Certi-Vex Clean Lift bond breakers in water and low VOC solvent versions, feature a proprietary formulation of chemically active release agents which form microlayers on the concrete surface. These layers are the foundation for the only chemically active bond breakers independently tested to meet all the requirements of ASTM C 309. The breakers improve the quality and performance of the floor, and significantly reduce or eliminate crazing, carbonization, curling, panel surface defects, and osmotic effect. They are efficient, fast membrane forming, reactive bond breakers. Vexcon Chemicals. 215-332-7709. www.vexcon.com [WOC Booth S11115]
