Paint Test Strip

Paint test strips utilize a color-change reaction when the coating comes into contact with the strip to detect the content of volatile substances in the paint. They are used for on-site rapid assessment of paint dryness and solvent residue, commonly employed in quality monitoring for painting processes such as furniture manufacturing and automotive repair.
Selection
When selecting, consider the compatibility of the test paper's sensitivity with the type of paint being tested, observe the clarity of the color comparison card, confirm the validity period and storage conditions of the test paper, and choose the corresponding specification based on the humidity range of the on-site testing environment.
