IOTA E-30 Epoxy Modified Silicone Resin: The Ideal Base Material for High-Temperature Anti-Corrosion and Insulation Coatings

Hits: 429 img

In the fields of high-temperature anti-corrosion, industrial equipment protection, and electrical insulation, coating materials must simultaneously balance adhesion, chemical resistance, and high-temperature stability. IOTA E-30 Epoxy Modified Silicone Resin, with its dual advantages combining epoxy and silicone properties, can be cured at room temperature or by baking, meeting the stringent requirements of anti-corrosion at temperatures above 500°C and Class H insulation, making it an ideal choice for heavy-duty anti-corrosion coatings and specialty insulation coatings.


Why Choose IOTA E-30

Synergistic Effect of Epoxy and Silicone

  • Combines the high adhesion and chemical resistance of epoxy with the high-temperature resistance and weather resistance of silicone

  • Long-term temperature resistance up to 500°C or higher, suitable for protection of high-temperature equipment, pipelines, and furnaces

Dual Curing Methods, Flexible Application

  • Can be fully cured at room temperature as a two-component system, used with 650 polyamide or T-31 curing agents

  • Can also be cured by high-temperature baking at 180–200°C for 1.5 hours, achieving superior performance

Excellent Comprehensive Protective Performance

  • Good electrical insulation properties and resistance to arcing and corona, meeting Class H insulation requirements

  • Outstanding hydrophobicity, moisture resistance, weather resistance, and chemical stability, suitable for harsh industrial environments

  • Excellent anti-corrosion performance, ideal for protecting internal walls of high-temperature equipment and heavy corrosion environments

Good Process Adaptability

  • Moderate viscosity (20–60 seconds, No. 4 cup), suitable for spraying, brushing, and dip coating applications

  • Solid content of 50±1%, offering good economy and controllable film thickness

Curing and Usage Guidelines

Two-Component Room Temperature Curing

  • 650 Polyamide Curing System: Add 10–15% of the resin weight

  • T-31 Curing System: Add 5–7% of the resin weight

  • Mix thoroughly before application, fully cures at room temperature

High-Temperature Baking Curing

  • Heat to 180–200°C and hold for 1.5 hours for complete curing

  • Baking curing achieves better crosslinking density and overall performance

Dilution and Mixing

  • Xylene is recommended as the diluent solvent; ensure it is free from water and sulfur-containing impurities

  • Stir thoroughly before use to ensure system uniformity


Usage Precautions

  • Diluents must not contain water, sulfur-containing compounds, or pyridine impurities, as these will affect film performance

  • Ensure good ventilation in the application environment, strictly prohibit open flames, and operators should wear protective equipment

  • Keep equipment and tools clean to prevent contamination with dust or moisture

  • Strictly avoid contact with acids, alkalis, and amine compounds during storage to prevent premature curing
