The audio magazine of WACKER shows the many exciting roles chemistry plays in everyday life. Each instalment will give you interesting insights into how chemistry ensures perfectly functioning products in all areas of life. Whether it is drugs, computers, cleaning agents, clothing or toys - WACKER products play a vital role almost everywhere.
Episode 74: Low-emission paints
An unpleasant odor often lingers in the room after the walls have been painted. This is caused by the volatile organic compounds in the paint. WACKER chemists have succeeded in developing a binder for paints that only emits minimal amounts of such undesirable substances. VINNAPASreg; EP 3560 even meets the Scandinavian ecolabel's stringent requirements - and makes the paint disperse better than before, while preventing salts from forming white spots on the paint.
Episode 73: Standing Up to Damp
Waterproofing membranes are indispensable in protecting the building fabric against damp. But until now, it was not possible to use a toothed applicator to apply them, the tool of choice among workman in this country. The mass simply wasnrsquo;t firm enough, and the ridges merged. Thatrsquo;s why WACKER developed the polymer VINNAPASreg; 7150 E, which solved the problem. Not only does it comply with the standard for crack-bridging, it is also very low in emissions.
Episode 72 – Polymer Concrete for Olympic Buildings
The architecture of the Olympic venues in Munich is in a class of its own. What few people know is that the buildings were among the first to have a polymer-modified mortar blended in with their concrete. Polymers like VAE from WACKER make concrete more flexible and improve its adhesion. The ability to mix them into the mortar in dry form was new at the time and ultimately opened the door to the thin-bed method for laying tiles. The concrete structures in Munich are still standing.
Episode 71 – Chewing gum in any shape
Chewing gum in the shape of a heart? We can do that! Until now, however, chewing gum has undergone an elaborate mixing process using gum base, which limits the variety of shapes. Now thatrsquo;s all going to change: With CAPIVA C03, WACKER has developed a new gum base that melts completely so that the popular confectionery can now also be molded - into any shape. Manufacturers also have an advantage: Their equipment can be easily cleaned after production.
Episode 70 – Renewed Splendor for Flooring in Budapest Train Station
Terrazzo flooring looks well - but not for long. Coffee and chewing gum render it unsightly with time. A protective coating based on a silane-modified polymer from WACKER has come to the rescue. Only one component needs to be applied ndash; entirely without solvents. And the floor can be walked on after 48 hours. Experts have demonstrated this on several buildings around the world. Among them Budapestrsquo;s Western train station, built by Gustave Eiffel.
Episode 69 – Just the Right Amount of Foam
In many countries around the globe, washing is still done by hand. People believe it ought to foam properly ndash; because thatrsquo;s supposed to be a sign of effective cleaning. Yet this foaming is a problem, since after washing, laundry has to be rinsed out many times until all of the foam disappears. This is why researchers at WACKER have developed a defoaming agent that only begins to take effect during rinsing, halving the amount of water used.
