CAUSE
|
REMEDY |
| A |
Any material which will dry in the presence of
air at normal temperatures will tend to take on body. This occurs by
virtue of the evaporation of solvent (oxidation) which takes place. |
If body of the material has not proceeded to the
point where there is livering action, it is often possible to bring the
thickened particles back into solution. Addition of a stronger solvent
of the same general type or class should accomplish this task. |
|
B |
In the more advanced stages of oxidation, a
livering action often occurs. This is aggravated by the too-swift
addition of extra thinner. It should be remembered that thinner should
always be added slowly and the mixture stirred at the same time. |
If a definite livering has occurred, it is not
easily feasible to reclaim the material. A sample should be obtained for
evaluation. |
| C |
Use of improper solvent. |
Use recommended thinner. |
|
D |
Freezing (Latex) |
Store inside or above 32" F. If material has
freeze/thaw stability, do not agitate material when frozen. Allow it to
return to the unfrozen state undisturbed. |
|
NOTE: Primary causes of excessive bodying are:
use of old material, improper handling of dip tanks or mishandling of
other storage facilities. A method for keeping all storage tanks tightly
sealed should be arrived at and carefully adhered to. |
