Overview
The American Leneta WB sealed Opacity Chart is a pure white Opacity Chart with a surface sealed, Dimensions of 194x286mm, ASTM compliant, mainly used in the Coating inks industry.
Features
1. Pure White Opacity Chart, surface sealed
2. Meet ASTM standards
3. Different Dimensions Available
4. Encasement specification is 250 sheets/box
5.The weight is 4.54kg
6. Applicable to the Coating inks industry
7. Can be used for hiding power test and levelling sag test
Principle
The Opacity Chart is used to test the hiding power of paints and other coatings by providing a pure white surface. The hiding power calculation formula is: hiding ratio (%) = Y black/Y white * 100%, 100% means complete covering. During the test, the Coating uniform Spreader is placed on the paper, and after drying, the hiding power value is measured by the instrument.
Applications
Marine, Aerospace, Mobile phones & digital products, Biology, Coating inks
Steps
1. Spreader paints and other Coatings evenly on the paints Opacity Chart according to the film steps
2. After the film is fully dried by air, use the instrument for objective evaluation
3. The hiding power value can be measured within 1 second and automatically displayed
Notice
• Use the correct lame plating method to ensure that the film thickness is appropriate, flat and uniform
• The space of the spray booth should be suitable, Illumination conditions should be good, and special attention should be paid to the lame plating mass in the inaccessible area when lame plating
• Mix the paints effectively
• Prohibit excessive polishing of the paint film, pay special attention to the corner area
• Applicator rods and other auxiliary tools need to be used during testing
