涂层的结合强度，又称为涂层的附着力，是指涂层与基体结合力的大小，即单位面积的涂层从基体或中间涂层上剥落下来所需的力。附着力不好的产品，容易与物面剥离而失去其防护与装饰效果。因此，涂层与基体的结合强度是涂层性能的一个重要指标之一。通过这个项目的检查，可以判断涂料配方是否合适。

涂层附着力检测相关技术标准

标准名称：色漆和清漆拉开法附着力试验
标准编号：GB5210-2006-T
实施日期：2007年2月1日
标准概述：本规范规定了色漆、清漆或相关产品的单层或多涂层体系上进行拉开法附着力试验而测定附着力的试验方法。本规范对于比较不同涂层的附着力大小是有效的。对附着力有明显差别的一系列已涂漆试板提供相对评定等级则更为有效。本规范适用于多种底材，不同类型的底材采用不同的步骤。易变形底材，如薄金属、塑料和木材；坚硬底材，如厚的混凝土板和金属板。对于特定的场合，涂层可以直接制备在试柱表面上。
标准名称：Standard Specification for Friction Tape；ISO 4624_2002 Paints and varnishes — Pull-off test for adhesion
标准编号：ASTM D4514 - 12
标准概述：This standard is issued under the fixed designation D4514; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
标准名称：Paints and varnishes — Pull-off test for adhesion
标准编号：ISO 4624-2002
标准概述：This International Standard is one of two standards which describe methods for assessing the adhesion of a single coating or a multi-coat system of paint, varnish or related product by measuring the minimum tensile stress necessary to detach or to rupture the coating in a direction perpendicular to the substrate.The test result is influenced not only by the mechanical properties of the system under test, but also by the nature and preparation of the substrate, the method of paint application, the drying conditions of the coating, the temperature, the humidity and other factors like the type of test instrument which has been used.The other International Standard is ISO 2409:1992, Paints and varnishes — Cross-cut test.
