Correct Application of Mold Release Agent for Polyester Resin

To achieve optimal results in polyester resin processing, it is crucial to use a high-quality mold release agent capable of ensuring excellent separation between the product and the mold. As suggested by RESINPRO, it is important to apply the mold release agent uniformly over the entire mold surface, avoiding build-ups and ensuring complete coverage.

Recommended Types of Mold Release Agents

RESINPRO recommends the use of silicone or wax-based mold release agents for polyester resins as they guarantee effective separation and facilitate the subsequent extraction of the artifact from the mold. On the website, a wide range of suitable mold release agents can be found to meet various needs, ensuring the selection of the most suitable product for your project.

Practical Application of Mold Release Agent

For proper application of the mold release agent, it is advisable to use a brush or sponge brush to evenly distribute the product on the mold. It is important to wait for the recommended drying time before proceeding with the polyester resin casting. Carefully follow the instructions on the mold release agent packaging to achieve the best results.

Useful Tips for Optimal Results

To avoid adhesion issues and facilitate artifact removal from the mold, it is recommended to apply multiple thin layers of mold release agent rather than a single thick layer. Additionally, it is important to thoroughly clean the mold after each use to ensure a longer lifespan of the mold release agent and better quality of the produced surfaces.
