EnduRE30C Gen 7 — Metal
EnduRE30C Gen 7 is a premium rare-earth enhanced Passive Daytime Radiative Cooling (PDRC) coating engineered for industrial and commercial metal roofing, facades, tanks, cold-store panels, containers, and long-service-life assets. Built on a fluorocarbon (PVDF-based) binder system, Gen 7 delivers the highest SRI in the EnduRE30C range — and the highest CSIRO-verified SRI recorded in Australia — combined with extreme durability, chemical resistance, and salt resistance for demanding environments.
EnduRE30C Gen 7 works through two complementary mechanisms:
1. High Solar Reflectance — Reflects up to 94.5% of total solar energy, blocking UV and infrared radiation before it heats the metal surface.
2. Infrared Atmospheric Window Emission — Rare earth compounds actively re-radiate absorbed heat through the 8–13 µm atmospheric window directly to the cold sky, even during peak daytime hours.
This dual-action PDRC technology, combined with the fluorocarbon binder, makes Gen 7 the preferred specification for industrial assets, infrastructure projects, and any application where long-term performance and minimal maintenance are critical requirements.

Gen 7 vs Gen 5 — Which to Specify?
Both Gen 5 and Gen 7 deliver CSIRO-verified SRI exceeding 120 on metal substrates. The key differentiator is the binder system and intended service life:
- Gen 5 — Metal uses a silicone-acrylic binder — cost-effective, high performance, suitable for commercial and residential metal roofing where a standard service life is acceptable.
- Gen 7 uses a fluorocarbon (PVDF-based) binder — premium durability, superior chemical and salt resistance, and extended service life. Preferred for industrial infrastructure, coastal environments, and assets where recoating downtime is costly.
Recommended Application System
Prime Coat (A): Epoxy primer — 30–60 µm DFT
Functional Coating (B): Gen 7 Radiative Cooling Special Coating — 80–100 µm DFT
Topcoat (C): Oleophobic Special Topcoat — 15–25 µm DFT
Application method: Airless spray, roller, or brush
Sustainability
By lowering metal surface temperatures and reducing mechanical cooling demand, EnduRE30C Gen 7 supports reduced electricity consumption and associated carbon emissions. Water-based and non-toxic, it is designed to support green building outcomes, NCC energy efficiency compliance, and ESG reporting requirements for industrial asset owners.
Built for Australia's most demanding environments — EnduRE30C Gen 7 delivers the highest verified radiative cooling performance available, with the durability to match.

EnduRE30C Gen 7 for Metal
This page provides practical guidance for applying EnduRE30C Gen 7 Radiative Cooling Coating for Metal, a premium rare earth–based coating system engineered for metal roofs, metal cladding, industrial structures, tanks and outdoor enclosures where long-term durability is required. For detailed procedures and project-specific requirements, always refer to the official Construction Manual.
1) Application Methods
- Airless spray (strongly recommended for uniform film build and performance)
- Air spray
- Roller or brush (limited to small areas, edges, touch-ups and repairs)
2) Drying & Recoat Time
Drying and recoat times depend on temperature, humidity, airflow and substrate condition. Under standard conditions, typical guidance is as follows:
- Surface dry: approximately ≤ 1 hour
- Hard dry: approximately ≤ 24 hours
- Minimum recoat time: 4 hours
- Maximum recoat window: up to 24 hours
Reference conditions: ambient temperature 5–35°C, relative humidity ≤ 75% RH.
3) Application Conditions
- Metal substrates must be sound, clean and dry, free from oil, grease, salt, dust and loose coatings.

Radiative Cooling Principle for Coatings
Stay Cooler, Naturally with Rare Earth Technology
Easyto’s EnduRE30C™ Rare Earth Coatings use advanced radiative cooling to keep building surfaces dramatically cooler under the sun. Unlike traditional paints that only reflect visible light, our coatings combine thermal barrier, solar reflection, and natural radiative emission for all-round heat control. This results in lower indoor temperatures, reduced HVAC loads, and improved energy efficiency.
How Radiative Cooling Works
The coating structure consists of multiple functional layers: a protective surface, a rare earth radiative cooling layer, and a heat-insulating substrate. Together, these layers reflect, block, and re-radiate solar energy — ensuring surfaces stay cooler without compromising durability or aesthetics.
Three Key Mechanisms
1. Thermal Barrier
Heat conduction is reduced by using rare earth materials with low thermal conductivity, preventing excess heat from transferring indoors.
2. Thermal Reflection
The coating reflects solar radiation energy across a wide wavelength range (200–2500nm), reducing the amount of heat absorbed by the building surface.
3. Thermal Radiation
Any absorbed solar energy is re-emitted as harmless far-infrared radiation (8–13μm) back into the sky through the atmospheric window — a natural, maintenance-free cooling process.
Why Rare Earth Makes the Difference
Unlike conventional titanium-based paints, Easyto’s rare earth coatings maintain high stability, strong solar rejection, and long-term weather resistance. This ensures performance does not fade with time and continues to deliver measurable energy savings year after year.
Real-World Benefits
- ✔ Surface temperature reduction up to 30°C
- ✔ Indoor cooling by 5–11°C
- ✔ 25–40% reduction in air conditioning energy load
- ✔ Longer service life with no yellowing or chalking

Applications
Radiative cooling coatings are ideal for metal roofs, warehouses, demountable, telecom cabinets, tanks, animal barns, and more. By staying cooler naturally, these coatings extend material lifespan, improve occupant comfort, and lower operating costs.
