A multi-purpose silicone release agent made of a blend of silicone oils and resins in a convenient aerosol spray can. Pol-Ease 2300 is an effective release for most Polytek products but should not be used before pouring or brushing liquid silicone mold rubber – in this case Pol-Ease 2500 is the proper choice. Brushing out the release with a soft brush can improve results.
