PRIMAL™ EC-5210 PU

Looking for a waterproofing solution that has excellent tensile strength and flexibility in hot and cold conditions? This acrylic polyurethane dispersion withstands weathering and UV exposure, resists dirt pick-up, and adheres well to various roofing substrates.

PRIMAL™ EC-4642 ME

This acrylic copolymer is designed for hot climates. Used for protective and reflective elastomeric roof coatings, it improves wet and dry adhesion over various substrates. It offers long-lasting performance, UV resistance, low-temperature flexibility, and resistance to dirt pick-up.

RHOPLEX™ EC-2020

This all-acrylic polymer offers elastomeric roof coatings with excellent flexibility and dirt pick-up resistance, reliable asphalt bleed resistance, and strong adhesion to common roofing materials. It allows coatings to be formulated to meet ASTM D6083 TYPE I and TYPE II standards.

Preserving roofs, less waste

Applying a roof coating can extend the life of a roof. For both new and retrofit installations, regular recoating can help preserve and protect the original roof, reducing landfill waste and the need for new building material

Safety and longevity

Waterborne acrylic technologies reduce volatile organic compounds, which makes for safer application, while still offering durability and easy cleanup with soap and water.

Improving energy efficiency of buildings

Energy efficiency in modern buildings offers significant potential for achieving reduced CO2 emissions and improving living standards. The most significant contribution to this is reducing the amount of energy used to control the internal temperatures of buildings.
