## Overview

MG Chemicals 419D Premium Acrylic Conformal Coating is a fast-drying, clear protective layer designed to safeguard electronic circuits from moisture, corrosion, static, and thermal shocks. Certified UL 94V-0 flame retardant and free from hazardous solvents like toluene and xylene, it offers a smooth, durable finish that fluoresces under UV light for easy inspection. Ideal for high-moisture environments, it supports easy rework by allowing soldering through the coating or removal with specialized thinners.

## 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: Good product but the silicone modified coating is better. - Great product, UV illumination, brushes can be easily cleaned with Isopropyl alcohol and be reused, you should know that the acrylic does not bond to the surface, it is merely a coat that can be pretty easily scratched off, useful for rework but the board should be protected from physical damage or it will easily break seal. To protect from damage during manipulation, I would recommend the silicone modified coating or liquid electrical tape.
Review: Works Great: Use Caution While Applying - I use this coating on PCBs that are milled on a CNC. Sealing these PCBs makes sense as I live in a high humidity environment. This material dries to the touch in about 30 minutes, but I give it 24 hours to fully cure. VERY IMPORTANT: 1) Heed the WARNINGS re the very flammable vapors and DO NOT breathe this stuff as it's quite dangerous. But, after it cures, the VOCs decrease enough that I can barely smell any. 2) Wear a respirator (Do NOT use a N95/KN95/surgical type mask), even if using outdoors. Also, wear safety glasses, and gloves (I use Nitrile) when applying. CLEANING: As noted, there are 2 included brushes. However, I use "acid brushes" (you can buy these in bulk) and both 70% and 99% isopropyl alcohol to clean the acid brushes. You'll need to use a paper towel and work the brush end to get the coating to "glob" up and detach from the brush. It's a bit of work, but you can reuse a brush several times. Handy Hint: Acid brushes tend to have 3/4" bristles. I cut these down to a tighter 1/4" for more accurate application. Have fun, but be safe! Picture: This closeup shows what a coated and non-coated area looks like after curing. When wet it has a slight pinkish tinge but, as shown, it dries clear.

## 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.

### ⭐⭐⭐⭐⭐ MG Chemicals 419D 🛡️ recubrimiento acrílico excelente para proteger PCB con precisión
*by X***. on 17 December 2024*

