We use PU glue to coat hook & loop. We add solvent and hardener. The fiber is too hard, what should we do to make it softer?

Please try to reduce the percentage of hardener. If the bonding becomes poor and the fiber is still too hard, you need to choose Nanpao Specializer PU resins for velcro tape sizing. Please kindly refer toNanpao AT-33S andNanpao PN-70 Cross-linker.
