## Overview

MG Chemicals 419D Premium Acrylic Conformal Coating is a 55 mL fast-drying, non-toxic protective layer designed to shield electronic circuits from moisture, corrosion, static, and thermal shocks. Certified UL 94V-0 flame retardant and free of hazardous solvents like toluene and xylene, it offers a crystal-clear finish that fluoresces under UV light for easy inspection. Ideal for professionals seeking reliable, easy-to-apply, and reworkable protection in demanding environments.

## Description

MG Chemicals 419D acrylic conformal coating is fast drying, xylene and toluene free product that provides an excellent finish. This one part coating is easy to use and repair: it does not require special or costly equipment or materials. It is ideal for high moisture environments and applications requiring easy repair and rework. The 419D coating protects electric circuits against moisture, dirt, dust, thermal shocks, and scratches that could corrode, short circuit, or otherwise damage the electric components. It insulates against high-voltage arcing, shorts, and static discharges. As well, this coating provides a high dielectric withstand voltage that allows traces to be put closer together helping with miniaturization.

Review: Don't be a Non-Conformist: Get Professional Results with no Ultra-Violet Curing. - Wear safety goggles. Very strong order, so use in a fan vented area. I coated both sides of an 8x4 inch (200x100 mm) PCB (for a washing machine) in a small bathroom with a vent fan on and it didn't stink up the house. Make sure the PCB is TOTALLY clean else the coating will pull back and leave uncovered spots. I use 95+ Isopropyl Alcohol with an Acid Brush (bristles cut to a stiff 1/4 inch or 6 mm) for cleaning and let it air dry. Make sure the board is above 60 F (16 C) and in less than 50% humidity for at least a day... you don't want to trap moisture in the board. It works well with an Acid Brush with 3/4 inch (18 mm) bristles. I applied the coating in one very thick coat, but two thinner coats may be better. The coating self levels and fully dried in 30 minutes (one side at a time). It is crystal clear and durable. Time will tell if it keeps corrosion at bay in a humid area like a wash room.
Review: Perfect for HV supply repairs - Used it for re-applying insulating conformal coating on an HV 3kV power supply after a reapair. Worked perfectly, no more arcing. Use a mask and gloves when applying.

## Questions & Answers

**Q: What is the shelf-life of something like this? Will it stay usable if I buy this and don't use it until I need it for a long while off?**
A: I have never had good luck with Acrylic coatings. it seems that once you open up the bottle a couple of times the air gets to it and it will thicken up in the bottle in a few months. If you want to have a long shelf life, I would use the Urethane conformal coatings instead. MG Chemicals sells them too.

**Q: I just bought this and it didn't come with a brush cap. Just two brushes sperate in the pack? Anyone get the brush cap lately?**
A: I didnt get the brush cap either. I had to take it from my old bottle. Two brushes is stupid imo. They will just dry up

**Q: Does it effect led output when coated over led lens? I want to use on an led grow light to waterproof but I don't want to reduce the light output.**
A: It is a clear coating, so no visible affects on LEDs, yet silicon coating is recommended for LEDs depending on the temperature.

**Q: How is this different from 422B?**
A: 422 is silicone in a spray can, 419 is acrylic in a bottle.

The spray can is very convenient if you don't mind overspray, you are coating a large area, and want to coat everything in that area.  The material in a bottle allows you to precisely coat areas you want to be coated without contaminating other areas.

Acrylic tends to make a harder surface and be mechanically tough.  Ink, glue, and sticky labels adhere better to acrylic.  Silicone is more resistant to solvents like alcohol and gassoline.  Silicone is also more flexable and less likely to crack under impact, though it is more easily cut.

### ⭐⭐⭐⭐⭐ Dries fast, quality solution for circuit board sealant.
*by W***P on April 19, 2025*

Dries FAST. Has a slight color hue in the glass bottle, reminds of high quality Aerospace coating. Used it on a circuit board in a salt air environment. Time will tell.