Revestimiento de conformación acrílico transparente para proteger placas electrónicas, soldaduras, pistas y componentes frente a humedad, polvo, suciedad y pequeños riesgos de corrosión superficial. Le doy 5 estrellas porque cumple muy bien como barniz técnico para PCB, especialmente en reparaciones, modificaciones o trabajos donde interesa aislar zonas sensibles, pero exige preparación, ventilación y una aplicación fina y controlada. Valoración: ⭐⭐⭐⭐⭐ 4.8/5 🧪 Qué producto es 🛡️ Es un conformal coating acrílico transparente, pensado para formar una película protectora sobre placas electrónicas. 🔬 Tiene sentido en PCB, soldaduras, zonas reparadas, placas expuestas a humedad ambiental o trabajos donde se quiere añadir aislamiento superficial. ⚡ No es pegamento, no es pasta térmica y no es silicona: es un recubrimiento protector. 🧴 El formato pequeño de 55 ml viene muy bien para trabajos precisos, reparaciones puntuales y electrónica de detalle. 🧱 Al ser acrílico, resulta más manejable que otros recubrimientos más permanentes, como algunos epoxi o siliconas técnicas. 🛠️ Aplicación y uso real 🧽 Lo más importante es limpiar bien la zona antes de aplicar: sin grasa, flux, polvo ni restos de humedad. 🖌️ Conviene aplicar capas finas, no una capa gruesa de golpe. Así seca mejor, queda más uniforme y se reduce el riesgo de burbujas o acumulaciones. ⏱️ Hay que respetar el tiempo de secado antes de montar, cerrar o alimentar el equipo. 🌬️ La ventilación es obligatoria: huele a disolvente y no es un producto para usar en una habitación cerrada sin extracción. 📐 Para zonas delicadas, va muy bien aplicarlo con pincel fino, palillo o herramienta de precisión, especialmente alrededor de componentes pequeños. ⚠️ Advertencias técnicas importantes ⚡ No debe aplicarse sobre conectores, pads de contacto, ranuras, contactos de batería, zócalos, interruptores, sensores, puertos USB, pines o zonas que necesiten conductividad eléctrica. 🔥 Hay que mantenerlo alejado de fuentes de calor, chispas o llamas mientras se aplica y seca. 🔌 No se debe alimentar la placa hasta que el recubrimiento esté correctamente seco. 🧯 En placas con componentes muy calientes, conviene evitar cubrir zonas que necesiten disipar calor directamente. 🔎 Si se usa como protección alrededor de metal líquido, sirve para aislar componentes cercanos, pero no sustituye una aplicación cuidadosa del metal líquido ni evita daños si se derrama demasiado. 🧤 Mejor usar guantes, buena luz y trabajar con calma, porque una mala aplicación en conectores o mecanismos puede dar más problemas que soluciones. ✅ Lo que más me ha gustado 🛡️ Muy útil para proteger PCB y zonas reparadas. 🔬 Permite aislar componentes pequeños con bastante precisión. 🧴 El formato de 55 ml es práctico para trabajos puntuales. 🧱 Acabado transparente y limpio si se aplica en capas finas. ⚙️ Buena opción para electrónica, reparaciones y modificaciones delicadas. 🧽 Una vez seco, deja una película protectora bastante discreta. 📦 Ocupa poco y dura bastante si se usa sólo donde hace falta. 💶 Muy buena relación utilidad-precio para quien trabaja con placas. ⚠️ Lo que menos me ha gustado 🌬️ El olor a disolvente obliga a usarlo con buena ventilación. 🖌️ Hay que aplicarlo con cuidado para no invadir conectores o contactos. ⏱️ Requiere esperar bien el secado antes de manipular o alimentar la placa. 🧼 La preparación previa de la superficie es clave; si aplicas sobre suciedad o flux, el resultado empeora. 🔎 En trabajos muy pequeños hace falta buena luz y pulso. ⚡ No perdona tanto como parece: si cubres una zona que debe hacer contacto, toca limpiar o rascar. 📐 No es producto para usar “a lo bruto” sobre toda una placa sin pensar qué zonas conviene enmascarar. 📊 Notas por criterio 🛡️ Protección de PCB: 4.9/5 🔬 Precisión de aplicación: 4.6/5 🧱 Acabado transparente: 4.8/5 🧴 Formato y aprovechamiento: 4.7/5 ⚙️ Utilidad en reparaciones/mods: 5.0/5 🌬️ Comodidad de uso: 4.0/5 ⚠️ Exigencia técnica: 4.2/5 💶 Relación calidad-precio: 4.8/5 🧮 Resultado ponderado 0.25×4.9 + 0.15×4.6 + 0.15×4.8 + 0.10×4.7 + 0.15×5.0 + 0.05×4.0 + 0.05×4.2 + 0.10×4.8 = 4.76 Redondeo final: 4.8/5 🧠 En resumen Me parece un recubrimiento acrílico muy bueno para proteger electrónica cuando se usa con criterio. Es especialmente útil en placas reparadas, zonas expuestas, trabajos de soldadura, mods y aislamiento de componentes pequeños. El acabado transparente queda limpio y permite proteger sin dejar una capa aparatosa. La clave está en no tratarlo como un barniz cualquiera. Hay que limpiar, enmascarar lo que no se debe cubrir, aplicar poca cantidad y dejar secar bien. Bien usado, aporta mucha tranquilidad en zonas delicadas; mal usado, puede terminar aislando conectores o contactos que no debían cubrirse. 🎯 Veredicto El MG Chemicals 419D-55ML me parece un producto excelente para trabajos técnicos en PCB. Le doy 5 estrellas porque cumple justo lo que espero de un conformal coating acrílico: protege, aísla, deja buen acabado y permite trabajar con precisión en reparaciones o modificaciones electrónicas. No es para aplicarlo sin pensar ni para cubrir toda una placa indiscriminadamente. Hay que tener claro qué zonas proteger y cuáles dejar libres. Usado con ventilación, limpieza previa, capas finas y paciencia, es una herramienta muy útil para electrónica fina, mantenimiento, reparaciones y protección adicional en montajes delicados.
