Low Viscosity 2:1 Mix Ratio Transparent Epoxy Potting Compound AB Glue for Electronic Encapsulation

Clear Epoxy Potting Compound 2:1 Self-Leveling Low Viscosity AB Glue for Narrow Gap Electronic Component Encapsulation

HN-5506A/B is a clear two-component epoxy potting compound with a 2:1 mix ratio, specially formulated for narrow gap and fine clearance encapsulation of electronic components. After mixing it exhibits excellent flowability and low viscosity, allowing it to easily penetrate into the minute gaps between components, coils and PCB traces before curing into a rigid, crystal-clear protective layer with high hardness and outstanding electrical insulation.

Key Features

• Low viscosity & excellent flowability: penetrates narrow gaps, fine clearances and dense component layouts without voids.
• 2:1 two-component system: simple mix ratio and self-leveling flow compatible with automatic dispensing lines.
• High transparency: crystal-clear cured body enables visual inspection of components and wire bonds after potting.
• High hardness: rigid 70-75 Shore D cured layer protects precision components against vibration and shock.
• Excellent insulation: prevents current leakage and short circuits in high-voltage and precision electronics.
• Anti-yellowing: maintains transparency under prolonged light exposure for LED modules and display applications.
• Wide temperature range: stable physical and electrical properties from -40℃ to 120℃.
• Moisture-proof & tamper-proof: seals modules against humidity while providing confidentiality protection.
• ROHS & SGS compliant: meets environmental requirements for electronics industries.

Technical Parameters

Applications

Narrow-gap electronic modules, transformers, LED modules and lighting fixtures, indicator-light components, aquarium pumps, high-voltage components, precision sensors, relays, confidentiality modules and other precision electronic devices requiring transparent high-hardness encapsulation with deep gap penetration.

FAQ

Q1: What is HN-5506A/B and what is it designed for?
A1: HN-5506A/B is a two-component, high-transparency epoxy crystal glue (Epoxy Potting Compound) with high hardness, low viscosity, excellent self-levelling and defoaming. It cures to a crystal-clear, UV-resistant and anti-yellowing body, ideal for narrow-gap encapsulation of electronic components, LED lighting, display modules, river tabletops and crystal craft.

Q2: What is the mix ratio, pot life and curing schedule?
A2: Mix Component A and Component B at a 3:1 ratio by weight. Pot life is 20-30 minutes at 25°C (150 g mix). Initial cure is 6-8 hours and full cure 12-16 hours at 25°C, or a heat-accelerated cure in 1 hour at 80°C (room-temperature pre-cure recommended). One-time pouring of up to 3-5 cm thickness at 25°C is supported with built-in defoaming.

Q3: What are the cured mechanical, electrical and thermal properties?
A3: Cured hardness is Shore D 78-83; dielectric strength is 25 kV/mm; volume resistivity is 4.3 x 10¹⁵ ohm.cm and surface resistivity 2.6 x 10¹⁴ ohm; the glass transition temperature (Tg) is above 90°C and temperature resistance is -60°C to 135°C, with excellent adhesion and low cure shrinkage.

Q4: How should it be mixed, degassed and poured?
A4: Stir Component A thoroughly before use (warm to 60-80°C if crystallised), weigh A and B at 3:1 by weight, mix thoroughly scraping the container walls and bottom, optionally vacuum-degas for high clarity, then pour into the clean, dry mould or device within the pot life. Do not move or stress the part during cure.

Q5: What are the packaging, storage and shelf life, and do you offer customization?
A5: Supplied as Component A 15 kg plastic drum plus Component B 5 kg plastic drum (custom kits available). Store sealed at 5-25°C away from sunlight and moisture; shelf life is 12 months. Classified as non-dangerous goods for transport. Custom OEM/ODM formulation is supported - contact us for free samples.
