Product Overview

IOTA E30 is an epoxy-modified silicone resin appearing as a pale-yellow to colorless transparent liquid (slight opalescence allowed, free of mechanical impurities). Epoxy modification improves adhesion to substrates and compatibility with curing agents and pigments while retaining the silicone backbone's excellent high/low-temperature resistance, weatherability, and electrical insulation — making E30 an ideal film-forming binder for high-temperature anti-corrosion and insulating coatings.

Key Features

• High-temperature anti-corrosion: widely used in coatings withstanding 500°C and above.

• Flexible curing options: fully curable as a 2K system at room temperature; bake-curing delivers even better performance.

• Good high/low-temperature resistance: withstands thermal shock across a wide temperature range.

• Excellent electrical insulation: suitable for Class H insulating coatings.

• Arc and corona resistance: performs reliably in high electric field environments.

• Hydrophobic and moisture-proof: the coating repels water and protects substrates from moisture attack.

• Comprehensive durability: weatherability, chemical stability, and corrosion resistance.

Frequently Asked Questions (FAQ)

Q: What is the maximum service temperature of IOTA E30? A: As a high-temperature anti-corrosion coating binder, it withstands 500°C and above.

Q: How does IOTA E30 cure? A: It fully cures as a two-component system at room temperature; bake-curing yields even better coating performance.

Q: What type of resin is IOTA E30? A: It is an epoxy-modified silicone resin, combining silicone's heat resistance, weatherability, and insulation with epoxy's adhesion and reactivity.

Q: What is the epoxy value of IOTA E30 and why does it matter? A: The epoxy value is 0.02–0.07. It determines the crosslinking reactivity with curing agents (e.g., amines) and is a key parameter for calculating hardener dosage in formulations.

Q: What is the viscosity of IOTA E30? A: 20–60 seconds measured with a Ford Cup No. 4 (Tu-4 cup); application viscosity can be adjusted with suitable solvents.

Q: Can IOTA E30 be used as an insulating coating? A: Yes. Its electrical insulation meets Class H requirements, suitable for motors and electrical apparatus.
