I don't think THEY (Humiseal) know how their material cures. I have a data sheet from them for 1B73, and it says 24 hours at room temperature or 30 min. @ 170�F. We use our in-line oven mainly to dry the material and make it tack-free. You would

Hey guys, just joined the site and I'm looking for some help. In our coating department we are running a Asymtek C-740 with a Jet and film coater. The coating that we are using is Humiseal 1B73 acrylic. The problem that we are having is that the C

dave, where I work they are having the same problems with 1B31 acrylic. The coating thickness is 6-8 mils dried so that have to do several passes with an air dry between them and a final oven cure. They think that it might be related to the heating r

Good morning Jamie. I work at a CM and can offer some input on process flexability. I do not have any data on how reliable the coating is but I can say that they are both very difficult to control. Will you be selective coating or full coating? Ho
