Epoxy Potting Compounds, 5508
JF-5508W White Low Viscosity Epoxy Resin
JF-5508W Black Low Viscosity Epoxy Resin
Two-component epoxy resin is an environmentally friendly epoxy resin potting adhesive that can cure at room temperature or with heating. Fully compliant with the EU ROHS directive and SVHC-REACH requirements, it has low viscosity, a long working time, good flowability, and can easily penetrate into gaps in products. After curing, it features no bubble, a smooth surface, good gloss, high hardness, excellent acid and alkali resistance, moisture-proofing, waterproofing, oil resistance, and dust resistance, as well as resistance to humidity, heat, and atmospheric aging. This potting compound possesses excellent electrical and physical properties such as insulation, compression resistance, and high bonding strength. It can be used for potting, sealing, and encapsulation protecting electronic or other products that require insulation, moisture-proofing, and sealing.
Application
This epoxy resin widely used in transformers, resistors, sensors, thermostats, ignition coils, high-voltage packs, aquarium equipment, negative ion generators, ultrasonic atomizers, as well as electronic and electrical components that require insulation, flame resistance, and temperature resistance. Its main functions include flame-retardant insulation, sealing bonding, moisture-proofing, shock resistance, and temperature durability.
