WACKER Presents Novel Polymer Binders and Silicones for Paints, Coatings, Construction, Packaging and Adhesives Applications

At the European Coatings Show (ECS) in Nuremberg from March 19 to 21, 2013, WACKER is showcasing numerous innovations for the paints and coatings as well as for the construction, packaging and adhesives industries. The portfolio ranges from new silicone resins and polymeric

binders for high-quality exterior and interior paints and plasters to cyclodextrins as environmentally-friendly process auxiliaries. A new dispersion for intumescent coatings enables steel girders to remain stable for longer in the event of a fire, and a novel silicone resin emulsion permits the formulation of solventfree heat-resistant protective coatings for machine parts, pipes or ovens. Innovative polymer binders allow for water-permeable drainage concrete, low-emission self-leveling flooring compounds and particularly hydrophobic grouts and plasters. Novel

surface coating resins are ideally suited for heat-sealable packaging systems and for printing inks in sterilizable food packaging. Hybrid polymers for high-strength structural adhesives and a dispersion for difficult-to-bond surfaces round out WACKER’s ECS program.

On a floor space totaling 230 square meters, the Munich-based WACKER Group is showcasing its expertise in the paints and coatings,

construction, packaging, adhesives and printing inks industriesat the ECS 2013. Around 60 technical experts will be on hand for informative

discussions with existing and prospective customers. Another WACKER booth in the same hall will further provide visitors with details about the 75th anniversary of VINNAPAS® dispersions.

Versatile Solutions for Paints and Coatings

The novel silicone resin emulsion SILRES® BS 1303 is suitable for formulating coatings with moderately hydrophobic surfaces, but does

not show pronounced surface hydrophobicity. Further, the product prevents pinholing of the plaster. The new VINNAPAS® LL 3019 dispersion

is a versatile binder for high-quality paints and plasters, whether for outdoor applications with high color stability or for lowemission indoor paints (VOC < 1g/l). A sustainable and environmentally friendly alternative for many applications in the paints and coatings industry offers the cyclodextrin technology: The ring-shaped, biodegradable molecules can be used as a process auxiliary in polymerization, for selective modification of thermal stability or as a rheology-control additive.

Industrial Coatings for Heat and Fire Protection

For more safety in the event of a fire, WACKER presents the novel polymer dispersion VINNAPAS® LL 3112 as a binder for intumescent coatings. These special fire-protection coatings encase steel girders, allowing the load-bearing structures of a building to remain stable for longer in case of a fire. The new dispersion now enables highly fireresistant coatings with fire resistance class F120 to be achieved (heat protection for up to 120 minutes). For heat protection of pots, pans, water boilers or ovens, WACKER introduces the silicone-resin emulsion SILRES® MPF 52E: The new binder component significantly improves the heat resistance of binders and allows low-solvent or even completely solvent-free coatings to be formulated that do not require classification as hazardous substances.

Polymer Binders for Construction and Concrete Applications

For the first time, WACKER is showcasing the new ETONIS® 260 for drainage concrete for road surfacing in railway tunnels durable yet

water-permeable. This enables rescue vehicles and fire engines to get to the scene of an accident inside a tunnel quickly and without any problems. Furthermore, it facilitates the transport of moisture from the tunnel, significantly reduces the formation of puddles or backed-up water and makes the surface more durable overall. WACKER is also presenting the new VINNAPAS® 5111 L, a VOCreduced powder for the formulation of self-leveling flooring compounds that conform to strict eco-labeling requirements, such as EMICODE® EC1+ or Blue Angel. With its VINNAPAS® LL 5518 H, WACKER is introducing a particularly hydrophobic novel dispersible polymer powder for applications in damp rooms or outdoors. And with GENIOSIL® WP, waterproofing membranes for flat roofs, balconies and terraces can be formulated without the use of solvents.

Surface Coating Resins for Packaging and Printing Inks

The novel surface coating resin VINNACOAT® LL 8100 allows effective sealing of aluminum foils to non-polar plastics such as polystyrene, polypropylene and polyethylene. Thanks to the polymer’s inherent elastic properties, no additional plasticizers are generally required in the formulation. That makes it particularly suitable for heat-sealable packaging systems, for instance for yogurt lids or water and juice cups. Specifically for printing inks in sterilizable food packaging,WACKER has developed the new VINNOL® H 5/50 A: The surface coating resin is both taste- and odor-free, adheres strongly to a wide range of polymer substrates and offers high pigment compatibility. Additionally, it complies with numerous food-contact regulations.

Complex Adhesives Applications

For high-strength structural adhesives, WACKER presents its hybrid polymers of the GENIOSIL® XB product range: Based on alpha-silane technology, they cure on contact with atmospheric moisture to form thermosets and achieve the high Shore-D strength needed for structural

adhesives. They also have no known health risks, meet high technical requirements and give manufacturers wide scope for formulation. For exceptional adhesion on difficult-to-bond surfaces, WACKER shows VINNAPAS® EP 8010: The dispersion reliably and permanently bonds paper to challenging surfaces such as polyvinyl chloride (PVC), polyester or polystyrene. It is also characterized by outstanding heat resistance and very high setting speed. The dispersion is thus ideal for high-performance paper and packaging applications, but also for further areas, for instance in laminated products for car interiors.
