Specifications

Key Applications & Uses

• Hardened gears and gear components – Provides outstanding edge preservation for accurate evaluation of case hardening, surface treatments, and wear patterns.
• Hard alloys (e.g., tool steels, tungsten carbide, superalloys) – Ensures minimal rounding or damage at interfaces during preparation of high-hardness materials.
• Ceramics and advanced technical ceramics – Delivers reliable mounting support for brittle materials prone to chipping or edge degradation.
• Coatings and surface layers – Ideal for analyzing hard coatings, PVD/CVD layers, and heat-treated surfaces where edge integrity is critical.
• Metallographic and failure analysis in aerospace, automotive, tooling, and R&D labs requiring precise edge examination under optical or electron microscopy.

Why Choose from G-Hexa?

• Superior Edge Retention – Glass fiber reinforcement combined with high Shore D hardness (90-93) minimizes abrasion differential, prevents edge rounding, and protects delicate features better than standard phenolic or unfilled resins.
• Excellent Adhesion & Low Shrinkage – Strong physical bonding to sample surfaces eliminates gaps, reduces pull-out artifacts, and ensures void-free mounts even on irregular or porous specimens.
• Optimized Processing – Fast cycle times (5-7 min holding, 4-6 min cooling) and compatible parameters (150-180 °C, 150-300 bar) suit most standard hot mounting presses for efficient lab throughput.
• Premium Quality & Consistency – Manufactured to exacting standards for reliable, repeatable results in demanding research, quality control, and production environments.
• Trusted by Labs Worldwide – G-Hexa delivers lab-proven performance for universities, pharmaceutical/biotech, industrial QA, and materials science facilities seeking durable, artifact-free mounts.
• Flexible Packaging – Available in convenient 1 kg, 4 kg, and bulk 20 kg sizes to match your usage volume and minimize waste.

Frequently Asked Questions (FAQs)

What makes GHEXA-MNT-CON-EPO-004 ideal for edge-critical samples? Its glass fiber-filled epoxy formulation provides extremely high hardness and superior adhesion, resulting in minimal shrinkage and exceptional edge bonding—critical for preventing rounding or damage during grinding/polishing of hard materials.

Which mounting press settings are recommended? Use 150-180 °C heating temperature, 150-300 bar pressure, 5-7 minutes holding time, and 4-6 minutes medium-rate cooling. Always follow your press manufacturer’s guidelines and adjust slightly based on sample size.

Is this resin suitable for vacuum impregnation? No, this is a hot (compression) mounting resin designed for press use. For cold mounting or vacuum impregnation, consider our epoxy castable systems.

How does it compare to phenolic resins? GHEXA-MNT-CON-EPO-004 offers better edge retention, lower shrinkage, higher hardness, and stronger adhesion than phenolic alternatives, making it superior for hard alloys, ceramics, and precision edge analysis—though phenolics may suffice for routine softer samples.

What package sizes are available?

• 1 kg (ideal for small labs or testing)
• 4 kg (standard lab volume)
• 20 kg (bulk for high-throughput facilities)

Can it be used with heat-sensitive samples? The 150-180 °C range suits most metallic and ceramic samples, but for very heat-sensitive materials, evaluate cold-mounting epoxies or lower-temperature alternatives.

How should the resin be stored? Store in a cool, dry place away from moisture and direct sunlight to maintain optimal flow and curing properties. Shelf life is typically 12-24 months under proper conditions.
