Overview
NWF White Paint Chart is a laboratory-specific film Opacity Chart of the LENETA brand. The product is pure white, with Dimensions of 75 x 184mm, Film thickness of 0.35mm, and a standard Encasement of 1000 sheets per box.
Features
1. Inorganic coating components (such as Calcium Carbonate, Kaolin and Titanium Dioxide) account for more than 92% of the paper coating materials.
2. Stock pressing is mainly starch and contains synthetic organic polymer gluing agent.
3. The product has a high reflectance, with a minimum Y value of 80%.
4. The paper Basis Weight (Grammage) is 308 g/m ², and the Film thickness is uniform.
5. Standard Encasement specification, 1000 sheets per box, easy to use and manage in batches in the laboratory.
Principle
The Paint Chart provides a standard test substrate for Spreaders of liquid materials such as coatings and paints through its pure white, high reflectance (Y ≥ 80%) and stable surface. After the Spreader, the hiding power, Color display and other performance of the test material are evaluated by observing or measuring the covering effect of the coating on the cardboard.
Applications
Lab film hiding power test
