Dolphon ER-41 red polyurethane insulating varnish

Product Description:

Red varnish, air drying, electrical insulating coating, and modified alkyd resin as the base material.

Performance:

Fast wind (self) drying and coloured varnish have good adhesion to metal and polymer materials. Providing additional protection to the external impact,

Especially resistance to humidity. It also has good stability in weatherability, mould resistance and seawater. It is compatible with all the generic lacquer lines.

Product application:

The interior painting and transformer coating are the classic applications of this resin. In addition, it has wide applications in electrical and electrical fields.

The motor housing, excitation coil, electromagnetic coil, busbar, junction box, collector ring, collector connector, control coil and circuit board.

standard

F (155 degree C) level in the UL- system

Conforming to RoHS- 2011/65/ EC

Color: red (Ban Yaguang)

Specification: 5 gallons

Origin: the United States

Condition of placement

This product can be placed in a closed container for 12 months (maximum 30 degrees C) at room temperature.

The varnish should be placed in a stable environment, avoiding sunlight and ultraviolet radiation, and avoiding heat source.

Usage method：

When spraying, it is necessary to mix the diluent T-200 with the suitable processing viscosity in the usual manual nozzle.

When impregnating, it can be allocated to the proper viscosity with diluent T-200. In order to prevent dry air from contacting with air for a long time,

A nitrogen gas layer should be used to protect the surface of the impregnated pool. We should pay attention to the regulations of the safety regulations and the relevant departments.

Curing should be carried out under explosion protected environment, and exhaust fans should be equipped under environmental conditions.

25 degrees C, air drying time: 0,5 hours, no dust.

2 hours force pressing no adhesion

48 hours completely dry

The working equipment should be cleaned with the solvent T-200 as soon as possible. The maintenance of coating equipment, especially cleaning, should be carried out according to operation requirements.
