Three paint from the chemical composition can be divided into acrylic, silicone, polyurethane conformal coating; And from the Cure, solvent type curing, room temperature curing, thermal curing and UV curing. They generally by the product selection process viscosity (at different concentrations with different solid content) determined. All three paint manufacturers generally have their own configuration diluent to dilute the concentration of different products to determine the appropriate spray, brush, dip different process requirements. 1, three anti-solvent-containing acrylic resin paint (currently on the market the most widely popular product) Features: Table dry, fast curing time, a good three anti-sex, cheap, color, transparency, texture, flexibility, features with easy-to-repair . For example Suzhou Vertex's acrylic conformal coating VT-380, the three anti-paint is a specially formulated coating to protect circuit boards and related equipment from the erosion of a bad environment to improve and extend their service life ensure the safety and reliability. Under realistic conditions, such as chemical environment (fuel, cooling, etc.), vibration, high dust, salt fog, humidity and high temperature, circuit boards may cause corrosion, softening, deformation, mildew and other issues, leading to circuit board failure . Three anti-paint coated on the outer board is formed of light and flexible layer, a thickness of about 25-50 microns thick film. It can be from damage under these harsh conditions protection circuit. 2, solvent-free acrylic resin conformal coating characteristics: UV curing, in a few seconds to ten seconds is dry, color transparent, hard, anti-chemical corrosion and wear resistance is also very good. UV curing to the initial three anti-paint, without the use of solvents. They do not burn, does not contain volatile organic compounds, in full compliance with existing and proposed environmental regulations. They can provide good chemical resistance and heat resistance, good flexibility, surface gloss, strong adhesion, good coverage. When asked short curing, is a fraction of other products (in seconds.), By improving productivity while greatly reducing the cost of the product. For example Suzhou Topan's UV glue VT-3622, dispensing and bonding for thermoplastic materials, such as PMMA (acrylic, plexiglass), PC, ABS, PS,, PVC, PCB and so most of the engineering and adhesive can be used for plastic and glass, plastic and organic materials such as metals, plastics typically used for fixing the circuit board, the phone keys dispensing industry. 3, polyurethane conformal coating characteristics: brittle texture, excellent solvent resistance. In addition to superior moisture-proof performance, and stable performance at low temperatures. Companies such as Suzhou TOPAN polyurethane conformal coating QT-4568, as the heat transfer media, has excellent electrical insulation and thermal conductivity, high temperature resistance, long-term work in the temperature range of -60 ° ~ 250 ° without there will be wind cirrhosis or melting phenomenon. The silicone-based products, combined with high thermal conductivity fillers, non-toxic, tasteless, non-corrosive, stable chemical and physical properties. 4, silicone conformal coating soft elastic coating material can be a good release pressure, high temperature of 200 degrees, and easy to repair. There are silicone conformal coating solvent-based and solvent-based clear two products. They doors for high temperature conditions, with good chemical resistance and salt spray characteristics. Although the solvent-based products can be defended by the access operation, but it is difficult to be clear organic solvents. Their biggest feature is as time goes on, more and more strong chemical bond. For optimum performance, if desired, can be heat-cured. Electrical insulating properties of silicone-based products have significant, making it apply to high-power and high integration circuit board ideal product. For example Suzhou Topan's silicone conformal coating VT-381, has excellent waterproof, moisture, dust, corrosion, aging and other characteristics, widely used in circuit boards, insulation protection of electronic components.
