Semi-Permanent Mold Sealers

Semi-permanent mold release systems differ from sacrificial mold releases. Although they require more time to apply, they do not need to be reapplied every time the mold is used, therefore saving a lot of time over the life of a mold.

Freeman has a complete line of semi-permanent release agents, primers, sealers, and mold cleaners.
