This technical specification outlines a standardized procedure for preparing test panels using a drawdown bar equipped with a magnetic base. The method is designed to ensure uniform film thickness and consistent application quality across various coating materials. It defines the required dimensions and specifications for the magnetic drawdown apparatus, including the gap setting mechanism and base plate materials. The procedure details the step-by-step process for applying liquid coatings onto rigid substrates under controlled conditions. Key aspects include surface preparation of the substrate, the precise angle and speed of the drawdown instrument, and post-application handling requirements. This approach facilitates reliable comparison of coating properties such as opacity, texture, and drying characteristics. By adhering to these defined parameters, laboratories and industrial facilities can achieve reproducible test results for quality control and research purposes. The standard serves as a reference for manufacturers and testing agencies to evaluate coating performance without ambiguity regarding the application technique.
