Coating edge thickening

The phenomenon of thick film edges, also known as edge accumulation, occurs when the coating accumulates and thickens at the edges during the drying process. This is caused by the migration of liquid toward the edges due to surface tension. Its significance lies in reflecting the uniformity of coating application, and it is used to detect coating defects and control construction quality.
Selection
When selecting, focus on the accuracy range of the measuring tools and match them with the type of material being tested. Consider the impact of environmental temperature and humidity on measurements, and use non-contact instruments to avoid damaging the coating. Refer to industry standards to determine the allowable thickness deviation values.
