PCB Lacquer or post flux was developed to prevent surface oxidation of copper pad and other contamination. High reliability resin used provides high oxidation prevention and fast drying.
 
KTE PCB lacquers have the following excellent features: 

• It forms a clear thin non porous film on the printed circuit boards.
• Thin film is resistant to heat and does not impede solder ability.
• Faster drying. Thus it has superior handling and storage properties.
• It is resistant to hydrolysis and impervious to water vapour.
• Totally non corrosive. Can preserve the PCB long under normal storage conditions.
