Why PCBs in Coimbatore Need Conformal Coating
Many products made in Coimbatore, such as pump starters and agricultural controllers, are installed in farms, borewells and pump houses where they face rain, splashing water, dust and insects. Moisture and contamination on unprotected boards cause failures in the field. Conformal coating seals the PCB and keeps these products working.
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.

PCB Conformal Coating in Coimbatore: FAQs
Who supplies PCB conformal coating in Coimbatore?
CONINS PUNE manufactures Acrylcoat PCB conformal coatings, Elclean PCB cleaners and external dispensing spray pumps in Pune, India, and supplies them to customers in Coimbatore. 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.
Which coating do you recommend for pump starter boards?
Pump starters and controllers often face water and dust, so we usually suggest Acrylcoat ALQ-60 for a thicker film. ELCOAT EL-30, with 60 kV/mm dielectric strength, suits electrical parts.
Do you supply to Tiruppur and Erode as well?
Yes. We supply manufacturers in Coimbatore, Tiruppur, Erode, Pollachi and across western Tamil Nadu.
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.
