UL Certified Excellent Insulation Properties, Fast Curing Epoxy Resin Powder Coating
◎ Introduction
This product is one kind of thermoset pure epoxy powder coating based on epoxy polyester and epoxy curing agent.
Electrical insulation can be provided by materials that facilitate the electric isolation of two parts at different voltages. Electrical insulation coatings are also known as dielectric coatings. An epoxy powder coating has insulation properties that make it effective as a high dielectric insulator on copper or aluminum conductors.
Our epoxy insulation powder coating E-RD4962-S7 can offer high dielectric strength while creating durable insulation, impervious to most elements, and allows for closer busbar location in a system ideal for single conductors or multiple conductor assemblies that may have numerous forms.
Our insulation powder coating has excellent corner coverage, which can prevent the coating film from being broken down by current from the edge and corner, so as to achieve long-term excellent insulation performance.
◎ Field of Application
This series of products are mainly used in the field of electrical insulation and can be applied to the coating of electrical components and metal substrates, which has a high demand for insulation, such as aluminum busbars, copper busbars, motor stators, rotors, transformer, magnet wire, switchboards, etc.
◎ Basic Features
Excellent electrical insulation property.
Excellent physical and mechanical property.
Good coverage ability of corner.
High-density film.
Fast curing. The curing reaction speed can also be adjusted flexibly according to customers’ demands to meet different spraying requirements.
Without weather resistance and can not be directly used outside.
Not includes a solvent and other volatile, environmental-friendly.
