polyurethane tackiness
polyurethane tackiness
(OP)
Team I had a molded very thin wall polyurethane rubber
After the molding the parts are so sticky that I put them into a chlorine bath
The problem is that after the wash the parts suffer from discoloration
There is any alternative lubricant/coating to decrease this tackiness and stiffness ?
Taking into account that this is a medical application.
Regards

some oils might work. Might be worth talking to a chemist.

RE: polyurethane tackiness
Did you perhaps not put in a full amount of "hardener" expecting to get a finished product with a lower durometer (lower stiffness)? That don't work. Get a compound that is formulated to cure at a lower durometer, and mix at the recommended ratios.
