Unlike generic coatings, its acrylic-silicone blend provides both high-temperature resistance and flexibility, minimizing component stress during thermal fluctuations. This ensures long-term reliability for sensitive electronics, even in India's challenging climate. It's designed for applications where standard coatings might fail, offering peace of mind for critical circuits. **Ideal for PCB Protection in India** — This coating is perfect for protecting printed circuit boards (PCBs) and other electronic components from India's humid atmosphere, dust, and potential corrosion. It's suitable for use in workshops, industrial machinery, and automotive electronics. Skip it if you need a coating for food-contact surfaces or potable water systems, as this product is not certified for such uses. For applications requiring extreme abrasion resistance, consider specialized industrial coatings. ## How to use 1. Ensure the electronic components or PCB are clean, dry, and free from dust, grease, or previous coatings. Lightly abrading or cleaning with a suitable solvent may be necessary for optimal adhesion. — Prepare the Surface 2. Apply a thin, even coat using a brush, spray, or robotic equipment. For best results, apply a second coat within 30 minutes of the first. The coating fluoresces under UV-A light for easy coverage inspection. — Apply the Coating 3. Allow to air dry for 10 minutes, then cure at room temperature for 24 hours. Alternatively, use an oven for faster curing: 20 minutes at 65°C or 10 minutes at 85°C. — Cure the Coating ## Product details | Field | Value | |---|---| | Blend Type | 1-part Acrylic-Silicone | | Maximum Service Temperature | 200 °C (392 °F) | | Handling Time | 10 minutes (room temp) | | Full Cure Time | 24 hours (room temp) or 10-20 min (oven) | | UV Fluorescence | Yes | | Water Resistance | Water Resistant | | Flammability | Flammable (UN1263, Class 3) | | Application Method | Brush, spray, or robotic coating equipment | | Surface Preparation | Ensure surface is clean, dry, and free of contaminants. | | Recoat Interval | Apply second coat within 30 minutes of first coat for best adhesion. | | Cost per use | 55 mL bottle at 1 mL/application = ~55 applications: ₹69.33 per application | | Shelf life after opening | 12 months (typical for coatings) | | Contraindications | Not for food-contact or potable water systems. | | Allergens / common irritants | Flammable solvents; ensure adequate ventilation. | | Brand | MG Chemicals | | Model Number | 422C-55MLCA | | Material | Silicone | | Color | Clear / Transparent | | Container Type | Bottle | | Item Form | Liquid | | Volume | 55 mL (1.86 Fl Oz) | | Item Weight | 50.7 grams | | Dimensions (L x W x H) | 7.68 cm x 2.43 cm x 5.12 cm | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Attributes - **Item form:** Liquid ## Frequently asked questions ### How to buy an original MG Chemicals 422C Silicone Conformal Coating in India?
