High-performance barrier coatings based on Kraton™ SEBS polymers protect metal, concrete and plastic surfaces against damage from water, air, chemicals, salt spray and other corrosive elements. These coatings retain outstanding toughness and flexibility to resist cracking and ensure long, maintenance-free service life.
Kraton™ G SEBS polymers provide outstanding adhesion to metals and non-polar materials like plastics and composites. The polymers can be blended with Kraton™ A1536 to produce harder coatings. Coatings with functionalized Kraton™ FG1901 SEBS and Kraton™ RP6670 SEBS deliver exceptional substrate adhesion, durability and corrosion-resistance. These coatings are ideal for the protection of piping, concrete, architectural structures and vehicle undercarriages. It can also be used in building envelope applications such as waterproofing foundations and other structure sections.
