Foam Jackets for Steel Columns

Mar 27, 2013

Sports stadiums, skyscrapers and airport terminals are just three examples of the increasing number of new buildings going up in metropolitan areas at a breathtaking rate. They predominantly feature roofs and frames made of steel, because steel skeletons have a low dead load, but a high load-bearing capacity and are usually quick and easy to assemble. However, the higher and larger the building, the greater the importance of fire protection. To prevent the steel frames of skyscrapers and stadiums from buckling within minutes during a fire, they are provided with special fire protection coatings. As the binder, a new dispersion by WACKER ensures the necessary elasticity, strength and adhesion of the protective layer.

    Fire test: Intumescent Coatings

    Fire test: Intumescent coatings encase steel girders and, in case of a fire, form an insulating foam barrier, thus protecting the steel structure from the heat – and dispersions from WACKER play a key role here as a binder (photo: Clariant Produkte Deutschland GmbH - 2013)

    Modern buildings often feature steel skeletons – but when the temperature reaches 500°C, steel frames soften rapidly. To prevent them from buckling within minutes during a fire (left), they are provided with special fire protection coatings, allowing them to resist a fire for much longer (right). The polymer binders VINNAPAS® EZ 3112 and VINNAPAS® EZ 3066 ensure significant foam development in these coatings, coupled with improved adhesion and strength.

    VINNAPAS® LL 3112 - Foam Development

    In case of a fire, intumescent coatings foam to tens to hundreds of times its original thickness and act as a heat barrier. The new VINNAPAS® LL 3112 binder ensures significant foam development in these coatings, coupled with improved adhesion and strength (photo: Clariant Produkte Deutschland GmbH - 2013).

    Lab test of a dispersion: Depending on the formulation, VINNAPAS® LL 3112 allows highly fire-resistant coatings with fire resistance class F120 to be achieved, which means heat protection for up to two hours.
