Coating process stripe problem!

2009-03-20View Original

Thread Content

Recently, streaking problems often occur in the silicone oil coating of release films. Could you please help analyze the specific reasons? ?

Is it because the silicone oil is too thick and has poor leveling properties?

What you said above makes sense. Poor leveling and dispersion will affect the coating quality. And will the drying process have any impact? For example, when blowing the wind.

There are also many speed ratios due to the stability of mechanical tension.
