Product Description

UL 94 Flammability V-0 Fire-Resistant Epoxy Potting Resin for Electrical Transformers & Coils

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

Technical Specifications

Epoxy Resin	LW-8128A (100 pbw)
Curing Agent	LH-8116 (20-25 pbw)
Color Paste	LC Series (1 pbw, optional)
Viscosity	Paste Consistency (25°C)
Pot Life	40-60 minutes (25°C)
Cure Time	24-48 hours (25°C)
Hardness (Shore D)	≥85
Certification	UL 94 V-0 Flame Rating

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
