Epoxy electronic potting

[Features] ● This black room temperature curing epoxy potting, low viscosity, good fluidity, easy to penetrate into the gap; ● can be room temperature or moderate temperature curing, curing speed; ● no bubbles after curing, surface smooth, good gloss, high hardness; ● cured flame-retardant properties, good acid and alkali resistance, water and oil proof and dustproof performance, good resistance to heat and atmospheric aging; ● cured with good insulation, compression the adhesive strength of higher electrical and physical properties. The scope of application ● who require infusion sealing, packaging protection, insulation or other proof of electronic products can be used; ● widely used in transformers, AC capacitor, ignition coil, negative ion generator, aquarium water pumps, ignition coils, power modules , electronic controllers and other electronic components; ● does not apply to flexible or soft shell encapsulating products.
