Flash dressing for use in foundry practice |
(57) This invention relates to flash dressing compositions for use in foundries comprising
a mixture of diacetone alcohol and a C
1,-C
4 monohydric alcohol. These mixtures have a flash point above 90°F which meets the
safety requirements against fire hazards. In spite of this they are not difficult
to ignite or burn-off completely from the castings on which they are applied. They
are also less expensive than dressings commercially available hitherto.
