Grunde, The HumiSeal 1B73AP is supposed to reduce the occurrence of webbing, that's why it was original chosen. Now that we switched over to the 1B73 we are seeing signs of it and trying to stay on top of it. We reduced the atomizer a little to try to keep it to a minimum, I am not sure how much that is going to help. I have seen worse on one of our other coaters spraying HumiSeal 905. We are currently using a PVA coater and spraying it on.

Do you use spray or filmcoating? Cheers, Grunde Is anyone currently using HumiSeal 1B73AP mixed with 521 carrier in a automated process? If so have you noticed any coating issues?
