Applications of Heloxy WC68 in Industrial Manufacturing

Heloxy WC68, a liquid aliphatic glycidyl ether, serves as a multifunctional reactive diluent within industrial epoxy formulations. Our factory supplies this material directly to large-scale formulators in coatings, composites, adhesives, electronics, and automotive sectors. We ensure supply chain transparency from synthesis through to downstream integration by global manufacturers.

1. High-Solids Epoxy Floor Coatings

Facility operators employ Heloxy WC68 to reduce viscosity and improve workability in high-solids and 100% solids epoxy formulations for industrial and commercial flooring. It allows formulators to decrease solvent content without sacrificing chemical resistance or mechanical performance. It is particularly valued in cleanrooms, pharmaceutical plants, and automotive workshops where VOC compliance is critical. Heloxy WC68 enters at the formulation stage, directly modifying the resin system before pigment, filler, and hardener addition. Floor coating manufacturers achieve improved film leveling, enhanced substrate wetting, and stable color dispersion while maintaining rapid cure profiles for heavy-duty environments.

2. Electrical Encapsulants and Potting Compounds

Heloxy WC68 is incorporated in epoxy systems for electrical potting and encapsulation to reduce resin viscosity, permitting efficient void-free filling of sensitive coil windings and electronic modules. OEMs in automotive electronics and power supply manufacturing utilize Heloxy WC68 to enable precision casting of transformer housings, connectors, and PCB assemblies. The diluent supports uniform wetting of intricate component geometries while retaining insulation resistance and thermal shock protection required in demanding service environments. Material enters the bulk mixing step, blended with base bisphenol A epoxy and flame retardants before degassing and mold casting.

• RoHS Directive 2011/65/EU – Restriction of Hazardous Substances

Typical usage ratio

• 7–18% by weight within the epoxy system, optimized for fillability, dielectric breakdown resistance, and moldability across component sizes.

Downstream process integration

• Premixed with base epoxy and additives prior to degassing operation.
• Injected or gravity-cast into prepared electronic component housings.
• Participates in thermal-curing or ambient-temperature cycles based on curing agent selection.
• Final degassing to avoid air entrapment and preserve insulation properties.

3. Structural Composite Laminate Manufacturing

Composite manufacturers employ Heloxy WC68 as a reactive diluent in epoxy infusion resins for glass, carbon, and basalt fiber laminates. Reduced viscosity ensures thorough fiber wet-out and void-free consolidation during vacuum infusion and RTM (resin transfer molding) operations, essential for marine, wind energy, and transport applications. The additive’s reactivity with the matrix maintains high crosslinking density required for structural strength and fatigue resistance. Manufacturers add Heloxy WC68 at the main resin blending phase before mixing with curing agents and promoting agents, ensuring even distribution throughout the matrix and consistent final composite properties.

Industry compliance standards

• EN 45545-2 – Fire protection on railway vehicles
• ASTM D2344 – Short-beam strength of polymer matrix composite materials
• DNVGL-ST-0376 – Structural design of wind turbine blades
• ISO 12215 – Marine structures: Hull construction and scantlings

Typical usage ratio

• 2–12% by weight of epoxy resin, adjusted for laminate thickness, fiber type, and flow rate needs. Higher concentration increases resin flow but can reduce Tg (glass transition temperature) and mechanical modulus.

Downstream process integration

• Introduced into base resin before curing agent or accelerator addition.
• Thoroughly homogenized before resin infusion or injection into laminate stack.
• Cured under vacuum and elevated temperature as per reinforcement and resin system requirements.
• Integrated QC testing for void content and mechanical strength post-cure.

4. Reactive Epoxy Adhesive Formulation

Formulators of two-component structural adhesives use Heloxy WC68 to tailor viscosity and open time for assembly line and field application, especially in construction, aerospace, and vehicle assembly sectors. The diluent is chosen to balance flow for thin bondlines and to facilitate wetting of metal and composite substrates while retaining necessary tensile shear strength and thermal stability after cure. It is blended into the resin phase, followed by filler and toughener addition, before the curing agent. Homogeneous distribution during mixing is important to ensure complete reaction and final bond durability. Systematic usage supports peel resistance and high lap shear properties required in demanding environments.

5. Marine and Protective Anticorrosion Coatings

Marine and industrial coating manufacturers employ Heloxy WC68 within epoxy systems used for heavy duty corrosion protection of steel, concrete, and aluminum structures in aggressive saltwater, chemical, and atmospheric environments. The diluent allows for high-build, low-VOC application, maintaining film integrity and adhesion under immersion and splash conditions. It enters coatings at the resin mixing stage and influences final pot life, cure speed, and application properties such as sprayability and sag resistance.
