T-Bend Tester is designed to evaluate the flexibility and adhesion of an organic coating on a metallic substrate by observing the cracking or loss of adhesion when a coated test panel is bent.
This method can be used to confirm whether paints, varnishes or related products meet a given test requirement in a pass/fail test, or to determine the minimum bending diameter at which cracking does not occur.
This instrument complies with the ISO17132.

Scope of application:
Film flexibility is a measure of paint one of the important indicators of the new varieties of paint formulations of screening applications have great reference value.
The Bending Tester is a new model for testing the flexibility of coatings.
It is suitable for testing the T-Bending Tester of coated steel sheets and strips, as well as T-Bending Test instrument.

The main structure:
Floor and left and right side panels.
Gear and crank lift mechanism.
Triangle bent Yaping fast.
Square rotation split pieces.
Guard and handle and other components.
Experimental results to determine:
After bending, each panel is examined :
- with a magnifying glass for cracking of the coating
- and by a tape pull-off test for loss of adhesion of the coating.
The minimum diameter to which the test panel can be bent without cracking or loss of adhesion,i.e.when failures on longer occur, is taken as the T-bendrating.
Use Scotch tape (≥0.25N / mm) against the curved surface of the test, flatten the tape with your fingers, and then peel it off in the direction perpendicular to the coating surface to check if the coating is peeled off or peeled off Determine the flexibility of the coating.
Caution:
1. When the specimen is bent at IT, there should not be any obvious gap at the bending surface.
2. Coating damage within 10mm from the edge is not taken into account.
3. In order to facilitate the transport, the test machine out of the company, the two handles are not installed on the host.
After the user devanning, with the wrench will be installed on the host two handles the appropriate position, and be careful to tighten.
It conforms with DIN EN ISO 17132, ASTM D 4145, EN-13523-7 (Paints and varnishes – T-bend test).
Standards :
ISO 17132:2007 describes a method of evaluating the flexibility and adhesion of an organic coating on a metallic substrate by observing the cracking or loss of adhesion when a coated test panel is bent.
The method can be used to confirm whether paints, varnishes or related products meet a given test requirement in a pass/fail test, or to determine the minimum bending diameter at which cracking does not occur.

Working principle:
Through the rotation of the left handle, the square bending buckle bending pieces parallel to the shape of <45 ° angle: turn the right handle, driven by the crank lift mechanism so that the triangle bending fast rise or fall, the specimen clamping or pressure Flat, form a T-bend.
