Longevity e.g. with VINNAPAS dispersions for cement admixtures. In Europe, polymer binders were first used in the 1930s to improve the characteristics of mortars. WACKER was among the first to produce polymer dispersions and dispersible polymer powders for the paints and construction industries, and has been enhancing its portfolio for decades under the VINNAPAS trade name. Today, WACKER is a global market and technology leader with production sites on three continents and over 100 subsidiaries, sales offices and technical centers all over the world. VINNAPAS dispersions are co- and terpolymers based on vinyl acetate, ethylene and other monomers. Vinyl acetate-ethylene (VAE), in particular, combines technical performance with environmental benefits. The portfolio comprises many grades that are stabilized without the use of APEO-based surfactants and with low residual monomer content (< 500 ppm).

Make the Move to the technology of the future... Solvents, VOC content and plasticizers in interior paints are just examples of the topics that are under discussion concerning the environmental impact of construction materials. WACKER recognized the importance of a low VOC content decades ago and developed specialized VINNAPAS VAE copolymer dispersions. Between the late 1980s and the early 1990s, the main challenge was to reduce the VOC content without lowering performance. The result was VINNAPAS VAE copolymer dispersions that combine many advantages: Superior film formation without film-forming aids Low residual monomer content Low odor Polymerization without APEO-containing substances Low formaldehyde content More Performance with Fewer Ingredients VINNAPAS VAE dispersions provide excellent film-forming properties without the addition of coalescing agents. And they achieve this at very low temperatures of less than 5 C. At the same time, it is possible to formulate interior paints that fulfill high standards of e.g. scrub or blocking resistance. This results in a favorable cost-in-use ratio. Compliance with Strict Labels With our cutting-edge VINNAPAS VAE dispersions, the construction and paints industries are equipped to meet stringent governmental regulations, as well as the requirements of internationally recognized ecolabels and certifications, such as Blue Angel, EU Ecolabel, LEED and Green Seal. VAE dispersions are copolymers produced by the emulsion polymerization of the hard, polar monomer vinyl acetate and the soft, hydrophobic monomer ethylene. Ethylene functions as an optimal flexibilizer for vinyl acetate, which gives permanent flexibility to VAE polymers. No external plasticizer is thus necessary in VAEs. 6

Low VOC meets high PerformaNce VINNAPAS VAE dispersions meet the highest technical demands and the environmental requirements of the most stringent ecolabels in Europe, the Middle East and Africa. General Benefits High formulation versatility Produced without APEO surfactants Low to very low VOC formulations possible Production advantages through grades with a higher solids content High compatibility with slurries Excellent scrub resistance Favorable cost-in-use ratio Application Spectrum, textured coatings and plasters From matt to semigloss and gloss finishes Pastel or deep color paints Fulfilling Tomorrow s Demands Today The first modern paints were solvent-based with solvent/voc contents of up to 70%. Later, waterborne paints with a considerably lower VOC content were developed. Today, coatings with a VOC content of < 700 ppm are state-of-the-art. The challenge is to reduce VOCs without compromising performance. VINNAPAS VAE copolymer dispersions do this via hydroplasticization : water takes the role of an internal flexibilizer, enhancing the coalescence of the polymer particles. They thus exhibit excellent film-forming characteristics without the addition of coalescing agents even at temperatures well below 5 C.

General Benefits High formulation versatility Produced without APEO surfactants Low-VOC formulations possible Excellent compatibility with pigment pastes Excellent color stability Ideal workability and applicability High to very high durability High flexibility with low dirt pick-up Good water repellency Good water-vapor permeability Application Spectrum Exterior masonry paints Textured or structured coatings Silicone resin emulsion paints Silicate paints Lime paints Pastel or deep color paints Elastomeric or crack-bridging systems Combining Breathability and Low Flammability Exterior coatings are exposed to varying climatic conditions: it can be hot or cold, humid or dry in different combinations. This is accompanied by different degrees of UV radiation. VINNAPAS dispersions feature high water resistance combined with high mechanical strength, leading to outstanding exterior weathering behavior. They thus allow the formulation of coatings with a high resistance to dirt pick-up and long-lasting performance even when exposed to harsh conditions. VINNAPAS polymer dispersions based on vinyl acetate-ethylene-vinyl chloride additionally provide low flammability for flame-retardant formulations that match Fire Class B as per EN 13501-1. PRIMIS AF 1000: WACKER s Novel Acrylic Binder for High-Performance Exterior PRIMIS AF 1000 is a new binder that combines organic and inorganic components, thus providing a completely new property profile. This highperformance exterior paint binder addresses two of the most pressing challenges in exterior paint formulations: dirt pick-up and color stability. By greatly enhancing these two properties, PRIMIS AF 1000 ensures bright and good-looking facades for extended periods of time. 12

FireProof solutions Intumescent & Fire-Resistant When in contact with fire, intumescent (swelling) coatings based on VINNAPAS dispersions burn to a firm foam with extremely low thermal conductivity, protecting steel beams, for example, for a predictable period of time. Fire-resistant paints based on vinyl-chloride-containing VINNAPAS terpolymers improve the fire-retardant effectiveness based on the self-extinguishing properties of chlorine. General Benefits Excellent foam development that provides high expansion factors for coatings with a low dry film thickness (DFT) Good adhesion to steel beams Excellent compatibility with intumescent coating additives High shelf life of final intumescent coatings even under difficult climatic conditions Manufactured without APEOs or plasticizers Low amount of VOC and very low amount of formaldehyde Application Spectrum Fire-resistant, water-based paints or systems Intumescent, water-based paints or systems VINNAPAS EZ 3112 Intumescent fire protection coatings are used to protect steel girders in the event of a fire. The coating is usually applied one to four millimeters thick and, when subjected to heat, foams to tens of hundreds of times its original thickness, protecting the steel girders against the heat of the fire for a defined period. They thus retain their strength for longer. VINNAPAS EZ 3112, based on vinyl acetate-ethylene-vinyl ester terpolymers, shows particularly pronounced foaming and expansion, as well as long-term foam stability. At the same time, the adhesion and strength of the intumescent coatings improve, so that the protective layer firmly adheres to the substrate and forms a heat barrier for a limited period. Without the binder, the foam layer would be too brittle and would have inadequate adhesion to the steel substrate. High-rise buildings, which will be a common feature of tomorrow s megacities, are getting taller and taller. The steel skeletons of these constructions must be protected against fire. Otherwise, they could bend and collapse within five to ten minutes. 14

the Basis for Quality VINNAPAS dispersions provide primers with the necessary properties for the next layer to function properly. General Benefits Good impregnation due to high penetration into pores Excellent barrier properties Low and uniform absorbency Good adhesion of emulsion paints and coatings even on critical substrates High compatibility with different substrates Good consolidation of construction surfaces Bridging of small cracks Application Spectrum Adhesion-promoting layer Equalization of low absorption properties Barrier layer for migration protection Construction surface consolidation Stain blocking/resistance Ideal for Many Applications Most buildings are built one layer upon the next. Primers are essential to ensure the long-term durability of each subsequent layer, either for interior or exterior applications. Under outdoor conditions, primers require high water repellency and good barrier properties, which is where hydrophobic dispersions such as VINNAPAS are needed. Dispersions with small particles penetrate well into the surface and consolidate open-pore substrates such as concrete, cement and gypsum plasterboards and control the absorbency of the substrate.
