Pure Electrostatic Epoxy Powder Coating
Product Description
Introduction
This product is one kind of thermoset pure epoxy powder coating based on epoxy polyester and curing agent.
The epoxy powder coating has insulation properties that make it effective as a high dielectric insulator on copper or aluminum conductors.
Our epoxy powder coating 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 and outstanding levelling property, 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 with smooth surface.
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.

Specifications
| Application Craft |
Spraying Method: Electrostatic spraying or fluidized bed dipping. |
| Film Thickness: It is determined according to the actual application of the customer, and the recommended film thickness range is controlled within 200 ~ 500um. |
| Substrate Preheating Temperature: 190-200ºC/10~25min (adjusted according to the thickness, size and film thickness of the workpiece). |
| Curing Condition: 200ºC/10-20min (actual temperature of workpiece surface). |
| Precautions |
This product is not recommended for outdoor use. |
| Different spray thickness will affect color, gloss, appearance and physical and chemical properties. |
| There is a difference between the laboratory sample and the production line coated board, and the customer needs to adjust the spraying parameters to meet the requirements. |
