im体育APP’s water immersion testing services evaluate a coating’s resistance to in-service immersion conditions. This helps determine the coatings suitability for corrosion protection during its service life. 

 

Immersion testing method

Immersion tests form the basis of many different standards, as well as being standalone tests in their own right.

The basic test involves a coated test sample being fully or partially immersed in water, at ambient conditions or at elevated temperatures and pressures. The coated samples are then assessed for any signs of degradation, 包括起泡, 破解, 还有附着力损失.
