KTA X-Cut Guide Package
One of the most frequently performed physical tests conducted on in-place coating systems is tape/knife adhesion. Performing this test in strict conformance to the ASTM standard is critical for obtaining accurate adhesion ratings. ASTM D3359, “Measuring Adhesion By Tape Test” describes two methods: Method A (X-cut) is used for coatings in excess of 5 mils; and method B (Cross-cut) is used for coatings up to 5 mils thick. If your coating system is less than 5 mils thick, then Click Here.
Method A requires making two cuts in the film each about 1.5 inches long that intersect near their middle with a smaller angle (between 30 and 45°) using a straightedge, cutting through the coating to the substrate in one steady motion. Using a straight edge or ruler to guide the knife blade can result in an injury. Replace the straightedge and achieve the correct angle at the intersection of the X using the KTA X-Cut Guide/Template.
The KTA X-Cut Guide Kit contains everything you need to perform tape adhesion testing on coating films in excess of 5 mils. The highlight of this kit is the X-Cut Guide/Template. This precision machined, stainless steel guide/template helps ensure that each leg of the incision will be 1.5″ in length while the interior angle is maintained between 30° and 45° per ASTM D3359 requirements. The kit comes complete with an X-Cut Guide, 5x Magnifier, Adhesion Test Tape, Utility Knife and 3 replacement blades, a copy of the ASTM D3359 Standard all in a LIFETIME Warranty Pelican 1400 carrying case.
Replacement items including tape, utility knife and knife blades, test method, LIFETIME Warranty Pelican carrying case and Guide pouch are all available for purchase. Conforms to ASTM D3359. Made in the USA.
