Customized Black Epoxy Potting Compound 5:1 for LED Driver Electronics Encapsulation

HANAST HN-5508 A/B Customized Black Epoxy Potting Compound 5:1 for LED Driver & Electronics Encapsulation

HN-5508 A/B is a customizable two-component black epoxy potting compound developed for the electronics industry. Mixed at a 5:1 ratio by weight, it flows with low viscosity and long pot life, penetrates narrow gaps, and cures into a smooth, glossy, high-hardness (Shore D 85-95) black encapsulant with high dielectric strength. It is widely chosen for LED drivers, power supplies and general electronic encapsulation, and is available with custom OEM/ODM and private-label formulation to match your exact requirements.

Key Features

• Customized formulation: OEM/ODM and private-label options for colour, viscosity, pot life, hardness and cure speed

FAQ

Q1: What is HN-5508 A/B and which applications does it suit?
A1: HN-5508 A/B is a 5:1 two-component black epoxy potting compound with Shore D 85-95 hardness and high dielectric strength, widely used for LED drivers, power supplies, transformers, resistors, filters, sensors and circuit boards.

Q2: Can HN-5508 A/B be customized or supplied as a private label?
A2: Yes. We provide custom OEM/ODM and private-label formulation of colour, viscosity, pot life, hardness and cure speed, so the product can be tailored to your LED driver or electronics program and branded as required.

Q3: What are the mix ratio and curing schedule?
A3: Mix Component A and Component B at a 5:1 ratio by weight. Pot life is 2-3 hours at 25°C (100 g mix); it is tack-free in 6-8 hours and fully cured in 12-16 hours at 25°C, or in 1.5-2 hours at 60-80°C.

Q4: What are the hardness and electrical insulation properties?
A4: Cured hardness is Shore D 85-95, with a dielectric strength of 20-22 kV/mm and volume resistivity of 1.1 x 10¹⁵ ohm.cm, and it withstands -30°C to a heat distortion temperature of 130-150°C.

Q5: What are the MOQ, packaging, wholesale price and delivery time?
A5: MOQ is 1 kg, supplied in 30 kg/set kits (25 kg A + 5 kg B), with bulk wholesale pricing and private-label options. Samples ship in 3-5 working days and bulk orders in 7-15 days.
