Waterproof Coating Waterproof coating is a post-processing technique that applies a protective layer to 3D printed parts, enhancing water resistance, chemical stability, and durability. It prevents moisture absorption, deformation, and degradation. Common waterproof coatings include epoxy resin, polyurethane spray, and hydrophobic sealants. Proper surface preparation, including sanding and cleaning, ensures adhesion and smooth finish. Advanced formulations provide UV resistance, flexibility, or transparency. Waterproof coating expands functional applications for outdoor products, aquatic devices, and airtight enclosures, enhancing durability, reliability, and safety. |
