Use Tips

1. Qihui makes adhesion from low to high level. Take necessary tests to find out the suitable adhesion for your application. If you do not know which one is the right, please send your material to Qihui lab, we can test for you and offer professional suggestion.

2. Before lamination, your material surface should be clean and dry, free from dust, oil, solvents or other chemicals, otherwise the chemical reaction would happen with our film adhesive and caused residue.

3. Use laminating machines with rubber rollers, it will help to eliminate air bubbles.
