Clear Epoxy Potting Compound 5:1 High Hardness 80 Shore D Waterproof Insulating Resin for Motor Stator Encapsulation

Clear Epoxy Potting Compound 5:1 High Hardness 80 Shore D Waterproof Insulating Resin for Electric Motor Stator Encapsulation

HN-5508AB is a clear two-component epoxy potting compound with a 5:1 mix ratio, specially formulated for electric motor stator encapsulation, motor coil protection and winding insulation. It cures at room temperature or low temperature with low viscosity and long operation time, giving excellent fluidity and easy penetration into stator slots, coil windings and narrow clearances. The cured body is bubble-free with a smooth glossy surface and high 80 Shore D hardness, providing strong mechanical support, waterproof protection and reliable electrical insulation for motors running under vibration, humidity and thermal stress.

Key Features

• Electric motor stator application: reliable encapsulation for motor stators, generator windings, solenoid coils and electromagnetic components.
• High transparency: clear cured body allows visual inspection of windings and connections after potting.
• High hardness: rigid 80 Shore D cured body resists vibration, shock, centrifugal force and mechanical stress.
• Waterproof & moisture-proof: water absorption below 0.03% (25℃*24h) protects windings from humidity and condensation.
• Excellent insulation: dielectric strength 20-22 kV/mm with high surface and volume resistance for motor winding insulation.
• Wide temperature range: stable performance from -30℃ to 130-150℃, matching motor operating and heat-rise conditions.
• Acid & alkali resistance: cured material resists chemical corrosion, moisture and air aging in industrial environments.
• ROHS & SGS compliant: meets environmental requirements for motor and electronics industries.
