SC 11 – Electrical Insulation Coating

Introduction

Electrical safety is paramount in industrial, commercial, and infrastructure settings. SC 11 is a high-performance single-component electrical insulation coating engineered to deliver superior dielectric properties while protecting electrical equipment from environmental factors. Designed for applications ranging from bus bars and control panels to poles and insulators, this innovative coating improves operational safety and reduces maintenance costs compared to traditional solutions like rubber mats.

Key Features and Highlights

• High Dielectric Strength: 122 KV/mm ensures excellent insulation for high voltage systems.
• Temperature Stability: Stable up to 200°C, making it suitable for extreme environments.
• Water Repellent: Highly hydrophobic to prevent leakage currents and contamination flashovers.
• UV and Weather Resistant: Maintains performance under prolonged sunlight and harsh outdoor conditions.
• Fire & Oil Resistant: Protects against fire hazards and transformer oil exposure.
• Mechanical Durability: Puncture, scratch, and abrasion resistant for long-lasting protection.
• Quick Drying: Achieves surface dryness within 15–30 minutes depending on ambient temperature.

Certifications & Testing

SC 11 has been tested under rigorous laboratory and field conditions to meet international standards. It ensures electrical insulation efficiency, resistance to environmental degradation, and consistent performance over long service life.

Recommended Applications

• Control Panels & Bus Bars: Replaces rubber mats and enhances safety.
• Insulators: Ceramic and composite insulators where anti-tracking and dielectric properties are essential.
• Poles & Cross Arms: Prevents bird faults and electrical hazards in distribution grids.
• Instrument Transformers, Bushings, and Current Carrying Conductors: Provides effective insulation.
• Damaged Insulators: Restores electrical strength and prevents leakage currents.
• Outdoor & Industrial Use: Reduces corona effect, minimizes electrical losses, and enhances overall system reliability.

Application Procedure

• Surface Preparation:
  • Clean, dry, and degrease the surface using Cleanol.
  • Remove rust, dirt, oil, and grease.
  • Abrade the surface with emery paper, wire brush, or grinder.
  • Ensure substrate temperature is minimum 3°C above dew point and relative humidity ≤ 80%.
• Coating Application:
  • First coat: Apply uniformly; allow 15–30 minutes to dry depending on temperature.
  • Second coat: Apply uniformly; allow hard drying for 48 hours.
  • Maintain DFT of 80–100 microns.
  • For high voltage grades (M, H, UH), number of coats and DFT may vary.
• Equipment:
  • Air-assisted spray is recommended for uniform coverage.
  • Brush or roller can be used for smaller areas.

Handling & Storage

• Store in a cool, dry, ventilated area away from heat and ignition sources.
• Keep containers tightly closed; handle carefully to avoid spillage.
• Can be used up to 1 year after opening if stored properly.
• Avoid exposure to high humidity during storage to prevent loss of gloss and performance.

Safety Guidelines

• Use under well-ventilated conditions.
• Avoid inhalation of spray mist; wear masks, gloves, and goggles.
• In case of skin contact, wash immediately with soap and water.
• In case of eye contact, flush with plenty of water and seek medical attention.
• Refer to MSDS for detailed safety and handling instructions.

Benefits

• Reliable Electrical Insulation: Reduces leakage currents and contamination flashovers.
• Durable & Long-lasting: Resistant to UV, oil, fire, oxidation, and mechanical damage.
• Eco-Friendly: Single-component, low-maintenance, and safe for occupational use.
• Versatile: Suitable for indoor and outdoor electrical equipment, panels, and high-voltage systems.
• Cost-effective: Reduces maintenance and replacement costs compared to traditional rubber mats.

Case Study: PIDILITE Industries

• Problem: Frequent replacement of rubber mats due to damage, increased leakage currents, and high maintenance costs.
• Solution: Two coats of SC 11 applied at 100 microns DFT.
• Benefits: Excellent electrical insulation, uniform coating properties, eco-friendly, long life, and customizable colour shades.

Conclusion

SC 11 is a premium electrical insulation coating that combines high dielectric strength, UV and moisture resistance, quick drying, and long-term durability. It replaces conventional insulation solutions, improves operational safety, and reduces maintenance costs. Perfect for control panels, bus bars, insulators, poles, cross arms, and other live parts, SC 11 is an essential solution for modern electrical safety and reliability
