Product description:

Nanotech industry products Cross-cut testing device is a professional Cross cut testing device for the precise and reliable determination of the adhesion of coatings, especially painted surfaces and similar samples using a precision-made cross-cut knife.

The testing method of cross-section is based on the test standards ISO 2409, ISO 16276-2 and ASTM D3359 carried out. The adhesion of surface coatings is determined using a Cross cut noted. The Cross cut knife features various precision-engineered 6-edge and 11-edge blades with a spacing of 1mm, 2mm and 3mm. The choice of Cross-cut blades is selected according to the layer thickness of the surface coating and based on the recommendations of the test standard.

• For coating thicknesses of 0µm - 60µm, a cross-cut blade with a grid spacing of 1mm is recommended.
• For coating thicknesses of 61µm - 120µm, a cross-cut blade with a grid spacing of 2mm is recommended.
• For coating thicknesses of 121µm - 250µm, a cross-cut blade with a grid spacing of 3mm is recommended.

The Cross-cut test is done using one cross-cut knife carried out, this involves scratching cuts at right angles into the surface coating so that a square pattern is created. After carefully removing dust and loose particles, this square pattern is evaluated with the naked eye and using a magnifying glass. The assessment takes place in 6 levels. These levels are called Cross-section characteristics Here, for example, “GT 0” denotes a very good adhesion property.

This professional Cross-cut testing device offers the latest technology and design combined with a comfortable wooden handle, a variety of precision-made cross-hatch blades, a high-quality magnifying glass, a brush, a roll of 3M tape, a comfortable carrying case, made of high-quality materials, high accuracy and high precision, an ergonomic design and much more.

This professional cross-cut tester is manufactured to internationally recognized testing standards including:  

• DIN EN ISO 2409 (Coating materials - cross-cut test (ISO 2409:2020); German version EN ISO 2409:2020)
• ISO 16276-2 (Corrosion protection of steel structures by coating systems - Assessment of the adhesion/cohesion (adhesive strength) of a coating and criteria for its acceptance - Part 2: Cross-cut and cross-cut test (ISO 16276-2:2007); German version EN ISO 16276-2 :2007)
• ASTM D 3359 (Standard Test Methods for Rating Adhesion by Tape Test)
