CHT Group EP JS EPI Engineered Polymers Joint Sealant
Categories:	Polymer; Thermoset
Material Notes:	EP JS Joint Sealant JS, “Powered by Reactamine® Technology” is a two component 100% solid (silicone optional) polyurea based joint sealant. EP JS is a self-leveling joint sealant designed to protect interior horizontal concrete expansion and control joints from spalling, chipping, and breakdown. This elastomer displays fast cure times and excellent adhesion to concrete. EP JS can be applied at temperatures ranging -30° F to 350°F. This polyurea elastomer displays excellent chemical resistance, water insensitivity, and thermal stability at high and low temperatures. EP JS may also be used under traditional floor coatings (such as epoxies, polyureas and polyurethanes) or tiles to smooth the joints and provide protection from cracking and sinking caused by non-elastomeric joint sealants. Applications:EP JS was designed to protect against the abuse to concrete joints caused by heavy load transfers from such items as forklifts, steel-wheeled carts and trash dumpsters. Some typical uses include: Concrete Control / Expansion Joints Concrete Spall Repairs Cold Storage Facilities Merchandise Distribution Centers Home Improvement Stores Bridge Headers Warehouse Floors D.O.T. Pothole Road Repair U.S.D.A. and F.D.A. Acceptable Part of the Amber Chemical Group. Data provided by manufacturer. Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
