Low-expansion refractory flour and sand for the ceramic shell
Remet Fused Silica LHT is very pure fused silica for building the ceramic shell. The material has low thermal expansion, excellent thermal shock resistance and low thermal conductivity. It is light and highly permeable, and the shell is easy to remove after casting. You use it for bronze, aluminium and steel. It is available as flour in 325, 200 and 120 mesh and as sand in 50/100, 20/50 and 10/20 mesh.
Key benefits
- Low thermal expansion: a dimensionally stable shell at high temperature.
- Excellent thermal shock resistance: the shell copes well with rapid temperature changes.
- Good insulator: low thermal conductivity.
- Light and permeable: a lightweight shell with high gas permeability.
- Easy knock-out: the shell is easy to remove after casting.
- Very pure: for a long slurry life.
Typical applications
- ✓ Flour for ceramic shell slurries
- ✓ Sand for stuccoing the shell coats
- ✓ Investment and art casting of bronze, aluminium and steel
Application
- Mix the flour with a binder, for example Remasol Adbond Advantage, to make a slurry.
- Dip the wax pattern into the slurry, let it drain and stucco the wet coat with fused silica sand.
- Use a coarser grain for each subsequent coat. This increases shell strength while keeping good gas permeability.
- Let each coat dry thoroughly before applying the next.
Points to note
- ✓ Avoid creating dust when pouring and mixing flour and sand, and do not breathe in the dust.
- ✓ Store the material dry and in its closed packaging.
- ✓ Other mesh sizes and larger quantities are available on request.
- ✓ This product is intended for the business market. For larger quantities or custom solutions, email info@siliconesandmore.com.
