We are one of the leading Suppliers of Premium Acrylic Conformal Coating (419D). Our 419D Acrylic Conformal Coating is a fast drying, xylene and toluene-free product that provides an excellent finish. This one part coating is easy to use and repair, as it does not require any special or costly equipment or materials. It is ideal for the high-moisture environments and applications requiring easy repair and rework. The 419D coating protects the 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.

Features :

• No Hazardous Air Pollutants free of toluene and xylene
• Certified UL 94V-0 (File# E203094)
• Excellent finish  smooth, homogeneous, and durable crystal clear coat
• Protects electronics from moisture, corrosion, fungus, and static discharges
• Easy to inspect  fluoresces under black light (UV light)
• Easy rework and repairs can solder through coat; remove with MG Chemicals' Thinner/Cleaner, Thinner 4, or Conformal Coating Stripper

Applications & Usages

• The 419D coating improves reliability, operational range, and lengthens the life of electrical and electronic components and assemblies. Its primary applications are in the automobile, marine, aerospace, aviation, communication, instrumentation, industrial control equipment, and consumer electronics industries

 Application Instructions : Follow the procedure below for best results.

• To apply the required thickness by weight :
  • Mix thoroughly, and spray a test pattern. This step ensures good flow quality and helps establish appropriate distance to avoid runs.
  • At a distance of 20 to 25 cm (8 to 10 inches), hold the gun at around 45°, and spray a thin and even coat onto the horizontal board. For best results, use spray-and-release strokes with an even motion to avoid excess paint in one spot.
  • Before the next coat, rotate the board 90° to ensure good coverage.
  • Wait at least 2 minutes, and spray another coat. The delay avoids trapping solvent between coats.
  • Apply other coats until desired thickness is achieved. (Go to Step 3)
  • Let dry for 3-5 minutes (flash off time) at room temperature.

• To cure at Room temperature:
  • Let air dry 24 hours
  • To accelerate cure by heat:
  • After flash off, put in oven or under heat lamp at ≤65^oC for 60 min.

Note :

• Coats that are very thick require more time to dry.
• Attention - If heat curing, do not exceed 65^oC as this may cause surface defects due to solvents evaporating off too quickly.

4223F is a 1-part, heat curing, UL 746E certified, thermoset polyurethane conformal coating. It cures to a durable, flexible, scratch resistant, and smooth finish. It is easy to apply and can be handled in 15 minutes. It cures in only 2 hours at 100 °C (212 °F). It may be removed with appropriate strippers, or soldered through for repair or rework.

4223F protects printed circuit boards in chemically challenging environments. It provides strong protection against aggressive chemicals,  corrosion, moisture, fungus, dirt, dust, thermal shock, abrasion, short circuit, high-voltage arcing, and static discharge.

We are engaged in supplying Silicone Conformal Coating (422B) in Maharashtra, India. 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 the electrical and electronic components & assemblies including generators, motors, transformers, relays, and solenoid coils. For spraying, the liquid can be thinned by using M.G. Thinner Cleaner. Thin up to one-half parts thinner to one part coating.

Details :

• Certified UL 94V-0 (File # E203094)
• Maximum Service Temperature of 200^oC
• Fast Cure - tack free in 6 min at room temperature, full cure in 20 min at 65^oC
• Protects electronics from moisture, corrosion, fungus, thermal shock, and static discharges
• Easy to inspect: fluoresces blue at 437 nm ± 65 cm under UVA light
• Extended Shelf Life avoids worries about premature hardening and wastage
• Easy rework and repairs

Directions of Use

• 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^oC (149^oF) for one hour, but other temperature and time combinations can work well. Heat curing will improve the physical strength of this coating.
