Flexible Epoxy Binder for Mortar, Slurry and Chip Seal Overlays


Kemko® 128, FlexDek Binder is a two-component, medium viscosity, low modulus, epoxy binder designed specifically for concretedeck protective overlays. Used in conjunction with suitable aggregate, a Kemko® 128 mortar, slurry chip seal will protect concretedecks from abrasion, wear, and intrusion of deleterious chemicals including vehicular and aircraft fluids and pavement de-icingcompounds. The binder’s viscosity, short cure cycle, and low modulus mechanical properties make it ideally suited for a variety of overlayapplications. Each type of installation may have specific application and performance requirements. Evaluation of trial mixes particularlyunder low-temperature conditions prior to installation is recommended.


Unlike many other exterior use epoxy binders, Kemko® 128 does not embrittle when exposed to sunlight for long periods of time and is environmentally safe. The product has a convenient 2:1 (by vol.) mixing ratio and a fast cure cycle for short downtimes. Kemko® 128 is formulated for high-build film thickness and high aggregate loading. The components do not contain volatile solvents (VOCs).
