I' m currently making tensile test samples for Unidirectional (UD) Prepreg. Therefore, I need to fabricate a 1mm thick unidirectional sheet. I used two glass plates that sandwich five layers of UD Prepreg and are vacuum baged and cured in the Prepreg oven at 100°C (see attached pic). The two glass plates were treated with six layers of Easylease coated with a 20min. separation between each coating. However, I still have the problem that the Prepreg sticks to the glass. I cannot manage to take the Prepreg sheet off the glass without braking the glass or the prepreg sheet (see attached pic). I tired this several times already. Any Idea how to resolve this? What about trying to use PVA or wax as a release agent, instead of Easylease?

Looking forward fot some help

Kind regards

Pier

Also the shipping cost for overseas is often 4x the actual cost of the easylease.  Can you tell me what/ where I can buy a similar formulation stateside?

If you are in the United States, go to Krayden.com. They carry a product line from Locktite of frekote mold release agents. I use frekote 700 on my aluminum molds. Dont know if it works as good as easy lease because I couldn't justify the shipping cost to find out, but everything I have read and seen its the same thing. Works excellent for me.
