Sulfurous Anhydride and Polyurea

02/11/2007 12:45 PM

I do have an application with polyurea that will be in contact with anhydride sulfurous at different concentration. Does anybody have an idea of the tolerance of the polyurea in contact with this product?

Thanks

Do you mean anhydrous sulfuric by sulfurous anhydride?

If your polyurea is urea formaldehyde resin of high density it will not react till it is anhydrous.

the translation might be wrong from my part. In french, this is ``acide fluoridrique``.

I am sorry, english is not my first language.

Try using chemical formulas. It would help to be sure.

If you are referring to ' HF ` the outlook is not good.
