Documents and questions
Questions buyers ask about a grade
How does this grade differ from the other grades in its series?
If the part can be baked, use the oven route because it needs no additive. On a line that cannot be heated, the UV or catalytic route is the reason to choose this series over the heat-cured one.
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. 503590-70-3, 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?
Ask the technical contact for this grade.
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.
