The toolkit is designed for the ASTM D3359 (Method A) Standard Test Method for Measuring Adhesion by Tape Test for coatings that exceed 5 mils. The Gardco X-Cut template tool and cutter performs the X-cut test, also called the cross-hatch test, by making a series of closely spaced cuts...
The results demonstrated that the tape peel test is a sensitive method for measuring coating adhesion on different materials found on PCB assemblies. Coating adhesion was found not to be effected by a wide range flux residues, but components and some resists presented a far greater coating ...
Formability and adhesion testing of factory applied zinc-rich primer/chromate complex coatings on steel is described in ASTM 4146. In this test, a coated specimen is biaxially stretched a given distance in an appropriate machine, adhesive tape is applied to the deformed area (dome) and then pull...
Handheld coating thickness and inspection instruments: Adhesion, Dew Point, Surface Profile, Salt Contamination, Wall Thickness, Porosity, Shore Hardness and more
If there is a little corner here or there that has been pulled off it would likely still be ok and would pass the test. Check out Dave showing you how to perform the cross hatch adhesion test in this short video.To determine performance, there is an ASTM rating scale to make the ...
14.7. Surface damage by crosshatch cutter for evaluating the coating adhesion on plastic substrate. Coatings with excellent adhesion can be further evaluated at the intensified test level. This evaluation involves the crosshatch test, tape test and additionally the boiling test. The boiling test simulat...
ASTM D3359, Standard Test Method; ‘Measuring Adhesion by Tape Test’. • ASTM D4541, Standard Test Method; ‘Pull-Off Strength of Coatings Using Portable Adhesion Testers’. • CSA 245.21, ‘External Polyethylene Coating for Pipe’, Type A1 and A2. Type 2 coating standards specify the ...
*Make sure the primed surface remains free from contaminants before you apply the tape. *THIS IS NOT A GLUE AND CANNOT BE USED SOLELY AS A GLUE. THE ADHESION PROMOTER IS FOR BETTER ADHESION OF YOUR TAPE. YOU NEED TO APPLY IT ON A TAPE OR ANYTHING ADHESIVE. Application ---...
2. Adhesion Test The coating adhesion test, also known as the Tape Adhesion test, was developed by American Hardboard Association, Palatine, Ill. to determine the strength of the adhesion of the coating to the underlying surface of a test substrate. A standardized pressure sensitive adhesion tape...
20. Water immersion, gloss, adhesion tape test and gouge hardness results indicate the 75 and 100° C. cured coatings performed in a similar manner. The 100° C. cured coating exhibited slightly better MEK resistance, but was slightly less scratch resistant than coatings cured to 75° C. ...
