LW-8128A/LH-8116: UL 94 V-0 Crystal Clear Epoxy Potting Resin for Electronic Connectors | Hand-Pour Application
Product Overview
LW-8128A/LH-8116 is a premium two-component, crystal clear epoxy potting system engineered for hand-pour encapsulation of sensitive electronics. Featuring UL 94 V-0 flame resistance, modified PBA epoxy resin (LW-8128A), and a modified amine hardener (LH-8116), this system delivers exceptional clarity, electrical insulation, and fire safety for electronic connectors, sensors, and micro-transformers. With room-temperature curing and vacuum-compatible processing, it ensures bubble-free protection against moisture, chemicals, and thermal stress.
Key Features & Benefits
| Property | Specification | Benefit |
|---|---|---|
| Flame Resistance | UL 94 V-0 Certified | Prevents fire propagation in electrical failures. |
| Clarity | Crystal Clear (Custom Color Options) | Aesthetic transparency for visual inspection of components. |
| Curing | Room-Temperature Cure | Energy-efficient processing; no ovens required. |
| Processing | Hand-Pour or Vacuum Casting | Flexible for low-volume batches or precision vacuum impregnation. |
| Electrical Safety | High Dielectric Strength | Reliable insulation for connectors operating under electrical stress. |
| Compatibility | Pre-Mixed Fillers & Color Paste | Uniform consistency; reduces mixing errors. |
Applications
Ideal for encapsulating:
Electronic connectors (signal, power, PCB headers)
Miniature transformers and inductors
Sensor modules and LED arrays
Insulation bobbins and coil terminals
Wearable electronics and IoT devices

Processing Guide
Mixing: Blend LW-8128A resin and LH-8116 hardener at 100:22.5 pbw (default ratio). Add LC-series color paste if required.
Degassing: Vacuum degas mixture (recommended for bubble-free clarity).
Pouring: Hand-pour or gravity-cast over components.
Curing: Cure 24h at 25°C (accelerated curing at 60°C optional).
Why Choose This System?
Flame Safety: Meets stringent UL 94 V-0 standards for electronics in high-risk environments.
Ease of Use: Paste consistency simplifies manual application without sagging.
Optical Clarity: Maintains component visibility for QC inspections.
Adaptable: Integrates with existing hand-pour or vacuum production lines.
