1Silicone Preparation

To prevent air bubble formation in the silicone casting, it is essential to carefully follow the manufacturer's instructions. Make sure to accurately weigh the components and mix them thoroughly to avoid trapping air bubbles.

2Degreasing Agent

RESIN PRO recommends using a degreasing agent such as RESIN CLEAN degreaser to thoroughly clean the mold before pouring the silicone. This will help eliminate any grease or dust residues that could cause air bubble formation.

3Silicone Degassing

To remove air bubbles from the silicone, it is advisable to use a vacuum chamber for degassing. RESIN PRO offers high-quality vacuum chambers that allow for bubble-free silicone, ensuring professional results.

4Casting and Bubble Removal

During the silicone casting process, pour the material slowly and steadily to minimize air entrapment. To eliminate any air bubbles on the surface, you can use a soft brush to move them towards the edges. RESIN PRO provides high-quality accessories and tools to facilitate this process.
