“We are far and away the world’s number one supplier of dispersible polymer powders,” stresses Dr. Christoph Riemer, head of Construction Polymers business unit at WACKER. “And our current expansion program gives a clear signal that we intend to keep our lead!”
The benefits of the VINNAPAS® dispersions are particularly apparent in modern, porcelain stoneware tiles fired at high temperatures and glass mosaics. “Because of the lack of pores, the mortar does not penetrate as much, and the crystals that form as it hardens are unable to interlock with the tile, which therefore does not grip as well as it might,” explains Klas Sorger, technical service manager for Construction Polymers at WACKER in Burghausen. The binders act like a glue between the mortar matrix and the tile. When the cement in the mortar sets, the polymer particles fuse together, forming so-called resin domains that provide the necessary adhesion.
