Water Clear Non Yellowing UV Resistant Optical Epoxy for LED Display Lamination and Clear Epoxy Potting Compound

HN-5506A/B is a two-component high-transparency epoxy crystal glue developed for optical and display applications. Its low viscosity, self-levelling flow and built-in defoaming give a water-clear, bubble-free surface that reproduces fine detail in display modules, digital tubes and photo coatings. After curing it forms a high-hardness, non-yellowing material with excellent adhesion, low cure shrinkage, moisture, water, oil and dust protection, and resistance to weathering and UV yellowing. One-time pours of 3-5 cm are possible at 25 °C, and the cured surface can be sanded and polished.

• Water-clear, high-transparency cured appearance for optical display applications

• High hardness Shore D 78-83 with low cure shrinkage
• Low viscosity 800-1400 mPa·s, good flowability and self-levelling
• Built-in defoaming for bubble-free optical surfaces
• Moisture-proof, waterproof, oil-proof and dust-proof
• High dielectric strength 25 kV/mm, volume resistivity 4.3 × 10¹⁵ Ω·cm
• Glass transition temperature above 90 °C and temperature resistance -60 to 135 °C
• Supports one-time pouring of 3-5 cm thickness at 25 °C
• Cured surface can be sanded and polished; RoHS compliant

• Display and optical: LED display module lamination and packaging, digital tubes, display windows, photo surface coating and light guide components
• Signage and doming: LED signage, resin luminous characters, light boxes, label doming, crystal doming and badge doming
• Lighting: LED lighting fixtures, outdoor lighting, underwater lights and aquarium lighting
• Electronics: encapsulation, bonding and sealing of electronic products, power modules, PCB assemblies and high-voltage insulation parts
• Decorative and craft: river tabletops, large transparent castings, crystal craft moulding, resin art and DIY handicrafts

All values are measured at 25 °C after the recommended cure schedule and are for reference only.

1. Pre-mix: Stir Component A thoroughly before use. If crystallisation occurs under extreme cold, warm at 60-80 °C until fully dissolved.
2. Weighing: Accurately weigh A and B at 3:1 by weight using a precision electronic scale.
3. Mixing: Mix thoroughly until uniform and scrape the container walls and bottom.
4. Degassing: For high-clarity optical parts, degas under vacuum to remove entrapped air. Built-in defoaming also releases air without vacuum for general work.
5. Pouring: Pour into the clean, dry mould or device within the 20-30 minute pot life. One-time pouring up to 3-5 cm thickness is supported.
6. Curing: Cure at 25 °C for 12-16 hours, or at 80 °C for 1 hour. Do not move or stress the part during cure.

• Component A: 15 kg plastic drum; Component B: 5 kg plastic drum; custom kit sizes available
• Store sealed in a cool, dry, well-ventilated area at 5-25 °C, away from direct sunlight and moisture
• Shelf life: 12 months from the date of manufacture under recommended storage
• Transport: non-dangerous goods (general chemicals)
