Product Description
INTRODUCTION
Conformal coating is a specially formulated coating used to protect circuit boards and related equipment from environmental erosion, thereby improving and extending their service life and ensuring the safety and reliability of use. Conformal coating has good high temperature resistance; after curing, it forms a transparent protective film, which has excellent insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, anti-corrosion, anti-aging, corona resistance and other properties.
Conformal coatings are used in high-tech fields, electronics industry, military industry, wiring lines, etc. Conformal coatings can enable manufacturers to improve product quality and reduce expensive protection period failure costs.

|
|
KEWEI-70 is a kind of single-component acrylic transparent protecting paint, which can form a glazing and stretchable protecting foam on various of printed circuit boards. It can prevent the corrosion of weak acid, alkali, alcohol, mildew, salt fog, thermal stress, ultraviolet radiation, humidity and insect. This product is high-temperature resistant and will not drop on heat, and tin can be welded directly on the protecting foam. It can conform to the requirements of EU ROHS Directive completely.

INSTRUCTIONS
Brushing
The brushing area should be larger than the area occupied by the device to ensure full coverage of the device and pad. Lay the board flat when brushing. There should be no drips after brushing, and the brushing should be smooth, and there should be no bare leaks, and it should be placed on the bracket after brushing.
Dipping
Put the diluted paint into the immersion bucket. The circuit board components should be immersed in the paint tank vertically. The connectors should not be immersed unless they are carefully covered. The circuit board or components should not be immersed too fast to avoid air bubbles.
spraying
Adjust the spray gun and pressure, and put the diluted paint into the watering can. The nozzle of the spray gun needs to be sprayed smoothly. In order to ensure that the paint can pass through the bottom of the component well, the spray should be sprayed smoothly from all angles.
