Product Introduction

Deawa® DW-5213 is a semi-permanent, solvent-based mold release agent formulated for composite molding of epoxy, unsaturated polyester, and vinyl ester resin systems. A single application forms a smooth, continuous release film that allows multiple demolding cycles before re-coating is needed, helping composite manufacturers cut cycle time and reduce mold-cleaning labor compared with wax-based or single-use release agents.

Because DW-5213 is chlorine-free and leaves no visible residue or resin transfer on the part surface, it suits Class A finish applications — marine hulls, wind blade molds, RTM/infusion tooling, and pultrusion dies — where surface cosmetics and paint/gelcoat adhesion downstream both matter. It is not recommended for resin systems with special surface-preparation requirements (e.g. certain high-temperature prepreg or specialty coating systems); contact our technical team to confirm compatibility before switching an existing production line.

Key Properties

● Chlorine-free solvent system — no chlorinated residue transfer to molded parts

● Smooth surface release — forms a continuous, low-friction film for easy part separation

● Broad resin compatibility — suitable for most polyester, vinyl ester, and epoxy composite systems

● Room-temperature cure — dries and solidifies without heat, no oven cycle required

● No transfer, no residual film build-up — reduces mold cleaning frequency

Application Guidelines

1. Apply Deawa® DW-5213 to the mold surface at room temperature (below 60°C) in a well-ventilated area, using a clean, dust-free cloth. Do not use non-woven cloth — the solvent in DW-5213 will dissolve non-woven adhesive backing and contaminate the film. Work in one direction, brushing or wiping from one side of the mold to the other in an orderly pass.

2. Before the wet film evaporates, wipe the surface again with a new, clean, dry cloth, working from the outside of the mold toward the center in a circular motion, until the surface is dry and clear. This lays down the first release film layer, which should appear smooth and fully continuous with no streaking or missed spots.
