most commonly used methods of paint testing

1. Bubble viscometers can determine viscosity of varnishes and resins in a short period of time. Flow cups and Brookfield viscometers are also to measure viscosity.
2. Weight per gallon cups are essential for quality control. When these are not used, paint composition errors are likely, which can result in varying density readings.
3. Testing paint dispersion is an important part of testing a coating in the wet form.
4. Paint test charts or byko-charts allow you to prepare a sample for testing.
5. The use of a light booth can help to test paint colors for metamerism and other light influenced appearances. Through the use of light, color assessment is much more accurate, and product rejections are reduced.
6. A spectrophotometer can be used to calculate color and gloss values of the dry paint to ensure your batch is within the set tolerances.
7. The gloss value of the paint and the paint thickness can be objectively evaluated with the micro-TRI-gloss with thickness.
8. For a paint coating technologist, a paint and coating testing manual is essential. This guide will provide information on standards, test procedures, regulations and much more
