Overview
The TQC sheen SP1695 adjustable cross-cut adhesion meter is an instrument imported from the Netherlands for the determination of paint film adhesion by cross-cut method. It evaluates the adhesion degree of the film to the substrate by evenly drawing a grid of certain Dimensions and evaluating the integrity of the film in the grid, expressed in'grade '. The instrument is not only suitable for laboratories, but also can be used in construction sites under various conditions, and is widely used in the determination of organic coating cross-cut adhesion.
Features
1. Adjustable accuracy to achieve precise cutting depth and accurately test adhesion
2. According to the standard for different film thickness and substrate tool size, suitable for a variety of adhesion testing
3. Composed of lightweight, comfortable handlebars and tough knives, the specifications are easy and convenient to carry
4. Package includes brush, magnifying glass and tape
5. The blade holder maintains a fixed distance between the paint film surface and the two auxiliary wheels to ensure Repeatability
Principle
Cross-cut Tester uses the principle of cross-cut adhesion test to evenly draw a grid of certain Dimensions through a tool with single or multi-piece cutting. The degree of film adhesion to the substrate is assessed by evaluating the integrity of the film in the grid, expressed as'level '. The cutting depth can be precisely adjusted to ensure the test Repeatability.
Applications
Organic coatings cross-cut adhesion determination, laboratory testing, construction site testing
Standards
ASTM D3359-2009
Steps
1. Adjust the instrument accuracy and cutting depth according to the test needs
2. Use cross-cut Tester to evenly draw squares on the surface of the paint film
3. Use the matching brush to clean the cutting area
4. Use tape to paste and tear off, evaluate film adhesion
5. Observe the integrity of the film in the grid through a small magnifying glass
6. Determine the adhesion grade according to the evaluation criteria
Notice
• Coating's flexibility and interference layer may affect test results
• Select the appropriate tool size according to specific test requirements
• Cutting Depth Needs to Be Adjusted to Ensure Test Repeatability
• Accessory products such as magnifying glass, brushes and tape need to be purchased separately
• The material of the instrument is vacuum hardened stainless steel, aluminum and rubber, which should be properly kept
