Sustainable Acrylic Binder for Durable and Energy-Efficient Cool Roof Coatings

January 26, 2026

Why ENCOR® Flex 1361 Is Different

Rising temperatures, higher energy consumption, and stricter building standards are pushing the roofing industry to rethink coating performance and sustainability. Conventional roof coatings often struggle with dirt pickup, asphalt bleed, and long-term flexibility, reducing reflectivity and shortening service life. ENCOR® Flex 1361 is an all-acrylic latex binder developed to meet these challenges. Designed for elastomeric roof and wall coatings, it supports cool roof performance while aligning with modern sustainability goals. By combining durability, weatherability, and compliance with ASTM D6083 Type II, ENCOR® Flex 1361 enables formulators to create cost-effective, high-performance coatings for energy-efficient buildings.

ENCOR® Flex 1361 Advantages

ENCOR® Flex 1361 supports sustainable roof coating formulations through a balanced combination of performance and environmental considerations:

  • ASTM D6083 Type II Compliance

Designed to meet liquid-applied roofing standards, including flexibility at low temperatures, helping extend roof service life and reduce material waste from premature failures.

  • Low-VOC Formulation Potential

Enables water-based, zinc-oxide-free and co-solvent-free formulations, supporting reduced VOC emissions and compliance with evolving environmental regulations.

ENCOR® Flex 1361: Sustainable Roof Coatings

By maintaining higher reflectivity and durability, ENCOR® Flex 1361 helps translate sustainability into measurable value for building owners and coating manufacturers. Roof coatings formulated with this binder contribute to lower roof surface temperatures, which can reduce cooling demand and energy costs, especially in hot climates. Enhanced dirt pickup resistance supports long-term performance, reducing maintenance frequency and extending recoating cycles. Compliance with ASTM D6083 Type II also provides confidence to specifiers and contractors when selecting materials for restoration or new projects. Overall, ENCOR® Flex 1361 enables more sustainable roof systems that balance performance, regulatory compliance, and total life-cycle cost.
