Conformal Coating Spray

[EEVaditya]

Hello,

Looking for good quality Hand Spray type Conformal Coating for my PCB.

Any recommendations & suggestions for Automotive as well as general purpose application.

Depends what country you are in.
Canada would be this: https://www.rpelectronics.com/422a-340-conformal-coating-mg-chemicals.html
Needs extremely good ventilation wherever you are using it.

I've used the acrylic version of the MG conformal coating:

Went on well without running - I used it in this video:

The silicon one from thm_w's post is from the same manufacturer - MG Chemicals also has epoxy and polyurethane ones

@Tony_G & thm_w

are there any other alternatives?

which are good quality and with moderate rates.

in the range of 500-1500 INR (8 USD-20 USD)

these mg chemicals products are out of budget.

Unfortunately I've only every used the MG Chemicals one (it worked very well for me so I never went looking elsewhere) - thm_w may have more experience.

That said, you can probably use any spray on polyurethane or silicone material - You want to get the MSDS for whatever you choose and ensure that there aren't any ingredients that would cause problems (you want it to be basically the coating, thinner and propellant).

Also I see that the paint brush versions of it are cheaper (probably less area coverage per bottle though).

Sorry I couldn't help more.

Electrolube do range of them,  they have worked well for me in the past. They contain UV trace so easy to inspect the quality of coverage.
