Many mold making and casting projects require the use of an appropriate sealer and/or release agent. In the realm of mold making and casting, these two products are broadly defined as follows:
Sealer- a material that seals small pores/holes so that liquid mold material cannot penetrate the surface. Sealers fall into three general categories: permanent, semi-permanent and removable.
Release Agent– a coating that is applied to prevent liquid rubbers and resins from sticking to surfaces. Release agents can be categorized into two general categories: those used for mold making and those used for casting (one release agent can be used for both purposes in some instances).
