NX-203 Copper Conductive Coating Introduction

 

NX-203 conductive coating designed by Shenzhen NanXiang Technology Co., Ltd is with low price and good performance. After sprayed inside housing of electronic products, conductive silver coated copper power forms dense conductive layer film after drying conductive paint film. The dense conductive layer film has functions of good shielding electromagnetic radiation, anti-electromagnetic interference and anti-static. It also has good conductive performance in application of composite materials. NX-203 is cost effective, with low price, large spray area and simple friendly operation. Nowadays, NX-203 is widely applied in inside housing of various electronic products like GPS, DVD, DVB, medial equipments, etc.

 

1. Basic Parameters:

 

Product Name Copper conductive coating
Model NX-203
Packing specs 5Kg/pot; 10Kg/pot; 20Kg/pot
Color Copper red
Viscosity Thixotrophic mixture
Solid content 25
Theoretical coverage rate 5-8 square /kg (conductive paint film thickness=20microns)

 


2. Technical Parameters:

 

Conductive paint application parameters less than 1 ohm /20 micron thickness / distance 10cm
Suggested conductive paint film thickness 15-25 micron (ASTM D4138-94)

 


3. User Guidelines:

 

1) Paint Mixing:

Diluted by butyl acetate, additive amount of 30%-50% (i.e.1:0.3-0.5) by weight ratio of conductive paint.

2) Spraying and tools:

Side pot or a pot of paint spray gun can be used. Caliber is generally 0.3-2.0mm. Small items are suggested to use about 0.5mm diameter spray gun, and bulky items use 1.5-2.0 diameter spray gun.

 

Generally distance of spray gun and spray products should be 100-150mm and not above 200mm. Spray should be uniform and the film thickness should be more than 15 microns to achieve good electrical performance.

 

3) Use materials:

ABS, HIIPS, PS, PC and other plastic parts, and other composite materials or metal materials, but it must be not smooth surface. (Another suitable conductive paint will be developed if it is used for special materials.)

 

4) Drying Conditions:

Dry time is 15 minutes; drying time is 30 minutes at 65 degree bake.

Air dry time is more than 4 hours.


5)  Test Conditions:

Test should be done after sprayed conductive paint film has completed cooled and dried.

 

Note:

 

■ Make sure to use side port or a pot spray gun to spray conductive paint.

■ Small items are suggested to use K-3 spray gun and large items use W-71 spray gun.

■ Conductive paint should be stirred fully and well in pot before use, and then it could be diluted.

If stirring fully and evenly, metal particles are dispersed evenly to make sprayed conductive paint film achieve best conductivity.

■ It is better to stir frequently and stirring frequency should be less than 5 minutes to achieve best performance.

■ Conductive paint should be used as soon as possible to avoid long term storage after opening.

■ Due to easy precipitation of metal power, its performance will not be affected after stirring.

■ Protective measures: During using conductive paints, please ensure operating environment is well ventilated and avoid prolonged direct contact or inhalation. Not allowed to pour conductive paint into drains or sewers to pollute environment.

■ Storage: conductive paints are sealed and stored in ventilated and dry indoor environment.

■ Shelf Life: 6 months at 25 ℃ (intact)
