Method and Results
Method:
The next mechanical test performed was the
rigorous Crosshatch Adhesion Test, ASTM D3359. This test involves
cutting a grid of 100 squares into the coated panels. A pressure
sensitive tape is applied over the grid, and then rapidly
peeled away. The number of squares remaining on the panel
gives a relative percentage value of adhesion. Original specimens
of Wasser® Brand System (panel number 6), POR-15®
System (panel number 8), and Rust Bullet® (panel number
2), were evaluated for adhesion in accordance with the procedure
set forth in ASTM D3359. |
