polyurethane and glue
« on: April 17, 2017, 01:00:03 PM »

Hello! I have a problem at work, where unwanted substance forms on the surface of the boots. I belive it's caused by polyurethane mixing with the glue in molten states.

Is there any way to keep it from happening or atleast lessen it? I can only mess with the glue so perhaps i can add some salt or liquid into it so they wouldn't react as much?

With best regards,
Lack

Its a little bit hard to understand the problem.  We'll have to work with it a bit at a time.

Bummer.

Quit melting it.  That'll solve the problem. 

OK, I know, you can't stop melting it.  I guess.  Its part of your process.  I have to guess.  'Cause you don't say.  Question: wouldn't glue stick if it weren't melted?  Or is it hot-melt glue?  You could also specify.

Why does it matter if it reacts or not?  Doesn't glue always stick?  Unless you call it glue, and you mean hot melt resin, or something.

Are you making polyurethane boots, and getting glue on them in your manufacturing?  Or is stuff hitting the floor and splashing on your boots?  You don't specify.  If that's happening, quit spilling it.

If this is really a chemical engineering question, try to specify your process.  Why is it this way, why does it have to be done this way -- those are questions you need to answer.

That all depends on how reasonable we're all willing to be.  I just want my friends back, except for Cartman, you can keep him.
