Overview
PUSHEN PS 2930/7 small white paper is an all-white test piece in the ZGL hiding power measurement cardboard series. It is made of high-mass non-fluorescent paper and does not contain Fluorescent Whitening Agent. The exact Spreader test area is 0.1 square meters. It is suitable for brushing at a specific spreading rate.
Features
1. The reflectance of the white part is 80 +/- 2 to ensure the accuracy of the Color test.
2. Laminating design, good wettability to paint, no checking or cissing.
3. Made of non-fluorescent paper, does not contain Fluorescent Whitening Agents that affect Color Testing.
4. Spreader test area is accurate to 0.1 square meters, suitable for standard spreading rate test.

After Spreader, the covering performance of coatings can be quickly judged by observing the covering effect of coatings on white backgrounds.
Applications
Paints, paints, inks hiding power testing, paint rapid proofing
Steps
1. Prepare PS 2930/7 small white paper test piece.
2. Evenly brushing the paint to be tested on the surface of the test piece.
3. Observe the covering effect of the coating on the white background.
