Removing polymer release agent
We are using structural high density foam to pour in Epoxy mold.
But prior of Pouring we spray the mold with Polymer base release agent and then applying the Polyester Gel coat by means of spray, then we pour the material into the mold in order we can have a post finished molded part.
The problem we are having is getting rid of the release agent which was applied in the mold prior of the pouring. We solved a problem but we are stuck with another one, which we are having hard time in getting adhesion between the material and the paint.
I am looking to use a type of a release agent which will not create problems in painting the produced parts.B.J. Najarian

The best mold release agent for different rubber compounds is Dupont TraSys Release Agent, based on product evaluation and field trials.Russ Cano

Hi, Russ. Thanks. Please tell B.J. what kind of paint you applied to your rubber compounds, and what process you used to remove the mold release, when your shop determined that the Dupont product solved the paint adhesion problem; it's not immediately clear to me how this product fixes his problem. Thanks again.
