SL420 filling wax

It is a filling wax containing 20% inert polymer filler. This type of wax has low viscosity and is suitable for industrial precision casting, producing components that are suitable for both thickness and thickness. This type of wax can be accurately and continuously produced, effectively reducing shrinkage and sedimentation rates to lower levels.

Characteristic

  • Good dimensional stability - it has superior dimensional stability because its linear shrinkage and settlement rates are kept to a minimum.
  • The high-strength model can maintain its shape even in high-temperature environments, and will not deform during contact, equipment, or polishing processes.
  • Low grayscale - grayscale below 0.03% to ensure no contamination of metals.
  • High productivity - able to accurately reproduce details with good surface finish.
  • Easy demolding - demolding is simple and fast.

Features:

Good dimensional stability - It has superior dimensional stability because its linear shrinkage and settlement rates are kept to a minimum.

The high-strength model can maintain its shape even in high-temperature environments, and will not deform during contact, equipment, and polishing processes.

Low grayscale - grayscale below 0.03%, ensuring no contamination of metals.

High productivity - able to accurately reproduce details and have good surface finish.

Easy demolding - demolding is simple and fast.


Application:

It can be used in paste or liquid form to better reduce shrinkage and settlement rates. Using it at low temperatures can improve production efficiency more; However, it is recommended to inject the liquid into the ceramic core at a slightly higher temperature.
