Product description

MDCOAT 7060 is a low viscosity one component silicone resin protective coating, easy to use, after curing to form a layer of optical transparent film, with excellent high and low temperature resistance, weather resistance, electrical insulation properties and excellent waterproof, seismic and absorption expansion and contraction, corona resistance, leakage resistance. It can enhance the moisture-proof and anti-fouling ability of electronic circuits and components, prevent the solder joints and conductors from being eroded, and also play the role of shielding and eliminating electromagnetic interference, preventing short circuit, and improving the insulation performance of the circuit board. In addition, the coating protective film is also conducive to the friction resistance and solvent resistance of the line and components, and can release the pressure caused by periodic changes in temperature.

How to use

Application process

Surface treatment: Before coating, dust, moisture (moisture) and oil should be removed from the surface of the object to be coated and kept dry.
Cover: If some connectors, sockets, switches, inserts and other areas are not allowed to have coating materials. Appropriate covering measures should be taken.
Construction: According to the complexity of PCB, device distribution density and configuration can be used brush coating, spray, dip coating and other different methods of construction. For a small amount of spraying, manual spray gun can be used, automatic spraying, and 100% paint can be used directly. The amount of spray pressure will depend on the specific type of spray equipment used, and the effect goal is that the coating does not hang and does not leak. The thickness of a coating film is generally between 0.1-0.4mm, if you want to get a thicker coating, it is best to get by applying two layers of thinner coating, and it is required that the first layer must be completely dried before being allowed to apply the second layer.
Curing: Flat on the support after construction, can be cured at room temperature. Heating can speed up the curing speed, the recommended heating temperature of 50℃ -60 ℃ 5-10 mins.

Room temperature curing: 7060 coating is cured at room temperature by reacting with water vapor. The coating of 0.1mm will reach surface drying in about 10min, and it will take 72 hours to cure completely. The recommended curing conditions are 25℃ and at least 50% relative humidity, and increasing the temperature and humidity can speed up the curing speed.
Heating curing: heating can shorten the surface drying time of the product. Generally 0.1mm thick coating needs to volatilize at room temperature for 10min. If the coating has fish eyes or contains air bubbles, allow more time for the glue to level out before heating up. Boards coated with 9060 should be stored at room temperature for at least 72 hours before low temperature testing.
Repair: Repair an already coated component by simply touching the soldering iron directly to the coating to remove the component. Then install a new component, and clean the area with a brush or solvent; It can also be cleaned with solvent; And reapply with paint after drying.
