Overview
PUSHEN PS 2930/4 Checkerboard is one of the ZGL hiding power assay cardboard series, made of high-mass non-fluorescent paper, does not contain Fluorescent Whitening Agent, and has become the market standard product in the coatings industry. The test piece has an exact area of 0.1 square meters and is suitable for brushing at a specific spreading rate.
Features
Black part reflectance < 1, white part reflectance at 80 +/- 2;
2. Laminating cardboard has a smooth surface and stronger anti-Curling ability when stoving;
3. Laminating cardboard is good for the wettability of paint materials, and will not check or cissing;
4. Made of non-fluorescent paper, does not contain Fluorescent Whitening Agent, does not affect Color test.
Principle
Checkerboard paper provides a contrast substrate through its black and white pattern to evaluate the hiding power of paints, paints or inks. After Spreader, the covering performance of the paint is judged by observing the degree of covering of the pattern, ensuring accurate and reliable testing.
Applications
Paints, paints, inks hiding power testing, Miscellaneous paint rapid proofing
Steps
1. Prepare PS 2930/4 Checkerboard paper test pieces;
2. Spreader coating evenly on the test piece;
3. Observe the covering of the black and white pattern.
4. Evaluate the hiding power performance of the paint.
Notice
Make sure the surface of the test piece is clean to avoid contamination affecting the results.
- Spreader should be uniform to avoid thickness inconsistency;
- Laminating cardboard in the stoving attention to anti-Curling, avoid deformation;
- Keep drying when storing to prevent moisture damage to the paper.
