EnduRE30C Rare Earth Insulation Coatings

CSIRO-Verified Solar Reflectance Index (SRI)

Every EnduRE30C product is independently tested by CSIRO Infrastructure Technologies in accordance with ASTM E1980-11, ASTM E903-20, and ASTM E408-19 — providing the verified performance data your project specifications demand. Achieved SRI values exceed 100, meaning treated surfaces run cooler than a standard white benchmark:

• EnduRE30C Gen 5 (Concrete & Metal) — SRI 120.8 | Solar Reflectance 0.932
• EnduRE30C Gen 7 (Metal / Industrial) — SRI up to 122.8 | Solar Reflectance 0.945
• EnduRE30C Flexi (Flexible Substrates / PVC) — SRI 111.5 | Solar Reflectance 0.873
• EnduRE30C WaterLock (Waterproof & Heat-Insulating) — SRI 104.9 | Solar Reflectance 0.831

How Rare Earth Radiative Cooling Works

Unlike conventional cool roof paints that only reflect sunlight, EnduRE30C works through two complementary mechanisms:

1. High Solar Reflectance — Reflects over 93% of total solar energy, blocking UV and infrared radiation before it heats the surface.
2. Infrared Atmospheric Window Emission — Rare earth compounds actively re-radiate trapped heat through the 8–13 µm atmospheric window directly to the cold sky, even during peak daytime hours.

The result: up to 25–40% reduction in building cooling energy costs with zero mechanical energy input and no ongoing maintenance.

Products for Every Substrate

The EnduRE30C range is engineered to meet the demands of commercial and industrial builds across a full range of substrates:

• Metal roofing, Colorbond & colour steel sheets — Gen 5 (Metal) or Gen 7 (PVDF fluorocarbon, premium durability for industrial facades)
• Concrete rooftops & masonry walls — Gen 5 (Concrete), silicone-acrylic with high penetrating adhesion to porous substrates
• Flexible & PVC membranes — Flexi, elastomeric with 223% elongation at break for movement-prone surfaces
• Roofs requiring waterproofing + cooling — WaterLock 2-in-1, an integrated system tested to JG/T 375 with 75% solid content and 2.0 MPa tensile strength

✔ SGS certified | ISO 9001 / 14001 / 45001 manufacturing
✔ 600-hour UV weathering resistance, zero blistering or cracking
✔ Water-based, non-toxic, VOC-compliant — safe for occupied buildings
✔ 18-month shelf life | Applies by airless spray, roller, or brush
✔ White or custom colours to match project specifications

Suitable Project Types

EnduRE30C is specified on warehouses, factories, cold storage and logistics facilities, data centres, aged care buildings, schools, strata complexes, and large-format commercial rooftops. Also suitable for residential homes with concrete tile, terracotta tile, or Colorbond steel roofs where summer heat buildup is a comfort and energy concern. Ideal for animal barns, livestock sheds, and rural outbuildings where air conditioning is not practical — reducing heat stress on animals and improving shelter conditions passively. Particularly effective across QLD, NSW, WA, NT, and SA where uncoated metal and concrete roof surfaces routinely exceed 70°C in summer — driving significant mechanical cooling loads.
