Product Overview

IOTA-6056D is a pale-yellow to colorless transparent liquid (slight opalescence allowed, free of mechanical impurities) with a solid content of 55±1%. Its phenyl structure delivers high thermal stability — no yellowing at elevated temperatures, low smoke emission, and a high temperature rating — while providing outstanding gloss, fullness, and film hardness that combine decorative appearance with long-term protection under extreme conditions.

Key Features 

• High temperature rating: widely used as the base resin for coatings withstanding 500°C and above.

• Non-yellowing at high temperature: film color remains stable during prolonged heat exposure.

• Low smoke emission: suitable for furnaces, flues, and other applications with cleanliness or low-smoke requirements.

• High hardness and excellent appearance: ≥2H Chinese pencil hardness after full cure, with high gloss and good fullness.

• Rapid room-temperature surface drying: reaches touch-dry with measurable hardness quickly, ideal for on-site and large-area application.

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

• Arc/corona resistance, weatherability, chemical stability: comprehensive durability.

• Hydrophobic and moisture-proof: the film repels water and blocks moisture ingress.
