Addivion RA 700 is a semi-permanent, non-silicone mold release agent based on a solvent-based polymer release chemistry, formulated in an aliphatic hydrocarbon (naphtha-based) solvent carrier for composite manufacturing and industrial molding operations. Applied as a thin wipe-on coating, Addivion RA 700 forms a durable, dry release film on mold surfaces that enables multiple part releases per application cycle without silicone transfer or mold contamination. Addivion RA 700 is widely used in fiberglass reinforced plastics, advanced composite manufacturing, aerospace tooling, automotive components, wind energy blade production, and marine composite fabrication.
Addivion RA 700 Overview
Addivion RA 700 is a solvent-carried polymer mold release agent designed to replace older chromate-based and silicone-based release systems in demanding composite molding environments. The product is applied by wiping onto a clean, bare mold surface with a lint-free cloth, allowing the hydrocarbon solvent carrier to evaporate and deposit a thin, uniform release film. This film provides a low-energy surface that prevents adhesion between the cured composite part and the mold tool.
Multiple sealing coats are typically applied during initial mold preparation to build up an effective release layer, and subsequent maintenance coats are applied between production cycles to restore release performance. Addivion RA 700 is compatible with a broad range of thermoset resin systems including epoxy, unsaturated polyester, vinyl ester, phenolic, and bismaleimide composites, and can be used on aluminum, steel, and composite tool surfaces at application temperatures up to approximately 135°C.
Key Features
- Semi-Permanent Multi-Release Performance: A single application supports multiple part releases before recoating is required, reducing labor and material consumption compared with sacrificial wax or PVA release systems.
- Non-Silicone Formulation: Free of silicone, eliminating the risk of silicone transfer onto composite part surfaces that can interfere with downstream painting, bonding, or secondary finishing operations.
- High Gloss, High Slip Release Film: Produces a smooth, high-gloss release film that supports clean, low-friction part release and a good surface finish on the molded part.
- Broad Resin Compatibility: Effective on epoxies, polyester resins, vinyl esters, thermoplastics, rubber compounds, and most other molded polymer systems.
- Dry, Non-Marking Film: After solvent evaporation, Addivion RA 700 leaves a thin, dry, transparent film that does not cause surface marking or print-through on composite parts. The dry film is stable during resin infusion and layup operations, supporting surface quality and dimensional consistency in the molded part without interfering with fiber wet-out or resin flow.
Typical Applications
Addivion RA 700 is used in composite molding operations where a reliable, residue-free mold release is required across multiple production cycles. In fiberglass reinforced plastic fabrication, Addivion RA 700 enables clean part release from gel-coated and non-gel-coated tooling. It is also applied in aerospace composite tooling, automotive component molding, wind energy blade production, and marine composite fabrication, where high gloss finish and freedom from silicone contamination are valued.

Addivion RA 700: Safety & Handling
Addivion RA 700 should be handled in accordance with applicable safety procedures for flammable solvent-based products. Users are advised to review the Safety Data Sheet prior to handling and to implement appropriate personal protective equipment and engineering controls as specified therein. Addivion RA 700 should not be used in enclosed spaces without mechanical ventilation.
Addivion RA 700 must be kept away from oxidizing materials and strong acids during storage and handling. Containers should be grounded during transfer operations to prevent static discharge. In case of skin or eye contact, rinse with water for an extended period and seek medical attention if irritation persists. Spills should be contained using non-combustible absorbent materials and disposed of in accordance with local regulations for flammable solvent waste.
