CAUSE
|
REMEDY |
| A |
Sometimes strong solvents tend to react with the
preceding coat. Also air or gasses in film can be trapped as it dries
due to temperature, air movement or fast solvents being used. |
Be sure that the undercoats are thoroughly dry.
Use recommended primer. Use thinner with weakest solvent strength which
will still act as a steady diluent. If you are using heat lamps or oven
drying, be sure adequate flash off time is used before putting finished
part in oven. |
|
B |
Butyl cellosolve used as a retarder |
Butyl cellosolve is a heavy solvent. If too much
is used, it will sink to the bottom of the film. If top of film skins
over before complete film drying, then solvent pop can occur. |
