Method of Application:
1. Melting directly
Before melting, please pretreat it firstly by dehumidify and dry.
Recommend temperature between 150°C-180°C.
2. Dissolve it by solution.
Recommend to use 10%~35% solid, appropriate heating and stirring could improve the effect of dissolution.

Remarks:
1) When making adhesive, the content of water in solvent should be less than 1‰.
2) It’s ok if mix several kinds of solvent.
3) If use swelling type solvent, it’s better to add the solution easy to be dissolved firstly, after TPU was dissolved totally, then add swelling type solvent again..
Usage:
For Printing ink, fabric combination, PU adhesive, heating transfer painting, etc.
