Seek PVA crosslinking agents as alternatives to boric acid
Thread Content
Due to product exports, boric acid cannot be used; an alternative to boric acid is urgently needed as a crosslinking agent for PVA under normal temperature and pressure conditions. QQ: 834183947 Phone: 13527102365
There are several other PVA crosslinking agents that can replace boric acid; it depends on whether you can use them, such as aldehyde-containing organic crosslinking agents like formaldehyde and acetaldehyde – presumably the export of these is also restricted. There are also some other available organic crosslinking agents; for more details, please contact me on QQ: 1982634988
