Penetration covering power card

Penetration and Hiding Power Cardboard is a testing material used to evaluate the hiding ability and permeability of coatings or inks. The principle involves applying the sample onto a black-and-white grid cardboard and observing the color coverage and the extent of penetration on the reverse side to assess performance. Its function lies in quickly comparing the hiding effects and anti-penetration capabilities of different products. It is applied in quality control during the production processes of coatings and inks, helping to adjust formulations to meet practical requirements.
Selection
When selecting permeable hiding power test cards, consider the basis weight and surface smoothness of the card to ensure compatibility with the test material. Check whether the black-and-white grid contrast on the card is clear for accurate evaluation of hiding power. Confirm that the liquid absorption of the card is moderate to avoid excessive penetration affecting the results. Refer to industry standards or supplier specifications to match the actual application scenarios. Perform sample verification before testing to ensure stable and reliable card performance.
