CAUSE
|
REMEDY |
| A |
Presence of foreign vapors/fumes. |
Investigate the nature of vapors which might be
present. It will then be necessary to shield off the vapors from contact
with the finish. |
|
B |
Water-borne coatings will rust steel parts or
oxidize aluminum in application equipment and can contaminate coatings. |
Change to stainless or plastic parts. |
| C |
Improper drum liner. |
Make certain correct liner is being used. |
|
D |
Using old nitrocellulose products. |
Nitrocellulose finishes tend to amber in color as
they age, even in a closed container. Always use as fresh material as
possible. |
| E |
Tannin bleed when using water base coatings. |
Use undercoater as first coat to stop tannin
bleed. |
