8503 CrownFlex is a two-component, 100% solids, semi-rigid thixotropic epoxy cove base binder, orange peel coating and a sag-resistant control joint and cracks filler. It features a combination of excellent adhesion and elongation not available in general-purpose epoxy. It is formulated to provide the armoring of concrete joint edges and minimizing the deterioration of concrete joint/crack edge to impact. It is available in standard cure and fast cure. For armoring concrete joint and crack edges use 8503 CrownFlex instead of elastomeric sealants that meet ASTM C920 Standard Specification for Elastomeric Joint Sealants which do not armor the concrete joint or crack edges. It is used on floors, joints, and cracks subjected to heavy foot traffic, forklift traffic, and chemical attack, specifically food acids. Also, it is used as an epoxy membrane for waterproofing and crack dampening under epoxy coating and flooring systems. It is VOC Compliant in all states and provinces in North America.
