High-mass Paint Chart, widely used, can be used in almost any application and Coating material. And strict quality control is implemented in the production process to ensure that it has the best Color and Gloss conformity in the industry. The test cardboard is easy to use and can be tested for many hours, such as hiding power, spreading rate, permeability and levelling sag. Widely used in construction, industry, wood surface preparation and automotive industries.
The choice of Opacity Chart is related to the Coating process. Different paints require test cardboard to have different solvent resistance, stronger or weaker. Different types of Resin use different solvents. The polarity of the solvent determines whether its organic components can be activated more or less.
Choose different test cardboard according to different applications
Opacity Chart: Instrumental measurement of hiding power
Permeable cardboard: Used to assess the conformity of Gloss and Color of surfaces with voids
Visual assessment of hiding power:
- matching/spreading rate cardboard
- Checkerboard/spreading rate
Cardboard for informal painting
Dedicated test cardboard for sag and levelling tests.
