ASTM D4941-06 (2021) Standard Preparative Method for Artist Slurry Coatings provides standardized procedures for the preparation of artist slurry coatings, particularly for standardized testing of slurry sink. The standard details sampling, Spreader, drying, and testing procedures for artist slurry coatings to ensure repeatability and accuracy in the determination of sink in different batches of artist slurry coatings. Through the implementation of this standard, artists can better understand and control the consistency and flowability of coatings, and ensure the mass stability of coatings during the creative process. The standard is an important reference for artists, manufacturers and quality control departments to ensure Coatings performance.
