A release agent (also mold release agent, release coating, or mold release coating) is a chemical used to prevent other materials from bonding to surfaces. Release agents aid in processes involving mold release, die-cast release, plastic release, adhesive release, and tire and web release. [ 1 ]
The gelcoat is pigmented resin, and gives the mold surface a harder, more durable finish. Once the release agent and gelcoat are applied, layers of fiberglass and resin are laid-up onto the surface. The fiberglass used will typically be identical to that which will be used in the final product. In the laying-up process, a layer of fiberglass ...

The processing steps are very similar to those in hand lay-up. In this process, the release agent is first applied to the mould and then a layer of gelcoat is applied. The gelcoat is left for two hours, until it hardens. Once the gelcoat hardens, a spray gun is used to deposit the fibre resin mixture onto the surface of the mould.
A release agent, usually in either wax or liquid form, is applied to the chosen mold to allow the finished product to be cleanly removed from the mold. Resin—typically a 2-part thermoset polyester, vinyl, or epoxy—is mixed with its hardener and applied to the surface. Sheets of fiberglass matting are laid into the mold, then more resin ...
Alternately, resin casting may be accomplished with a resin plus a nearly equal amount of a "hardener" liquid (as in many epoxy resin or polyester resin systems), which functionally contains a second polymer, for use in forming a final product plastic which is a copolymer. Copolymers contain two different alternating chemical entities in the ...
An adhesive bandage with a release liner partially removed. Commercial coating companies deal with a lot of different end uses of this industry. They provide unique solutions to their customers, based on a wide variety of substrates and an endless combination of release agents with specialized properties.
