KC 460 Aliphatic Polyurethane

KC 460 is Kool Coats’ premium high-performance aliphatic polyurethane topcoat engineered for maximum durability, impact resistance, and UV stability. Designed as the final armor layer in our elastomeric roof systems, KC 460 delivers exceptional weather resilience and long-term flexibility, even under the harshest environmental conditions.

With tensile strength exceeding 20 N/mm², 150% elongation, and a Shore A hardness of 90, KC 460 forms a tough, seamless protective shell that stands up to thermal stress, abrasion, and chemical exposure. Its cold-applied, moisture-cured formula makes installation fast and simple, while its UV-resistant, non-chalking finish ensures years of reflective protection.

Whether applied over elastomeric base coats or directly to high-wear substrates, KC 460 is the top-tier choice for contractors needing rugged waterproofing and long-term reliability — backed by lab-tested resistance to -40°C to +90°C temperature swings.
