RC-6253 | One-Part Epoxy Coating Resin

LINQCOAT RC-6253 is a solvent-free epoxy resin engineered for use as an impregnation and protective coating material for electronics assemblies. Once cured, it forms a high-gloss, Shore-D 87 network that delivers >25 kV mm⁻¹ dielectric strength, resists moisture uptake (0.1 %), and retains mechanical integrity from −20 to 180 °C. 

LINQCOAT RC-6253 offers a combination of electrical insulation, corrosion protection, and weather resistance, making it a  robust, high-performance material for motors, sensors, and outdoor electronics operating in harsh environments. It also meets the requirements of the 2011/65/EU RoHS directive.

Product Key Features

• High Glass Transition Temperature (140 °C) — Maintains its hard, glassy state and structural integrity at elevated temperatures.
• 14-day Pot Life — Provides extended working time, allowing for easier application, especially for larger or more complex assemblies
• High Dielectric Strength (>25 kV mm⁻¹) — Superior electrical insulation.
• Excellent Moisture Resistance — Absorbs only 0.1% moisture, protecting components from humidity.

Applications

• Provides robust protection and electrical insulation in demanding motor applications.
• Ensures high-performance and longevity for electronics operating in harsh outdoor environments, including those exposed to wide temperature swings and moisture.
