Safety Instructions
• Do not open the furnace during preheating as this would cause aggressive combustion.
• The preheat furnace should only be fi lled to half of its maximum capacity.
• Investments contain quartz. Do not inhale the dust! Risk of lung damage (silicosis, lung cancer).
Recommendation: Wear a protective face mask, type FFP 2 EN 149:2001.
Prevent the release of dust when opening the bag and fi lling the mixing bowl.
• Rinse the empty bag with water before crumpling it up.
• Always moisten any dust before removing it from the workplace.
• After casting, place the completely cooled mould in water until it is fully moistened to prevent dust
when devesting.
• Use an extractor with a fi ne dust fi lter when sandblasting.
Changes
Revision marking April 2008 / Changes in relation to issue 02/2005.
Expansion control, vacuum stirring time, suitable casting ring systems, preheating process
We always attempt to include the latest results for our investment materials (development and appli-
cation) in the instructions. Excellent precision of fi t and surfaces are achieved with Kulzer equipment
and materials. The results may vary if other materials (e.g. casting ring liners, waxes, equipment etc.)
or diff erent techniques are used.
The fi gures given by our research and development department are guidelines and can be indivi-
dually adjusted.
