B-905 graphite conductive coating is an honor product in Xinshengfeng's conductive coating series. It can provide long-lasting anti-electromagnetic interference capability for electronic products, has excellent conductivity and is very stable in nature.

Product nature:

Conductive material: graphite

Binder: Acrylic plastic (when the original barrel comes)

Solid content (%): 59.5

Thinner (open oil): BL-333

Theoretical coverage area: 5m2/kg

   Volume of solid components (%): 33.3

Best shelf life: original cans for up to 6 months

Volatile ingredient: about 430g/kg

Conductive properties: <50Ω/cm2/20μm

       Standard packaging: net weight 4 kg

    Quality of spraying: The conductivity of the sprayed film is the main quality indicator of this product. When measuring, the film must be completely dried. A digital liquid crystal display resistance meter should be used, which helps to obtain more accurate data and is beneficial to quality control.

Product nature:

       Smooth spray surface, easy to mix and mix

       It is stable in temperature difference cycle test and high temperature humid environment test (temperature difference cycle test is -40 ° C to 71 ° C high temperature humid environment test is 49 ° C and humidity 95% humidity environment)

       Abrasion resistance (resistance value 祗 will increase slightly)

       Easy to operate, naturally dry

       Can add + spray decorative coating on B-905 coating without affecting its ability to prevent electromagnetic wave drying and affecting the performance of this decorative coating

       Low cost and low cost of spraying

       Matches with general plastics on the market, no spoiler

       Stable in nature, each batch maintains a consistent level

       Standard packaging: net weight 4 kg

       The quality of the spray: the conductivity of the spray film is the main quality indicator of the product. When measuring, the spray film must be completely dried. The digital liquid crystal display resistance meter should be used, which helps to obtain more accurate data. Conducive to quality control.

Stirring and dilution:

       Shake this B-905 with a shaker before use. For dilution, please dilute it by 1:05 (volume ratio)

Spraying method:

       The B-905 can be sprayed with a conventional air pressure spraying device with a propeller stirrer. In the sample stage, the single B-901 with the simplest oil-type hand spray gun must be evenly mixed. In order to protect the electronic product to which the spraypiece belongs, there is sufficient anti-interference ability, and the thickness of the spray should also be sufficient, for example, to have a dry film thickness of 20 to 25 μm. On the other hand, it should be noted that there should be no dry spray when spraying, that is, the sprayed surface should be moist and even when it is just sprayed. This gives the best adhesion and conductivity.

       The conductivity of the sprayed film is the main quality indicator of this product. When measuring, the sprayed film must be completely dried. A digital, liquid crystal display resistance meter should be used, which helps to obtain more accurate data and is beneficial to quality control.

       The surface of the spray must be clean and dry.

Dry solid:

      The dry speed of B-905 is very fast. In the work room with air conditioning and dehumidification, it can be touched by hand in about 5 minutes and baked at 130 °C for 30 minutes.
