The WACKER Chemical Group has developed two new hydrophobic dispersions for waterproofing buildings at low temperatures: VINNAPAS 754 ED and VINNAPAS 764 ED. VINNAPAS 754 ED is used as an additive in two-part waterproofing membranes. It retains its crack-bridging ability at temperatures as low as ‒5°C. VINNAPAS 764 ED, on the other hand, can accomplish the same feat even at ‒20°C. The company will be presenting both products at the European Coatings Show (ECS), to be held in Nuremberg, Germany, March 28-30, 2023.
Preventing water and moisture damage is one of the most important challenges involved in the medium- and long-term upkeep of buildings. One option for protecting balconies, bathtubs and other surfaces from water penetration is to apply cementitious waterproofing membranes. Depending on the field of application, these types of waterproofing products may even perform at very low temperatures. Polymeric binders blended in during the manufacturing process provide the necessary flexibility and hydrophobicity. Additives like these can constitute as much as 30% of the waterproofing membrane.
VINNAPAS 754 ED and VINNAPAS 764 ED are terpolymers based on vinyl acetate, ethylene and vinyl ester. They are used as hydrophobic binders in two-part cements and help to bond the end product reliably and permanently, even on difficult substrates.
