Investment

– Mix max. 400 g investment material in one go.

– Closely observe mixing ratio!

– Investment is carried out on a shaker under slight vibration. Allow the investment ring to set without

manipulating it.

Some aspects influencing the setting expansion of the investment material

– Temperature of the investment material and the liquid

– Residual water in the mixing cup, atmospheric humidity

Preheating / holding times

Starting temperature Room temperature

Temperature increase 5 °C / 41 °F per min

Holding time 30 min at 250 °C / 482 °F

100-g investment ring – min. 45 min

Holding time after reaching

200-g investment ring – min. 60 min

the final temperature (850 °C / 1562 °F)

300-g investment ring – min. 90 min

If more than 2 investment rings are preheated at the same time, the holding time at the final temperature

has to be prolonged by 15 minutes per additional investment ring.

Important information

– Do not use a debubblizer (tenside). Reactions with the investment material may occur.

– Consistent results can only be achieved under consistent conditions and if the Instructions for Use are

observed.

– Dilute liquid exclusively with distilled or de-ionized water.

– Liquid concentration: The more distilled or de-ionized water is added to the mixing liquid, the lower the

setting expansion. Do not dilute the liquid to below 50%.

– Use only dry, clean instruments to process the investment material. Do not use plaster mixing cups.

– Carefully cut open the powder bags and remove the entire contents of the bags.

– The stipulated minimum setting and holding times must be closely observed.

– Do not invest under pressure since this changes the product properties.

– Do not invest over the weekend (risk of cracks and press flashes).

To ensure thorough heating of the investment rings in the preheating furnace, the following points

have to be observed:

– Always place the investment rings into the cool preheating furnace.

– Load the preheating furnace to maximally half of the available utility space.

– Always place the investment rings in the rear part of the preheating furnace.

4

– Always place the investment rings in the preheating furnace with the opening facing down and at an

angle of 45°, if possible.

– Do not place the investment rings in direct contact with each other. Allow air circulation.

– Always remove pressed investment rings from the press furnace immediately after the end of the program

and place them on a grid for cooling.

– When divesting, ensure to only sandblast (4 bar pressure) the excess of the investment material and not

the ceramic object.

IMPORTANT! Safety notes

– Do not open the furnace during the first 20 minutes of preheating: Burn hazard caused by wax fumes that

might ignite in the air!

– This material contains quartz, which may cause lung diseases (silicosis or cancer) when inhaled. Prevent

the inhalation of dust and wear a suitable dust mask.
