涂層的結合強度，又稱為涂層的附著力，是指涂層與基體結合力的大小，即單位面積的涂層從基體或中間涂層上剝落下來所需的力。附著力不好的產品，容易與物面剝離而失去其防護與裝飾效果。因此，涂層與基體的結合強度是涂層性能的一個重要指標之一。通過這個項目的檢查，可以判斷涂料配方是否合適。

涂層附著力檢測相關技術標準

標準名稱：色漆和清漆拉開法附著力試驗
標準編號：GB5210-2006-T
實施日期：2007年2月1日
標準概述：本規范規定了色漆、清漆或相關產品的單層或多涂層體系上進行拉開法附著力試驗而測定附著力的試驗方法。本規范對于比較不同涂層的附著力大小是有效的。對附著力有明顯差別的一系列已涂漆試板提供相對評定等級則更為有效。本規范適用于多種底材，不同類型的底材采用不同的步驟。易變形底材，如薄金屬、塑料和木材；堅硬底材，如厚的混凝土板和金屬板。對于特定的場合，涂層可以直接制備在試柱表面上。


標準名稱：Standard Specification for Friction Tape；ISO 4624_2002 Paints and varnishes — Pull-off test for adhesion
標準編號：ASTM D4514 - 12
標準概述：This standard is issued under the ?xed 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.


標準名稱：Paints and varnishes — Pull-off test for adhesion
標準編號：ISO 4624-2002
標準概述：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.
