Addivion RA 700 is a semi-permanent, non-silicone mold release agent based on fluoropolymer technology, formulated in an isopropanol 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. The isopropanol carrier provides a higher flash point compared to heptane-based alternatives, making Addivion RA 700 suitable for facilities with stricter flammability controls. 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 fluoropolymer 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 isopropanol solvent carrier to evaporate and deposit a thin, uniform fluoropolymer 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; 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.
Key Features
- Isopropanol-Based Solvent Carrier: Addivion RA 700 uses isopropanol as its solvent carrier, resulting in a higher flash point compared to heptane-based fluoropolymer release agents. This characteristic makes the product more suitable for production environments subject to stricter flammability regulations or where lower vapor pressure solvents are preferred. The isopropanol carrier evaporates cleanly, leaving a uniform fluoropolymer film without solvent residue on the mold surface.
- Semi-Permanent Release Film: The fluoropolymer coating applied by Addivion RA 700 is semi-permanent, persisting through multiple molding cycles after an initial preparation sequence of sealing coats. Once a mold is properly sealed, a single maintenance application can sustain release performance across several consecutive part pulls. This multi-release capability reduces production downtime and lowers the frequency of mold preparation compared to sacrificial wax-based systems.
- Non-Silicone, Non-Chromate Chemistry: The product contains no silicone compounds and no hexavalent chromium, eliminating silicone contamination risk and providing compliance with environmental and occupational health regulations that restrict chromate use. A silicone-free film ensures downstream bonding, painting, and coating operations are not compromised by surface contamination. The non-chromate formulation addresses regulatory restrictions in many manufacturing regions.
- Broad Thermoset Resin Compatibility: Addivion RA 700 is suitable for use with epoxy, unsaturated polyester, vinyl ester, phenolic, and bismaleimide resin systems, covering both ambient-cure and elevated-temperature cure cycles. It is applicable to autoclave processing, oven-cure, resin transfer molding, hand layup, and vacuum infusion operations, supporting versatile use across diverse composite manufacturing workflows.
- 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. The isopropanol solvent carrier makes it particularly well-suited for enclosed or partially enclosed molding environments where heptane-based products would introduce greater flammability risk. In fiberglass reinforced plastic fabrication, Addivion RA 700 enables clean part release from gel-coated and non-gel-coated mold surfaces without contamination from wax or silicone residues. In epoxy composite layup and autoclave processing, the product provides stable release performance at elevated cure temperatures. Wind energy blade manufacturers use fluoropolymer release agents to achieve consistent release over extended production runs on large-format mold tools, reducing preparation time between cycles.
Addivion RA 700 is also applicable to resin transfer molding and vacuum infusion processes where the release agent must remain stable during resin injection under vacuum. Automotive composite manufacturers use the product on matched-die tools for exterior body panels, structural brackets, and underbody structural components. In marine composite fabrication, the product is applied to hull molds, deck molds, and small watercraft tooling to support clean demolding of vinyl ester and polyester resin systems. Aerospace tooling applications include carbon fiber reinforced polymer fabrication on metallic and composite mandrel tools, where contamination-free mold surfaces are critical for subsequent bonding, painting, and surface treatment steps. The higher flash point of Addivion RA 700 is a practical advantage in workshop environments with limited ventilation or strict hot-work permit requirements.

Addivion RA 700: Safety & Handling
Addivion RA 700 should be handled in accordance with applicable safety procedures for solvent-based chemical products. The isopropanol solvent carrier is classified as a flammable liquid with a flash point of approximately 12°C. All ignition sources — including open flames, sparks, hot surfaces, and static discharge — must be eliminated in areas where Addivion RA 700 is applied, stored, or transferred. Ventilation must be adequate to prevent the accumulation of solvent vapors above applicable occupational exposure limits for isopropanol. Users should wear appropriate personal protective equipment including solvent-resistant gloves, eye protection, and respiratory protection as specified in the Safety Data Sheet. Addivion RA 700 should not be used in enclosed spaces without mechanical ventilation. The higher flash point of the isopropanol carrier offers a relative flammability advantage over heptane-based alternatives, but appropriate fire prevention measures must still be maintained.
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.
