When creating parts from molds—or even molds themselves—applying a release agent is an important step in the process. Mold release agents serve two basic purposes:

Mold releases act as a parting agent between layers of resin and the mold surface, so that cured parts can be removed without damaging the part or the mold.
When applied properly, mold releases help create a durable, high-gloss surface finish for finished parts.
Mold Releases help to preserve the integrity of your part and avoid damage to both the part and mold. The effort required to apply a quality release agent during preparation far outweighs the hours spent correcting damage later.

The waxes in this category, including Partall® Paste Wax and Meguiar's Mirror Glaze®, should be wiped on using a soft, clean towel. For best results, liquid release agents, including PVA and FibRelease®, should be sprayed on using an appropriate tool, like our Preval Sprayer.
