Not in This Discussion:

Coating and Linings

In the realistic world:

Surface Preparation Issues (+50% failures easily)

Ambient Conditions/Application Issues (mix ratios)

Wrong specification for environment

处理不佳的表面和错误应用是导致失败的重要因素

一定要参考并且执行准则要求

质量检测是必要的！

• Chemicals and Concentration

• Presence of Trace Chemicals

• Ambient Conditions

• Upset Conditions

• Size of Solid Presents

• Temperature Cycling
