Replaces Water Spraying & Thermal Coatings

Core Competencies

Purpose
Preventing rail buckling and derailments due to elevated rail temperatures in summer.

Material Composition

Rubber magnets, adhesives, glass fiber base, epoxy primer, fluorine topcoat

Solar reflectance 85%, temp. reduction up to 7.4 °C (open) / 4.8 °C (tunnel), enhanced to 9.8 °C with roll-to-roll process

Stable under 65 m/s wind & 300 km/h trains; 10-year durability (99% in climate, 95% in pollution)

Detachable non-coated structure for easy inspection & seasonal use

Compatible with automated equipment, scalable for field use

Expected Benefits

Safety & Punctuality
– Removes speed limits in heat, prevents derailments
Reduced Water Consumption
– 180+ tons saved annually vs. spraying
High Operational Efficiency
– All-in-one equipment cuts operation time 70%+, covers 2 km/day
Versatile Application
– Usable for rails & other heat-exposed infrastructure

Certifications

New technology with no prior application in the domestic or international railway sector
Not yet included in existing maintenance standards or design guidelines
Undergoing international standardization in cooperation with ISO/IEC

TRL 7

Osong open test section: Demonstration in actual train operation under outdoor exposure conditions
Gwangju enclosed section: Testing under heat accumulation conditions in a tunnel-like rail environment
Full-scale demonstration with KTX-Eum trains on the Jungbu Inland Line scheduled for summer 2025
