We are ranked amongst the distinguished Suppliers of Premium Polyurethane Conformal Coating (4223D) in Maharashtra, India. Our 4223D Premium Polyurethane Conformal Coating is a heat curing, one part product that provides an excellent scratch and chemical resistant 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 chemically challenging environments. The 4223D urethane protects the electric circuits against the aggressive chemicals, moisture, dirt, dust, thermal shocks, and scratches. This avoids corrosion and physical damages to electric components. It insulates against the high-voltage arcing, shorts, and static discharges, allowing the traces to be put closer to one another.

Features :

  • Type UR
  • Certified UL 94V-0 (File # E203094)
  • Excellent finish smooth, flexible, mar resistant
  • High Chemical Resistance resists water, solvents, and most household chemicals
  • Durable abrasion resistant
  • 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
  • Removable with MG 8310 Conformal Coating Stripper
  • Free of isocyanate

Applications & Usages :

  • The 4223D coating improves reliability, operational range, and lengthens the life of electrical and electronic components and assemblies. It finds application specially for corrosive environments such as those found in the farming, mining, smelting, oil exploration, and marine industries.
  • Common urethane conformal coatings uses are with electric generators, motors, transformers, relays, and air bag controllers. Commercial applications include fire alarms components, sensors, automotive electronics, electrical connectors, and porcelains.


Spray Gun 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 accelerate cure by heat
  • After flash off, put in oven or under heat lamp at ≤80oC for 18 hours.
