Question 1

What substrates can NHA-50 bond effectively?

Accepted Answer

NHA-50 adheres to leather, synthetic leather (PU/PVC), rubber, EVA foam, ABS, and fabric-backed vinyl used in automotive interiors. Surface priming with a polychloroprene-compatible primer improves adhesion on low-energy plastics and improves long-term durability.

Question 2

What application temperature and open time should be expected with NHA-50?

Accepted Answer

NHA-50 is applied at 110–130°C from a slot die or nozzle applicator. Open time is 8–15 seconds at ambient conditions; reducing melt temperature extends open time. Assemble within the open window and apply 0.2–0.4 MPa contact pressure for 5–10 seconds to activate the bond.

Question 3

How does NHA-50 perform under oil and wet conditions?

Accepted Answer

The polychloroprene base chemistry provides inherent resistance to aliphatic oils, greases, and prolonged water immersion. Bond integrity is maintained after 100-hour water soak at 40°C, making it well suited for footwear outsole bonding and automotive under-hood trim applications.
