Composition and Material Properties
AZ-2100-IECW belongs to a specialized category of ESD paint formulations designed for aerospace applications. Its unique material composition enables its exceptional performance characteristics.
The coating consists of several key components:
- Zinc Oxalate - Contributes to the coating's thermal properties
- Tin Oxide - Provides electrical conductivity and ESD protection
- Potassium Silicate - Creates a durable inorganic binder matrix
- Distilled Water - Serves as the carrier medium
This inorganic composition gives the ESD paint several advantages over organic alternatives:
- Greater resistance to ultraviolet radiation damage
- Excellent stability in vacuum environments
- Superior durability at temperature extremes
- Reduced outgassing in space conditions
- Enhanced long-term performance retention
The absence of volatile organic compounds makes this ESD paint environmentally friendlier during application while also reducing contamination risks in sensitive spacecraft assembly environments. This characteristic is increasingly important as aerospace manufacturers adopt more sustainable practices.
