It is readily biodegradable and is not a hazardous material under current occupational health and safety and transportation regulations.
Suitable for epoxy and polyester resins. Dyed violet for better processing.
- Silicone free

Processing:PARTALL® Coverall Film is supplied ready for use and should not be diluted. It is to be applied by means of a spray gun or a brush/sponge. Further processing information in the technical datasheet
PARTALL® Coverall Film is suitable in combination with release agent Semiperm™ Monofilm as a safe release agent for silicone moulds. This combination provides a barrier layer so that casting with epoxy resins is also possible without any problems. The service life (durability) of the moulds is significantly extended.
The release agent Semiperm™ Monofilm is applied with a brush. After flash-off, an application of PARTALL® Coverall Film PVA is made, also with a brush or sponge. The PARTALL® Coverall Film PVA transfers to the casting are washed off with water after demolding and reapplied before each impression.
