If maximum recoat interval is exceeded, roughen the film surface to ensure the adhesion between layers.
如超过最大重涂间隔，须磨粗表面，以确保漆膜间的附着力。
No maximum recoat interval for adhesion, but dictated by gradual breakdown and damage during exposure and fabrication.
对于附着力来说，无最大重涂间隔，但具体情况要视漆膜暴露于污染环境及加工中受损坏的程度而定。
If maximum recoat is exceed, roughening of the surface is necessary to ensure intercoat adhesion.
如超过最大重涂间隔，须磨粗表面，以确保漆膜间的附着力。
If maximum recoat is exceed, roughening of the surface is necessary to ensure intercoat adhesion.
