I’m trying to replace the silicone and FEP layers in my v2 hard vat. I poured QSil 216 silicone and it came out crystal clear overnight. It was easy to do.
But I’m having problems adhering an FEP layer.
First, I cut a piece of mUVe FEP sheet to fit and used light soapy water and a roller to suction it onto the silicone. Then let it sit overnight. But this pulled up easily on the first print’s base layer.
Second, I scuffed the FEP bottom surface with 600 grit (300 seemed way too coarse). But it was very cloudy after adhered, and it pulled up easily too.
Third, I sandwiched a piece of 3M 467MP double-sided adhesive between the mUVe FEP and silicone. This stuff is very cloudy and did not clear up when applied with light soapy water. And it was a bear to apply. It did have excellent adhesion. But I don’t want to use it because its not optically clear.
Anybody have experience getting FEP to stick? I’m at a loss. I’m not sure how Kudo is doing it. mUVe FEP is a little thicker than the Kudo film. I’m wondering if perhaps I should seal the mUVe FEP edges with silicone to keep a vacuum under the film?
