Hi,
I need to develop a PU coating resin that bonds to polypropylene.
It needs to be a 2K solvent borne system and it's for a textile so it must be reasonably flexible.
The isocyanate must be aliphatic.
I am not looking for a soft PU dispersion for textile coating but rather a fairly tough but flexible coating, e.g. as for plastics.
Can anyone suggest a starting point? Will it be mainly the polyol that determines how well (or if) the resin bonds to PP?
any help I can have will be much appreciated. Thanks !
