PUSHEN PS 2930/1 small black and white paper is a series of ZGL hiding power measuring cardboard products, made of high-quality non-fluorescent paper and does not contain Fluorescent Whitening Agent. The exact area of the test piece is 0.1 square meters, which is suitable for brushing at a specific spreading rate and has become the market standard product in the coating industry.
Features
Black part reflectance < 1, white part reflectance at 80 +/- 2
2. Laminating cardboard has good wettability to paint materials, will not check or cissing
3. The exact area of the spreading rate test piece is 0.1 square meters (about 1 square foot)
4. Made of high-quality non-fluorescent paper, without Fluorescent Whitening Agent that affects Color Testing
Principle
The black and white contrast area of the test coating covering performance, black part of the low reflectance and white part of the high reflectance formed a clear contrast, easy to evaluate the coating covering effect.

Paints, paints, inks hiding power testing, paint rapid proofing
Steps
1. Prepare PS 2930/1 test jam
2. On the cardboard brushing paint to be tested
3. Observe the covering effect of paint in black and white areas
4. Evaluate hiding power performance
Notice
• Laminating type with good wettability
• Pay attention to moisture-proof and pressure-proof when storing
• Check whether the surface of the cardboard is intact before use
