Products Details


(Conformal Coating) It is a new generation Conformal Coating specially formulated to provide instantaneous clear, dry protective coating to Printed Circuit Boards etc. The micron thickness layer of SPRAY – 329 protects the PCB from dirt, dust, moisture, mild chemical fumes, pollution etc. It also protects tracking and prevents non-intentional circuit connections due to dirt or dust. SPRAY – 329 can be a soldered through without fear of highly toxic gases being produced and hence repairs or maintenance activities can be carried out even after the application of the coating. Ease of inspection is further enhanced because of fluoresces under UV light thereby offering on – line inspection enabling faster production cycle.


Protection of Printed Circuit Boards


-    Quick Drying, hard, flexible, non-conductive coating.
-    Clear coating allows easy visual inspection of the circuit board.
-    Protects the circuitry from hazards such as vibration, moisture, chemical fumes, fuels, humidity, high temperature etc. which lead to corrosion and current leakage resulting in
-    board failure of an uncoated PCB.
-    Solder through coating for easier maintenance in subsequent stages.
-    Allows higher power and closer track spacing as it prevents current leakage which aids in miniaturization.
