Overall dimensions are 194 x 289 mm (7-5/8 x 11-3/8 inches).
Features
1. Black and white contrast design, easy to observe the film effect.
2. Laminating and non-laminating alternating areas are provided to test the performance of the paint on different surfaces.
3. Use Penopac cardboard material to ensure test Stability and conformity.
4. Standard size design for easy operation and comparison.
5. Encasement specification is 250 sheets/box to meet the needs of batch testing.
Principle
The Paint Chart provides a standardized contrast substrate for Spreader testing of liquid materials such as coatings and inks through its alternating black and white areas on the surface and Laminating and non-Laminating areas. Users can visually evaluate the differences in their hiding power, Color, Glossiness, leveling and other performance under different surface states by Spreader of the material to be tested on the cardboard.
Applications
Coating R & D and Quality control, inks performance testing, gluing agent testing, laboratory standardization evaluation
Standards
ASTM D344、ASTM D823、ISO 1514
Steps
1. Prepare samples of paint or inks to be tested.
2. Remove a Form 19BR test cardboard and place it on a flat work surface.
3. Spreader the sample evenly on the test area of the cardboard using the specified coating applicator (e.g. drawdown blade, Mayer Rods, etc.).
4. Make the film drying under standard conditions (e.g. specified temperature, Humidity).
5. Observe and evaluate the performance of the film in white, black, Laminating and non-Laminating areas, and record hiding power, Color, Gloss and other data.
Notice
• Before testing, make sure that the surface of the test cardboard is clean and free from damage.
• Spreader and drying should be performed in a standard Humidity environment to ensure comparability of test results.
• After use, the used test cardboard should be properly disposed of in accordance with laboratory regulations.
• This product is a one-time test consumable, please do not use it for repeability.
• Encasement in good condition when storing, in a cool drying place, away from direct sunlight.
