Overview
The PUSHEN PS 2653 HGB cross-cut board is a tool for rapid measurement of the adhesion of many different types of coatings. It is convenient and simple to determine the adhesion fastness of coatings to substrates with a film thickness of less than 250 microns on the surface of wooden furniture and other wooden parts or the adhesion of substrates to each other.
Features
1. Convenient and simple, easy to operate.
2. Suitable for a variety of different types of coatings.
3. Tooth spacing is available in a variety of specifications (1mm, 1.5mm, 2mm, 3mm) to meet different testing requirements.
4. Made of stainless steel, strong and durable.
5. The scratch length is 35mm, the number of teeth is 11, and the design meets the test standards.
Principle
The cross-cut plate draws a regular grid of scratches on the coating surface through its specific spaced (e.g. 1mm, 1.5mm, 2mm, 3mm) cutter teeth. The adhesion of the paint film to the substrate or the bond fastness between the substrates is evaluated by observing the flaking of the coating in the scratch area. Its design is suitable for coatings with film thickness in the range of 0 to 250 microns.
Applications
Wooden furniture, other wooden parts surface coating adhesion test
Steps
1. Select the appropriate cross-cutting plate with tooth spacing according to the Coating thickness (0~ 250μm) to be tested.
2. Place the cross-cut plate perpendicular to the coating surface.
3. Apply uniform pressure to scratch the mesh on the coating.
4. Use tape to stick to the scratched area and tear it off quickly.
5. Observe the flaking of the grid area coating and evaluate the adhesion grade against the standard.
Notice
• Coating thickness (0~ 250μm) to select the appropriate tooth spacing.
• Apply uniform and appropriate pressure during operation to ensure clear and consistent scratches.
• Ensure that the coating surface is clean, drying and flat before testing.
• This instrument is a precision tool, please clean and keep it properly after use to avoid damage to the knife teeth.
• When evaluating results, please strictly refer to relevant standards such as GB/T 9286 for judgment.
