Nichiban Cellulose Tape CT-18 / LP-18 for Coating Test


Description:

Manufacturers of automobiles, toys and home electronics conduct coating test to check the coating adhesion and adherability of the product.
There are several different tests to measure the resistance of paints and coatings from base material. This time we will introduce one of them called “Cross-cut Test”.
The cross-cut test method uses a grid pattern perpendicular to the surface of the coating to determine the degree of separation from the base material after cutting.
This method can quickly check suitability and the degree of separetion of each coating layer from multiple coatings.
The test method is as follows:
(1)Making cut lines as grid
(2)Attaching the tape to cut lines
(3)Peeling off the tape and observing the tape and cross-cut area
For this test, many Japanese manufacturers use Nichiban's self adhesive cellulose tape CT-18 and LP-18. Because Nichiban’s cellulose tape CT-18 and LP-18 conforms to standards for “pressure sensitive adhesive tapes” defined in JIS Z 1522.
