Why PCBs in Kolkata Need Conformal Coating
Kolkata's hot, very humid climate and long monsoon season make moisture the biggest threat to electronics. Fungus, corrosion and leakage currents are common on unprotected boards. Acrylcoat protects PCB assemblies against moisture, oxidation and fungus in extremely humid conditions.
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

How to Apply Acrylcoat Conformal Coating
- Clean the boardRemove flux, oil and dust with Elclean Liquid or ELCLEAN E-Clean.
- Pre-heatWarm the PCB to about 45–50°C in an oven or with a hot-air blower to drive off moisture.
- ApplySpray evenly from about 25 cm, or brush or dip. For volume work use our spray pump.
- Dry & cureAR grades are touch dry in about 10–15 minutes; ALQ-60, ALQ-100 and SKR-70 are oven cured at 80°C.
- InspectCheck coverage under a UV lamp on grades with a UV tracer before testing.
Exact drying and curing times depend on the grade and film thickness. See each product page or the technical data sheet for details.

PCB Conformal Coating in Kolkata: FAQs
Who supplies PCB conformal coating in Kolkata?
CONINS PUNE manufactures Acrylcoat PCB conformal coatings, Elclean PCB cleaners and external dispensing spray pumps in Pune, India, and supplies them to customers in Kolkata. Acrylcoat is approved by C-DOT, conforms to MIL-I-46058C Type AR and complies with the EU RoHS Directive.
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 Howrah and Kalyani?
Yes. We supply manufacturers in Kolkata, Howrah, Kalyani, Durgapur, Kharagpur and across West Bengal.
How does conformal coating help fan and LED boards in Kolkata?
It forms a thin barrier against moisture and fungus, preventing corrosion and leakage currents. Clear grades like LED-LGT-SPL-60 do not reduce light output.
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.
