玻璃鱗片膠泥作為防腐層zui簡單的方法，就是使流體介質與基體隔絕，而膠泥涂料通常存在孔隙，流體介質（水、酸、堿等）小分子的直徑一般比涂層的孔隙要小，加上這些與涂層接觸的介質都是直線地通過，而涂層又不可能涂得很厚（否則要產生裂紋），一般的膠泥涂料即使可以較好地耐其所接觸的介質腐蝕，但它抵擋不住介質向基體的擴散滲透。所以，普通的防腐涂料一般只能作為大氣防腐而不能起到襯里的作用，尤其在液相介質和溫度較高的場合。玻璃鱗片膠泥的加入使涂料發生了二方面的變化，一是可以加工成很厚而不要擔心會發生裂紋，這是因為玻璃鱗片把涂層分割成許多小的空間而大大地降低了涂層的收縮應力和膨脹系數；二是由于玻璃鱗片膠泥的多層平行與基體排列，使介質擴散滲透的路線變得彎彎曲曲，增大了介質滲透擴散至基體的阻力。用于涂料中的玻璃鱗片膠泥具有魚鱗效應：成千上萬的鱗片交錯排列，形成涂層內復雜曲折的滲透擴散途徑，使得腐蝕介質的擴散路線變得相當曲折，很難達到基材。

Method of glass flake coating as the most simple, is to make the fluid medium and matrix isolation, and clay paint are pore fluid medium (water, acid, alkali and other small molecules) are generally higher than the coating pore diameter is smaller, and the contact with the coating medium are straight through, and coating it can not be painted very thick (or cracks), clay coatings generally even better corrosive medium of the contact, but it could not withstand the permeability to the matrix diffusion. Therefore, generally only the ordinary anticorrosive coating for atmospheric corrosion can not play the role of the liner, especially in liquid medium and high temperature applications. Adding glass flake clay to paint has changed in two aspects, one is can be processed into very thick and don't worry about the occurrence of crack, this is because the glass flake coating is divided into many small Space and greatly reduce the coating of shrinkage stress and expansion coefficient; the second is due to the fact that the glass flake clay layers of parallel and matrix arrangement, and the medium penetration and diffusion of route to become crooked, increasing the medium permeability resistance of diffusion to the substrate. For coating glass scale clay has scale effect: scales of tens of thousands of staggered to form coating in complex and tortuous diffusion pathway, making of corrosive medium diffusion route become quite twists and turns, is difficult to reach the substrate.
