Overview
CHBLADE6X2 is a special blade for cross-cut Adhesion Tester under the Defelsko brand. This blade is designed for coating adhesion testing according to ISO 2409 and is one of the tool accessories required for cross-cut testing. It is made of hardened steel and has 4 cutting edges for extended test life.
Features
1. Designed for cross-cut Adhesion Tester, it is an essential part of the test suite.
2. Made of hardened steel, strong and durable.
3. With four usable cutting edges, it can be tested for longer periods of time and is easy to replace.
4. The number of teeth is 6, and the tooth spacing is 2mm, meeting the requirements of ISO 2409 standard.
Principle
The blade is the core cutting component of the cross-cut Adhesion Tester. During testing, the blade is driven by the instrument to cut a lattice pattern at a specific spacing on the coating surface to evaluate the coating's ability to resist separation from the substrate. The blade's 6-tooth design and 2mm spacing ensure that the cutting pattern meets the requirements of the ISO 2409 standard.
Applications
Coating adhesion test, coating performance evaluation, painting mass inspection
Steps
1. Install the CHBLADE6X2 blade correctly into the cutting head of the cross-cut Adhesion Tester.
2. According to the test requirements, adjust the instrument to ensure that the blade is perpendicular to the coating surface.
3. With uniform pressure and speed, push the instrument to cut on the coating surface to form a cross-cut pattern.
4. After cutting, use standard adhesive tape for adhesion and disbonding.
5. Evaluate the coating adhesion grade according to the rating chart specified in the standard.
6. When the cutting edge of the blade becomes dull, swirl/spin or replace the blade to continue using.
Notice
This blade is designed for cross-cut testing in accordance with ISO 2409 standards. Do not use it for testing to Miscellaneous standards such as ASTM D3359, which require 11-tooth blades.
When operating, ensure that the blade is firmly installed and the cutting pressure is uniform to obtain accurate test results.
* The blade is made of hardened steel, sharp and hard, use and storage should pay attention to safety, avoid scratches.
* When all cutting edges of the blade are abrasion, the new blade should be replaced in time to ensure the cutting mass.
* Please select the appropriate test parameters and rating method according to the test substrate and coating type.
