Surface Cleanliness
|
˙ |
|
Surface contamination
from salts such as chlorides, sulphates and
nitrates have been shown to
|
˙ |
|
lead to blistering of organic coatings, particularly in
immersion conditions.
|
˙ |
|
It is not sufficient to measure the cleanliness of the substrate.
In a multi-layer coating process,
|
˙ |
|
it is necessary to monitor and record the cleanliness of each
layer prior to applying the next
|
˙ |
|
coating. When using amine cured epoxy
coatings, for example, in low ambient temperatures
|
˙ |
|
or in high humidity, a surface oiliness or exudate may cause inter-coating adhesion failure.
