Paint Auxiliaries Testing

Paint auxiliaries are substances added to the paint that can control or enhance the performance of the paint. Generally speaking, adding a small amount of auxiliaries can improve the performance of the paint, so the performance of the paint is closely related to the quality of the auxiliaries.

Paint auxiliaries testing is mainly to detect the performance of auxiliaries in paint products to evaluate the quality and utility of auxiliaries. It is of great significance for the optimization of the production process, the improvement of product quality and the research and development of environmentally friendly auxiliaries in the paint industry.

STEMart provides comprehensive paint auxiliaries testing services to ensure the quality and performance of paint auxiliaries, improve the production efficiency of the paint industry.

Test Samples

Drier, toughening agent, emulsifier, thickening agent, pigment dispersant, defoamer, leveling agent, anti-crusting agent, matting agent, light stabilizer, anti-mold agent, antistatic agent, etc.
