## Overview

422B-340G Silicone Conformal Coating is a clear, 340g aerosol designed for high-performance electronic protection. It boasts UL 94 V-0 flame retardancy, withstands continuous temperatures up to 200°C, fluoresces under UV-A light for easy inspection, and is compatible with advanced robotic coating systems. Its superior corrosion resistance and easy reworkability make it the go-to solution for professional-grade circuit board protection.

## Description

Ideal for high temperature environments. Silicone Conformal Coating (422B) is a flexible finish product that provides a protective coating for printed circuit boards against moisture, corrosion, and thermal shock. It protects and insulates electrical and electronic components and assemblies, including generators, motors, transformers, relays, and solenoid coils. For spraying, liquid can be thinned using M.G. Thinner Cleaner. Thin up to one half part thinner to one part coating. Best results will be obtained by applying to thoroughly cleaned and dried parts or materials. It is essential that surfaces be free of any trace of grease or organic substances. At room temperature, the product will tack free in approximately 5-7 minutes, and full cure will be achieved in approximately 48 hours. Curing may be accelerated by applying moderate heat with either a convection oven or infrared lamps. We recommend curing in a convection oven at 65 degree C for one hour, but other temperature and time combinations can work well. Heat curing will improve the physical strength of this coating. ROHS Compliant.

## Customer Reviews

### ⭐⭐⭐⭐⭐ It works as advertised.
*by A***E on September 30, 2024*

I used this product on a 24 year old PCB board for a gate controller. After cleaning the PCB board of old no longer conformal acrylic coating, I sprayed four moderately thick coats from all four directions. After drying over night, the PCB board looked more or less new. Back in the powder coated steel case, rewired, and good-to-go! Great product. Thank-you!

### ⭐⭐⭐⭐⭐ Easy to use and large qty
*by K***O on October 15, 2024*

I coated a PCB with this that will be used in a marine environment. This should keep it from corroding, ideally for at least a couple years but we’ll see. Salt is pretty corrosive.This was easy to use and you can see which areas you are coating so you can find any areas that aren’t coated and give it a quick spray.

### ⭐⭐⭐⭐⭐ Protection from environmental damage
*by D***. on November 7, 2023*

I'm using this product to seal and protect various PCB that will be outdoors 365 days a year. It's a great product, get the silicone coating, it's less prone to cracking and separation.
