willferral Posted March 6 Share Posted March 6 I'm trying to buy some polycarbodiimide to use as a crosslinker as an alternative to polyaziridine. From what I've read they both work in a similar fashion. My problem is I can only find it as a waterbased crosslinker with about 60% of it being water. I want to use it with a solvent which wont mix with water.. Would it be possible to remove the water from it? I was thinking of heating it up and adding a solvent that wont evaporate at waters boiling point like xylene.. or maybe mixing it with Isopropanol and freezing it and then removing the frozen part? I'm not a chemist and I don't know the freezing or boiling point of Polycarbodiimide... Assuming it has a high boiling point or low freezing point and that I could do this, would this damage or change the polycarobdiimide? My other question is Is Polyaziridine still toxic after it has reacted with a resin and cured? As I can find that mixed with a solvent ready to go. Thanks for any help.

willferral Posted March 9 Author Share Posted March 9 After looking into this it looks like this chemical is sensitive to temperature and moisture. Link to comment Share on other sites More sharing options...
