Overview
YINGXU 100 * 150 test cardboard is a China black and white Opacity Chart with a size of 100 * 150mm (actual size 98 * 152mm), no Laminating on the surface, and a black and white half style design. This product is specially used to evaluate the hiding power performance of samples in experimental film testing such as Coating and inks.
Features
1. Black and white half style design is convenient for hiding power comparison evaluation
2. Laminating the surface to ensure test accuracy
3. Standard size 100 * 150mm (actual 98 * 152mm) meets the experimental requirements
4. Encasement specification 100 sheets/pack, to meet the needs of batch use
Principle
The test cardboard is designed with black and white half color blocks, and the covering effect of the coating on the black area is observed after Spreader Coating or inks to evaluate the covering performance of the sample. When the coating completely covers the black area, it indicates that the sample has good hiding power.
Applications
Coating test, inks test, film detection, hiding power performance evaluation
Steps
1. Prepare test jams and samples to be tested
2. Spreader samples evenly at the black and white junction of the cardboard
3. Observe the effect of coating on the black area
4. Evaluate the sample hiding power performance according to the degree of hiding
Notice
• Make sure the surface of the cardboard is clean and free of contamination before testing
• Spreader should ensure uniform coating
Avoid use and storage in humid environments
• It should be properly stored after use to avoid folding or damage
