RE: Substitute For Diesel Used As Concrete Form Oil

Judy—

I believe there are vegetable oil-based release agents. http://www.precast.org/publications/mc/TechArticles/03_Winter_Form_Release_Agents.htm I’ve also heard of glycerol/glycerin (of which there’s a glut from biodiesel production) being used but I don’t have details.

Subject: Substitute For Diesel Used As Concrete Form Oil

Hello, All--

We are looking for a less toxic substitute for the diesel commonly used as a release agent for concrete forms. Does anyone know of a possible substitute that won't be prohibitively expensive?
