Expansor - liquid for high precision coating for the casting technique on model.
Technical data:
Put the model of a fine coating or treat it with a regulatory agent.
- To fill the cylinders, use the expansor liquid, diluted to 50% water.
- If this ratio is not respected, cracks could appear on the surface of the cylinder. Fill the cylinder over a vibrator.
- Unmolding after 35 minutes.
Calibra-M, after 35 min, bake the cylinders preferably in a cold oven.
- Program the flow temperature at 950 ° C.
- Maintains for at least 45 minutes at 240 ° C.
- The best expansion is obtained with a heating at the rate of 5 ° C/minute.
Calibra M, after maintaining the oven, do the casting as usual.
- After the casting, wait until the masselotte is redder.
- Once the cylinders are slightly cooled in the open air, immerse them completely in the water.
- In this way, demouflage becomes very easy.
Calibra-M® powder: Store at 18-25ºC. Maintain well closed packaging out of humidity.
This coating is sensitive to humidity, prolonged exposure to air can alter the characteristics of the product.
- Expansor Store at 18-25ºC: prolonged exposure to a temperature below 5ºC or greater than 35ºC can cause freezing and/or destabilization of the product.
- Maintain well closed packaging after each use.
- Prolonged air exposure can cause crystallization.
Duplicate model: For 200 g of powder, use the following mixture: 14-15 ml Expansor + 14-15 ml distilled water.
Cylinder: For 400 g of powder, use the following mixture: 30-32 ml Expansor + 30-32 ml distilled water.
Prepare the liquid according to the desired concentration, add the powder to the liquid and vigorously mix 60 s.Mechanical mixture under vacuum, for 30 s.
Delivery: Liquid for Ceramvest, Calibra, Acuavest - 1 liter coating
