KALSINT is a plaster free phosphate-based special investment compound for production of duplicate casts and dies for Cobalt Chrome model casting techniques and combined work.

2. Important Instructions:

1. KALSINT must not be brought into contact with plasters or plaster containing materials / containers.
2. Please use special mixing cups and spatulas for KALSINT
3. KALSINT must be stored under cool and dry conditions
4. KALEXPAND must be stored at a temperature between 20 to 22ºC.
5. The stability of the product is 36 months for KALSINT and 24 months for KALEXPAND.

3. Production of models and casting moulds

3.1 Premix the liquid and powder by hand in a clean bowl. Then mix under vacuum for 30 seconds.
3.2 Pour the mixed investment into the duplicate under vibration. To guarantee a smooth and hard surface on the models it’s important to maintain the vibration for 2 minutes.
3.3 Dry the model for approximately 40 minutes in a furnace at 220-240ºC. After drying the models they may be hardened using any system. If silicon moulds are used, no hardening is necessary
3.4 Investing: Preferably use fine investments for the first coat or degrease the wax sufficiently and invest dry.
3.5 After setting for 35 – 40 minutes put the moulds in the furnace, preferably cold, at 240 ºC for 40 minutes.
3.6 When the moulds are dry, programme the temperature for casting at 950ºC for partial pieces and 1.080ºC for whole plates. Maintain this temperature for at least 35 minutes.
3.7 Cast as per the instructions of the alloy manufacturer.
3.8 Let the casting cool down to room temperature. Never use water to cool while the metal is red hot.

Note: The best expansion rates are obtained at a heating rate of 50C per minute. If the indicated drying times and pre-heating temperatures are not observed, slight fissures in the muffle surface may occur; they are of no importance for the cast object.

Safety information:

Avoid the formation and breathing of the dust. (It contains silica)

Work in well-ventilated areas or with aspiration.

Mixing with other liquids or materials during use must not be carried out, since during this process health hazards as well as impairments to the casting quality cannot be excluded.

If KALEXPAND contacts the skin, wash with plenty of water.
If KALEXPAND contacts the eyes, rinse thoroughly with plenty of water keeping eyelid open. In case of persistent discomfort please see your doctor.
Mixing liquids are alkaline.

1. Technical Data

2. Important Information:

1. KALVEST must not be brought into contact with plasters or plaster containing materials / containers.
2. Please use special mixing cups and spatulas for KALVEST
3. KALVEST must be stored under cool and dry conditions. The coating is sensitive to moisture: prolonged exposure to the air may alter the characteristics of the product
4. KALEXPAND must be stored at a temperature between 20 to 22ºC.. Prolonged exposure to temperatures lower than 5 °C or higher than 35 °C may produce freezing and / or destabilization of the product. Keep the packages tightly closed after each use. Prolonged exposure to the air may cause crystallization
5. The stability of the product is 36 months for KALVEST and 24 months for KALEXPAND.

3. Expansion control:

1. Expansion can be adjusted for precise control of any type alloy.
2. Maximum expansion is obtained by using 100% KALEXPAND liquid.
3. To obtain less expansion, use smaller quantities of KALEXPAND liquid with larger quantities of distilled water-to a maximum ratio of 50% distilled water and 50% KALEXPAND liquid. Please follow chart given earlier.

4. Instructions

1. Dilute KALEXPAND with distilled water for the desired combination
2. Line the casting ring using a moistened cellulose liner
3. Fix the wax fabrication in place with wax on the sprue base former.
4. Coat the wax model with a wetting agent (Do not use excess wetting agent.)
5. Measure KALVEST powder – 1X ring 60 grams, 3X ring 300 grams
6. Add the powder to the liquid, and shake vigorously for 15 seconds. Mechanically spatulate for 50 seconds under vacuum, and vibrate the mix into the casting ring for 10-15 seconds.
7. Setting is complete in 30-45 minutes depending on the size of the casting ring.

5. Pre-Heating: After bench setting, place the casting ring into a cold furnace, and dry it by raising the temperature in the furnace to 250-300°C. Hold for 30-60 minutes-depending on the size of the casting ring. Raise the temperature in the furnace to the desired burnout temperature, and hold for 30-60 minutes depending on the size of the casting ring. The rate of climb for the furnace temperature should be 7-9 ºC per minute. 

6. Burnout: Suggested burnout temperatures are:
700 - 750°C for precious alloys
800 - 850°C for semi-precious alloys
850 - 920°C for non-precious alloys

After the casting has been completed, bench-cool the ring to room temperature. Do not quench in cold water

Safety information:

1. The coating contains quartz powder. DO NOT INHALE THE POWDER! Continued inhalation of the powder may cause silicosis.
2. During handling, avoid the formation of powder. Prevent inhalation with a protective mask, type P-2. Eliminate any spillages of powder with a damp medium.
3. Avoid the formation of powder during demuffling by submerging the cylinder completely cold in water.
4. Aspire and extract to the exterior the ammoniac vapours from the pre-heating.
5. Avoid skin contact with the mixing liquid KALEXPAND. In the event of contact wash with soap and water.
6. In the event of contact with the eyes, wash under abundant running cold water and consult a doctor.
