| MG Chemicals 4226A Clear Insulating Varnish |
| Product Description |
| MG Chemicals 4226A is a clear insulating varnish formulated to protect electronic components and circuit boards from moisture, chemical splashes, dust, and electrical arcing. It creates a tough, high-dielectric film on electric motors, transformer windings, and PCB surfaces. Available in 55 mL, 340 g aerosol, 1 L, 3.78 L, and 18.9 L sizes. |
| Technical Specifications |
| • Clarity: Forms a transparent, hard protective layer without obscuring components • Dielectric Strength: Superior protection against high-voltage arcing and short circuits • Resistance: Excellent barrier against humidity, chemicals, and environmental contaminants • Fast Drying: Single-component formula optimized for rapid production cycles • Adhesion: Strong mechanical bond that prevents cracking or peeling over time |
| Applications |
| • Electric motors, solenoid coils, and transformer windings • PCB conformal coating for industrial and automotive electronics • Generator windings and high-voltage switchgear equipment • General industrial maintenance and on-site technical repairs |
| Advantages |
| The transparent finish allows for full visual inspection of components after coating. Its versatile packaging range caters to everything from pinpoint field repairs to mass industrial manufacturing. |
