Cross Cut Adhesion Tester NOVOTEST AN-2409
Cross Cut Adhesion Tester NOVOTEST AN-2409 is designed to determine the adhesión (adhesive force) by method cuts (parallel or grid) with thicknesses paint to 200 µs, according to ISO 2409, ISO 16276-2, ASTM B 3359. It can be used on flat and curved surfaces.
The method of parallel or lattice cuts is to assess the adhesion values while cutting through the coating down to the substrate by multiblade knife with the distance between the blades 1 mm, 2 mm and 3 mm. This produces a strip or grating with the same pitch. The place of cutting is cleaned and visually analyzed the value of adhesion by the nature and the area of destruction of the coating. Each knife has six main and two restrictive blades. User can sharpen blunt blades.
Advantages of NOVOTEST AN-2409: Simplicity, usability, reliability and durability.
Tensile Adhesion Tester NOVOTEST AC-4624
Adhesion of separated type is designed to control adhesion (traction), paints and other coatings to the base and between the layers and cohesive materials. Tensile Adhesion Tester NOVOTEST AC-4624 is manufactured according to ISO 4624.
Available options of Tensile Adhesion Tester NOVOTEST AC-4624:
• Fungus
• Two-component epoxy adhesive
• CA glue
Advanteges
- Simple design and easy to work with adhesion allow it to become a daily means of operational control of adhesion.
- The using glue with fast curing base allows user to measure the adhesion in shorter timeframe.
Cross Hatch Adhesion Plate NOVOTEST AH-16276
Cross Hatch Adhesion Plate NOVOTEST AH-16276 is designed to measure the adhesion value of coatings. Cross Hatch Adhesion Plate NOVOTEST AH-16276 consist of a flat steel plate with normalized slits, which is used as a template to perform incisions with the knife.
Application
The adhesion plate is placed on the test surface, the coating is cut with the knife up to the substrate, after which the plate is rotated and performed the second cut 30 degrees to the first in the form of an X (X-cut). Incisions are cleaned with a brush or with adhesive tape, after that, the adhesion value is visually evaluated according to the point system.
Bitumen And Mastic Insulation Adhesion Tester NOVOTEST CM-4219
Adhesion tester NOVOTEST CM-4219 is a device for measuring the adhesion value of bitumen pipe insulation and other insulating coatings which are based on bitumen. Adhesion tester NOVOTEST CM-4219 is a mechanical device which allows to determine the adhesion value of quality and quantity, by measuring the strength of sticking the bitumen insulation to the surface of the pipeline.
This dispositive allows user to take measurements during testing; planned inspections of steel structures and pipelines after their installation, and also after performing the repairs in order to identify defects during the application of the insulation, as well as for the subsequent monitoring of the quality of performed works. The device has been successfully used in the “field” and in the laboratory conditions.
Peel Adhesion Tester NOVOTEST AP-4219
Adhesion tester NOVOTEST AP-4219 is designed to measure the adhesive strength value of the coatings on different structures, as well as to determine the adhesion value of polymeric insulating tapes which are generally used for pipes insulation. Adhesion tester NOVOTEST AP-4219 is reliable and easy in operation.
The design of instrument allows user to operate at low temperatures or conditions of high humidity and dust.
