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

Q2: Is it one-part or two-part, and what are the cure options?
A2: It is a two-part (two-component) epoxy with a 5:1 mix ratio by weight. It can be cured at room temperature in 12-16 hours (tack-free in 6-8 hours), or accelerated at 60-80°C in 1.5-2 hours.

Q3: What are the hardness and electrical insulation properties?
A3: Cured hardness is Shore D 85-95 for rigid protection, with a dielectric strength of 20-22 kV/mm and volume resistivity of 1.1 x 10¹⁵ ohm.cm for reliable electrical insulation.

Q4: What is its temperature and environmental performance?
A4: It withstands -30°C and a heat distortion temperature of 130-150°C, and provides acid/alkali resistance, moisture proofing and aging resistance for harsh environments.

Q5: Can I request samples, and what are the MOQ, packaging and delivery time?
A5: Yes, samples are available. MOQ is 1 kg, supplied in 30 kg/set kits (25 kg A + 5 kg B). Samples ship in 3-5 working days and bulk orders in 7-15 days, with bulk supply and factory-direct pricing.
