Release
Detailed information:
(1) Separation of a cured or baked product from the metal mold or pan in which it is formed. Common release agents for rubber and plastics are waxy or fatty materials such as paraffin and tallow; vegetable oils are used in the baking industry. Such materials are collectively called abherents.(2) Gradual diffusion of an active ingredient through a permeable or soluble coating. Pelleted products such as fertilizers and medicinals are often covered with a layer of a substance that permits slow and uniform escape of the active principle. Sulfur is used to coat controlled-release fertilizers; gelatin and similar materials serve the same purpose in pharmaceuticals.
