B-80740 Metallic copper anti-electromagnetic wave screen open coating is a kind of anti-electromagnetic interference made of excellent conductive copper particles. It will have good conductivity when spraying only a thin layer of B-80740. performance. The resulting anti-electromagnetic interference screen has a very strong opening performance, and can provide convenience for various materials plating processes, and reduce various complicated pre-plating treatments. It can be directly electroplated by spraying (brushing) the electroplated interlayer coating, which has high production efficiency and cost saving (such as plastic plating, silica gel plating, wax handicraft plating, etc.).

Stirring and dilution:

          Shake well with a shaker Jiang B-80740 before use. The dilution ratio is paint: dilution = 1:0.5-0.8 (volume ratio)

Spraying method:

          It is possible to spray B-80740 with a conventional air pressure spraying device with a screw agitator. In the sample stage, the simplest oil can spray gun is also possible, but the B-80740 must be evenly mixed.

          Pay attention to the fact that there is no dry spray when spraying, that is, the sprayed surface should be wet and moist and even when it is sprayed, so that it has the best adhesion and conductivity. Dry naturally for 4 hours, you can fall

Brushing method:

          When the temperature is greater than or greater than 25 ° C, the sunlight is dried for 30 minutes or more, and evenly coated on the workpiece with a fine brush, and good performance can be obtained.

Used for electroplating:

          After drying or before sinking, use a digital resistor (or square meter) to measure the resistance value: it must be measured at 10 ohms from the energized rod to the power-on port.
