Why PCBs in Chennai Need Conformal Coating
Chennai's hot, humid coastal climate, salty sea air and heavy north-east monsoon rains are hard on electronics. Moisture and salt cause corrosion and leakage currents on unprotected PCBs. Acrylcoat protects boards and component leads against moisture, oxidation and fungus.
What Acrylcoat protects against
- Moisture, humidity and condensation
- Oxidation and corrosion of component leads
- Fungus growth in humid conditions
- Dust and contamination between conductors
- High-voltage arcing and corona shorts

What is PCB conformal coating and why is it needed?
A conformal coating is a thin protective film applied over a printed circuit board assembly. It follows the shape of the board and components and protects them against moisture, dust, fungus, oxidation and corrosion, and against high-voltage arcing and corona shorts. This reduces field failures and extends product life.
Do you supply conformal coating to Sriperumbudur and Oragadam?
Yes. We supply manufacturers in Sriperumbudur, Oragadam, Irungattukottai, Ambattur and across the Chennai region.
Which coating suits Chennai's humid weather?
ALQ-30 or AR-30 suit general boards. For electronics exposed to coastal humidity for long periods, ALQ-60 or ALQ-100 give a thicker film.
What packing sizes are available?
Acrylcoat AR-30, ALQ-30, ALQ-60 and ALQ-100 are available in 500 ml aerosol cans and in 1, 5 and 25 litre lacquer containers. AR-60 and ARB-30 Black come in 500 ml aerosols, and SKR-70 in 1, 5 and 25 litre packs. MSDS and technical data sheets are provided on request.
