EFKA SI 2723 has been developed to produce rapid de-aeration of solvent-free polyurethane and epoxy compounds used in flooring application- so that foam and blister-free self-leveling coatings can be produced. It - EFKA SI 2723 can be used in pigmented or non-pigmented resin systems such as solvent-free epoxy and polyurethane systems- low odor- high-solids two-pack systems and solvent-free radiation-curable systems.acts as a leveling agent- giving a smooth surface to the coating. On the other hand- it presents the advantage of low odor.
