Deawa DW-5380 is a solvent-based semi-permanent mold release agent supplied by Thousands Technology for composite molders who need verified release performance without transfer or residual buildup on the finished part. Deawa DW-5380 is formulated to leave a smooth, continuous film that is easy to separate from cured composite surfaces, and it is suitable for most polyester and related resin systems used in FRP production.

Key Characteristics of Deawa DW-5380
- No chlorine solvent
- Smooth surface, easy to separate
- Wide application, suitable for most polyester materials
- Dries and solidifies at room temperature
- No transfer, no residual on the molded part
Because the product is moisture-sensitive, it should be safely sealed when not in use and kept in a well-ventilated condition while being applied.
How to Apply Deawa DW-5380 Correctly
Following the manufacturer’s application guidance helps avoid common release defects. Always refer to the product safety data before use.
- Brush or wipe this release agent onto mold surfaces at room temperature below 60°C in a well-ventilated area, using a clean, dust-free cloth. Do not use non-woven cloth, since the solvent will dissolve the adhesive in non-woven material. Wipe the mold surface again with a clean, dry cotton cloth after coating to leave a smooth, continuous film.
- After the solvent evaporates, repeat the first coat to apply a second layer. Generally, 2 to 5 coats are required, with a 10 to 15 minute interval between coats; the film should be dry and not sticky before the next layer.
- Allow the final coat to cure for 20 to 30 minutes at room temperature. Lower ambient temperature will extend the required cure time, and the mold should not be used immediately after the final wipe; the film must solidify completely before the mold enters production.
- If release difficulty is detected, the whole mold can be re-coated, or just the area where the problem occurred.
- If the mold temperature is higher than 135°C, make sure the product is thoroughly dry before the mold is reused.
Sourcing Deawa DW-5380 Through Thousands Technology
Thousands Technology supplies this release agent as part of its auxiliary agent and additive range for FRP factories, boat builders, and composite part manufacturers. Working with verified, manufacturer-documented release agent data such as the specifications above helps molders avoid inconsistent demolding, surface defects, or unexpected cure-time issues in production. For broader testing context, buyers can also reference ASTM Committee D20 resources on plastics testing standards at ASTM International.
Frequently Asked Questions About Deawa DW-5380
Does Deawa DW-5380 contain chlorine solvents?
No, it is formulated without chlorine solvent.
Can I use a non-woven cloth to apply it?
No, a clean, dust-free cloth should be used instead; the solvent in the product will dissolve the adhesive used in non-woven material.
How many coats of Deawa DW-5380 are typically needed?
Generally 2 to 5 coats, applied with a 10 to 15 minute interval between coats, with each layer dry and not sticky before the next is applied.
What is the maximum mold temperature for use?
The cured film has a thermal stability of up to 330°C, and the manufacturer’s recommended application temperature range is 13 to 135°C; above 135°C, the product must be thoroughly dry before the mold is reused.
Can I request a technical data sheet for Deawa DW-5380?
Yes, buyers can request the current technical data sheet and batch documentation directly through an inquiry to confirm specifications for a specific order.
