How to Choose the Right Release Agent for Your Silicone Moulds

Selecting the best release agent depends on your mould material, project style, and desired finish. Use silicone oil when you need regular mould care and frequent demoulding. Opt for glossy release film to achieve a high-gloss finish without post-processing. If you need a multi-surface solution or work in high temperatures, consider liquid release wax. Evaluate compatibility, ease of application, and finish quality to pinpoint your ideal match for each casting project.

Expert Tips for Cleaner Releases

Always apply release agent sparingly to avoid residue on your final resin work. Regularly inspect moulds for wear or residue build-up to maintain consistent release and high-quality surfaces project-to-project.
