Addivion SE B15 is a solvent-based semi-permanent mold release agent formulated for composite manufacturing processes involving fiber-reinforced plastics, polyester resins, epoxy systems, and related thermoset matrices. Designed to provide multiple releases per application, Addivion SE B15 delivers a clean, consistent release surface that helps maintain part quality while minimizing mold preparation downtime. Addivion SE B15 is widely used in composite fabrication, wind energy blade production, marine vessel construction, and transportation component manufacturing.
Addivion SE B15 Overview
Addivion SE B15 utilizes a fluoropolymer-based active release chemistry carried in a solvent medium, enabling effective penetration and anchoring to mold surface profiles. Upon application and solvent evaporation, the fluoropolymer component bonds to the mold surface to form a durable, low-energy release film. This film resists displacement under the pressures and temperatures typical of thermoset composite curing cycles, providing repeatable release performance across multiple demolding operations. The solvent carrier assists in spreading the fluoropolymer uniformly across the mold face, ensuring consistent coverage on both flat and complex-geometry tooling. Addivion SE B15 is compatible with a range of thermoset systems and suited for hand lay-up, resin transfer molding (RTM), vacuum infusion, and related processes.
Key Features
- Multi-Release Performance: Addivion SE B15 is formulated to provide multiple demolding cycles per application under standard processing conditions. This reduces re-application frequency and supports higher throughput in production environments. Between release applications, molds can typically be wiped and reused without complete stripping, reducing line interruptions and associated downtime.
- Non-Silicone, Non-Transfer Formulation: Addivion SE B15 contains no silicone-based lubricants, significantly reducing the risk of silicone transfer to composite part surfaces. Silicone contamination can interfere with subsequent painting, bonding, coating, or secondary lamination operations. Parts released with Addivion SE B15 are generally amenable to downstream surface treatments without extensive decontamination procedures.
- Fluoropolymer-Anchored Release Film: The active ingredients include fluoropolymer components that anchor to the mold surface through chemical and physical interaction with the tooling substrate. This anchoring mechanism results in a more durable release film compared to purely sacrificial release systems, supporting consistent performance across extended production runs on steel, aluminum, and composite tooling.
- Compatibility with Common Thermoset Systems: Addivion SE B15 is suitable for use with unsaturated polyester resins, vinyl ester resins, epoxy systems, and related formulations. It is designed to remain effective under elevated temperatures and pressures encountered during standard composite curing cycles without causing surface defects or bonding anomalies in the finished part.
- Reduced Mold Fouling Tendency: Regular use of Addivion SE B15 supports cleaner mold conditions compared to wax-based or oil-based release systems. The low-transfer characteristics of the fluoropolymer film help reduce residue buildup on the mold face over time, helping to preserve dimensional accuracy and surface finish quality across extended production campaigns.
Typical Applications
Addivion SE B15 is applicable in composite manufacturing processes where consistent demolding performance and non-silicone release characteristics are required. It is particularly suited for fiber-reinforced polymer part production using hand lay-up, spray-up, resin transfer molding, vacuum bagging, and infusion processes. Addivion SE B15 performs effectively on standard open-face molds and closed tooling configurations made from steel, aluminum, glass fiber reinforced composite tooling, and similar mold substrate materials.
Specific application areas for Addivion SE B15 include wind turbine blade shells and structural components, marine hulls and deck structures, automotive and commercial vehicle body panels, transportation enclosures and structural fairings, aerospace structural and non-structural composite components, construction profiles, and general industrial composite parts. Addivion SE B15 is designed to support high-quality surface aesthetics and part integrity across these demanding end-use sectors.

Application Method
Apply Addivion SE B15 to a clean, properly prepared mold surface using a lint-free cloth or applicator pad. Wipe the product evenly across the mold face in overlapping strokes to ensure uniform coverage. Allow the solvent to fully evaporate before buffing the surface to a clear, even film. For initial mold conditioning or following a mold strip, multiple application and buffing cycles are recommended to establish the release film effectively. Allow the final coat to cure as directed before introducing the first production part. Confirm the specific application procedure, number of break-in coats, and cure conditions with the final technical data sheet prior to production use.
