ASTM D3359 Cross Hatch Adhesion Test Tape,W=1",L=160 ft,Grey

The GLTL ASTM D3359 Cross Hatch Adhesion Test Tape has become a dependable staple in my lab for quality control and coatings inspection. For anyone involved in paint, coatings, or surface treatment testing, this tape delivers consistent, reproducible results every time. It’s exactly what you want when accuracy matters.Right out of the roll, the tape feels high-quality—rigid enough to be applied smoothly without curling or stretching, but still easy to tear or cut cleanly. The adhesive is strong but controlled, meaning it bonds well to a variety of surfaces without leaving any frustrating residue behind.In actual use, this tape performs exactly as required under the ASTM D3359 standard. I’ve tested it on everything from powder-coated metals to plastic panels and even some oddball samples like treated glass. It peels off cleanly and gives a very clear indication of coating adhesion without damaging substrates.The grey color is also a subtle but smart feature—it makes it easier to visually check for separation without interfering with the sample surface's own coloring. This helps when photographing results or logging inspections for recordkeeping. A small detail, but it adds to the overall user experience.The roll length is generous at 160 feet, and even with regular daily use, it lasts a long time. I’ve used some cheaper tapes in the past that were inconsistent across batches—either too weak or overly tacky. That hasn’t been the case with this brand. Every test has performed to spec, with no signs of adhesive degradation or quality drift.It comes off the roll smoothly and evenly, which really helps when you're doing multiple tests in a row. You don’t lose time dealing with tape that shreds, splits, or sticks to itself. The consistency makes a big difference in productivity and minimizes waste.Overall, this is a top-tier product for any professional who needs reliable cross hatch adhesion testing. It meets the standard, applies cleanly, and delivers consistent results every time. If you’re tired of fiddling with unreliable tape for critical coatings work, this one’s worth every penny.

This is not your normal duct tape, they are used by professional testing and reporting different paint jobs: what kind of paint, top layer or second layer, how's the paint applied, the method of curing, etc. My research indicates that this is not the best but acceptable testing tape (the top products cost a lot more). But a detailed instruction on how to use, to read and to report different paint jobs is included. Good quality adhesion test tape that can do the test reasonably well.

I bought a roll and had it tested for strength. It did not meet the ASTM standard so we did not use it
