Ceramsite powder 200 mesh
Product introduction of Ceramsite powder 200 mesh
Ceramsite powder 200 mesh always works as a refractory coating for precise casting. For the resin molding sand or water glass molding sand casting process, the surface of the mold cavity needs to be coated with paint before the box is poured in order to avoid the phenomenon of sand sticking on the surface of the casting. The alcohol-based coatings are efficient foundry coatings. It can improve the surface of casting steel and reduce energy consumption. But traditional alcohol-based coating has poor fluidity, has obvious brush marks after painting. In the meantime, the coating is not easy to clean. As a kind of spherical sand, ceramsite sand could make a coating with good fluidity. It also has advantages such as high refractory temperature, excellent wear resistance, etc. Ceramsite sand is a new type of material for alcohol-based coatings. The specification always goes 200mesh for Ceramsite sand for Molding sand Alcohol-based coating.

Product Feature of Ceramsite powder 200 mesh
- Ceramsite sand is spherical sand blown out of fused bauxite, so it has high refractoriness.
- The particle shape is spherical, the ball breaking rate is low, the alcohol-based paint has good fluidity, and the paint has no agglomeration and brush marks.
- Good suspension stability, not easy to flow out.
- Ceramsite sand has high strength, and the alcohol-based paint is not easy to crack and has no bubbles.
- It is easy to clean up after use and has good anti-sticky sand performance.
- Cost-efficient, replace zircon powder.
Applications of Ceramsite powder 200 mesh
Resin sand casting coating
Water glass sand casting coating

Q: Are you a manufacturer?
A: Yes, Our factory was founded in 1999. We are experienced manufacturer of foundry ceramic sand.
Q: What are the key quality indexes of ceramic foundry sand?
A: First of all, the Al2O3 content. We have three grade:75% Al2O3 ceramic sand,73% Al2O3 ceramic sand,70 Al2O3 ceramic sand.
Secondly, the particle size distribution of ceramic sand. We will provide samples according to the customer’s requirement. And make the same particle percentage coincide with confirmed sand.
Q: Where is the nearest port from your factory?
A: Qingdao and Tianjin are both near to us.
Q: What is the HS code of ceramsite sand?
A: Since there is no specific HS code for ceramsite sand, there are HS codes 69149000 and 68159990 suitable for exporting ceramsite sand. But with our experience, HS code 68159990 is easier to do custom clearance with no risk to be inspected.
Q: How do you operate the QC system?
A: Before shipment, we will take 1 day to check the chemical composition for every bag. Our QC staff will take another day to check particle size distribution for every bag. We will reserve samples from each batch production in case there is anything wrong.
Q: What is the lead time for each order?
A: It depends on the quantity and sand size required. Generally 5-10 days for FCL（20-25MT）.
