, adhesion, and elasticity.
The impact tester features a multipurpose design with a stand, clamping device, and customizable impact devices (striker, clutch, and anvil) that meet various standards, allowing for testing across multiple standards.
Impact tester is intended for testing the strength of coatings upon impact on pipelines during their installation and operation. Device allows testing directly on the pipeline and does not require the manufacture of samples.
The device NOVOTEST IMPACT COATING STRENGTH Tester is used to check the resistance of technical products to external factors during operation (such as punching, impacts), as well as verification of manufacturer’s specifications.
The instrument evaluates the elasticity and flexural strength of coatings by bending the sample around cylindrical rods with diameters ranging from 1 mm to 20 mm, determining the smallest rod diameter that doesn’t cause mechanical damage or delamination of the coating.
The instrument measures the elasticity and flexural strength of coatings by bending the sample around cylindrical rods with diameters ranging from 6 mm to 25 mm, determining the smallest rod diameter that avoids mechanical damage or delamination of the paint film.
The device measures the elasticity and strength of coatings by bending a coated metal plate around cylindrical rods ranging from 2 mm to 32 mm in diameter, determining the smallest rod diameter that prevents mechanical damage or delamination.
The device measures the elasticity and strength of coatings by bending a coated metal plate around a conical mandrel using a roller on a hand-operated lever, determining the minimum mandrel diameter at which the coating starts to crack, as indicated on a scale (3-37 mm) on the sample clamp.
