Basic concept of spray coating for three defense

Time:2017-12-14Browse:2246Second

The spray coating is coated on the surface of the circuit board, forming a thin film of only 40-60 microns thick, light and flexible. It can protect the circuit from damage, such as chemical substances (such as fuel, coolant, etc.), vibration, moisture, salt spray, humidity and high temperature. Under these conditions, the circuit board may be corroded, the mold growth and the short circuit are produced, which leads to the failure of the circuit without the use of the triple defense adhesive. The protective film formed by three anti glue can effectively isolate and protect the circuit from erosion of chemicals, dampness and other contaminants, thereby improving the reliability of circuit boards, increasing its safety factor and ensuring its service life. Three spraying glue glue spraying three three characteristics of the silicone adhesive is a single component, low viscosity silicone resin. It is convenient to use, can be brushed or impregnated, and has good adhesion to various circuit boards. With good temperature resistance (-60 at -200 DEG C) within the scope of heat aging performance good; the solidified to form a layer of transparent, elastic and glossy protective film has excellent dielectric properties, water resistance, shock resistance, weather resistance, contamination resistance, UV resistance, and moisture insulation performance. Three adhesive has highlighted "moisture", "anti salt fog", "insulating" performance; in the humid environment of the film will not lose its good dielectric properties; strong oxidation resistance, ageing resistance, corrosion resistance of different concentrations of acid, alkali, salt, at room temperature or low temperature curing film, compact and bright, no cracks, and decorative. The three protection spray adhesive is widely used for flexible (rigid) circuit boards, aviation instruments, computer control panels, industrial control panels, semiconductor crystal line protection, home appliances controller, electronic components and protective coatings for various circuits.The spray coating is coated on the surface of the circuit board, forming a thin film of only 40-60 microns thick, light and flexible.
