Kraton G1643 Roof Coating Formulation Exceeds ASTM D6083 Requirements

Houston, TX /PRNewswire-FirstCall/ - Kraton Performance Polymers, Inc. (NYSE: KRA), a leading global producer of styrenic block copolymers or "SBC's" (together with Kraton Polymers LLC and its other subsidiaries, "Kraton"), announced that its roof coating formulation containing Kraton G1643, a styrenic block copolymer (SBC), exceeds requirements in the ASTM International D6083 standard specification recognized in the elastomeric roof coating market.

ASTM D6083 is an industry standard that establishes minimum performance levels in the following areas: viscosity, weight and volume solids; mechanical properties; adhesion; low temperature flexibility after accelerated weathering; tear resistance; permeation and water swelling; and fungi resistance. This gives innovators an opportunity to more effectively compare polymer-to-polymer for roof coating formulations.

"We are very pleased to announce that G1643, the Kraton polymer used in elastomeric roof coating formulations, surpassed ASTM D6083 requirements," said Mark Siebert, Vice President, Adhesive, Sealants and Coatings. "This SBC based polymer has a proven track record of improving the performance of roof coatings because it adds superior water resistance, improved adhesion, and increased elongation to formulations. It can be used to help lower volatile organic compounds (VOCs) in a solvented formulation, which have significant vapor pressures that can affect the environment and human health. In addition, our tested formulation can be used under the EPA's regulation for thermoplastic rubber coatings and mastic," he concluded.

A roof coating formulation containing Kraton G1643 can reduce total cost of installation and provide fast cure coatings that will work better in cold, humid, or wet conditions. Elastomeric roof coatings made with Kraton polymers will stand up better to ponding water, and provide excellent adhesion to all types of roofing substrates. Roof coatings made with Kraton G1643 are an excellent choice for low slope roofs, or high traffic areas, and will provide excellent reflectance to reduce energy costs, and extend the life of the roof.
