Documents and questions
Questions buyers ask about a grade
How does this grade differ from the other grades in its series?
Within this series the grades differ mainly in viscosity and in how much ceramic residue they leave: the thin ones for a 4 µm film, the thick ones for a build coat, the high-yield ones where the film is a precursor rather than a coating.
What is the HS code for export?
HS code 3911900090, the code the grades are exported under from China. Ask for it on the proforma invoice when your broker needs it there.
Is it a single-component material, and what is its CAS number?
One component. CAS No. 475645-84-2, as listed in the technical data above. Ask the technical contact for this grade.
What do I do with what is left in the container after opening?
Storage and shelf life: Shelf life 12 months.
Polysilazanes react with water and alcohols: close the container after use.
What is the smallest sample, and how quickly does it arrive?
Samples from 10 g, charged, with air freight included in the sample price.
Industrial-scale production line, bulk filling, consistent quality, large-volume supply.
