Overview
DeawaDS-13 is a mold sealant specially designed for metal and fiberglass molds with micro-pores, slight scratches, and surface defects. As one of the recommended international brand products in our auxiliary agent range, DeawaDS-13 can be used in conjunction with a Deawa release agent to greatly improve overall release effect, and is supplied with supply chain resource support for fabricators sourcing a mold sealant for composite tooling.

Why Sealing Micro-Pores Matters
Metal and fiberglass molds develop micro-pores, scratches, and small surface defects over repeated production cycles, and these imperfections can telegraph through to the finished composite part if left unsealed. Because DeawaDS-13 penetrates rapidly and cures within minutes, it is designed to fill these imperfections quickly without holding up production between mold preparation and the next molding cycle.
Its high durability is also relevant for fabricators running multiple parts off the same mold, since a sealant that breaks down quickly under repeated release cycles would need to be reapplied more frequently, adding labor time to each production run.
Mold Preparation
For best results, all waxes, sealants, scrubbers, and other release agent residues must be thoroughly cleaned before applying DeawaDS-13. Formulators can choose deawa 577S mold cleaner, deawa 553S mold cleaner, or other cleaning solvents for this step.
Application Method
This sealing agent can be applied at room temperature using a clean, lint-free cloth. Nonwoven fabric should not be used, since the product’s solvent will dissolve the adhesive in nonwoven fabrics. Always refer to the product safety data sheet before use.
- Use a clean, lint-free cloth to apply the sealing agent to the mold, then immediately use another clean, lint-free cloth to spread it from the outside in, ensuring the film formed on the mold is a continuous, even, thin layer.
- Repeat the above step and apply two layers total, with a 15-minute interval between applications. For new molds, apply two additional layers of sealing agent.
- After applying the final layer, cure at room temperature for 30 minutes before applying the release agent.
Precautions and Storage
DeawaDS-13 is sensitive to moisture, so the lid should be tightly sealed when not in use, and good air circulation should be ensured during application. It should be stored in a dry, cool, well-ventilated location, with the lid kept sealed whenever the product is not actively being used.
What to Consider When Sourcing This Product
When sourcing a mold sealant for metal or fiberglass tooling with surface imperfections, fabricators typically evaluate cure speed, filling performance, application temperature range, and compatibility with their existing release agent system. Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new sealant for a production line.
Because this sealant is designed to work alongside a separate release agent rather than replace one, buyers should confirm their current mold cleaning and release workflow can accommodate the recommended cure and interval times before switching products.
