What is Coating Ratio?
Abstract:
本文讲述了涂料对比率的定义和测量方法。涂料对比率用于评估涂料的遮盖能力，遮盖能力越强，涂层厚度可以越薄，从而覆盖更大面积。测量涂料对比率时，将涂料均匀涂布在遮盖力纸上，待干燥后，通过观察纸上的黑白形状来确定底材的遮盖程度。涂料对比率是涂料检测中的重要标准。
The paint contrast ratio is mainly to measure the hiding ability of the paint. The better the hiding ability, the less thick the coating thickness is, so the painting area will be larger.
To measure the paint contrast ratio, the paint is evenly scraped on the hiding power paper by a wire Bar Coater. After drying, the degree of substrate coverage is measured by the black and white shape on the hiding power paper.
Paint contrast ratio is a very important measurement standard in paint testing standards.
