        WACKER at ABRAFATI 2017: Presents VAE Dispersions for Water-based Adhesives & Sealants

        WACKER is presenting a diverse range of new polymer- and silicone-based products for the region’s adhesive, coating and print industries at ABRAFATI 2017. 

       Alongside the VINNAPAS® EF 575 dispersion for caulks and sealants. WACKER is introducing three binders for adhesive applications and two new silicone products for industrial coatings to the South American market. The company is displaying products including the PRIMIS® SAF 9000 dispersion and concentrated anti-graffiti agent SILRES® BS 710 for the dirt-repellent treatment of surfaces. It will also present the VINNAPAS® EP 3360 binder for the formulation of low-odor interior paints and the polymer resin VINNOL® E 18/38 for printing ink.ABRAFATI is taking place in São Paulo, Brazil.

       New Binders for Adhesives and Sealants

       At this year’s ABRAFATI, WACKER is presenting the VAE dispersion VINNAPAS®EP 6420 for formulating water-based adhesives for demanding paper and packaging applications. This all-purpose VAE binder offers first class performance with nozzle applications featuring excellent running properties and no skin formation. The product displays a good balance between cohesion and adhesion, outstanding cleanability, high setting speed and good machine processability. Its optimal viscosity and high solids content combined with its high sedimentation stability – even when diluted to lower viscosities – allow VINNAPAS® EP 6420 to achieve formulations with a broad viscosity spectrum.

       For hard-to-bond substrates that require increasingly strong adhesion WACKER has developed the new VINNAPAS® EP 701K dispersion. Its high ethylene content paired with a relatively low glass transition temperature (Tg -10 °C) makes this VAE dispersion particularly flexible. Thanks to its strong bonding strength, high setting speed and good machine running properties, VINNAPAS® EP 701K is perfectly suited to laminating plastic films on coated and uncoated paper. Typical applications include paper bags, cardboard boxes, book covers or PVC (polyvinyl chloride) lamination for furniture. Since the chemical composition of VINNAPAS®EP 701K renders additional plasticizers unnecessary, adhesives with a low migration potential can be formulated with this product.

       WACKER also introduces the VINNAPAS® EF 575 dispersion for caulks and sealants to the South American market for the first time. The product is an ideal binder in sealing compounds for a range of applications, for example for joints in windows, stairs and doors, for cracks in walls and for sealing heating, ventilation and air-conditioning (HVAC) systems. With a relatively low glass transition temperature (Tg) of 0 °C, the binder based on vinyl acetate-ethylene copolymers provides sealants the flexibility they need. The VAE dispersion also adheres extremely well to aluminum as well as galvanized and stainless steel.

      GENIOSIL®XM20 and GENIOSIL®XM25 are new silane-terminated polymers that serve as binders and modify the mechanical properties – particularly the modulus – of adhesives and sealants. These products improve the bonding properties of plasticizer-free adhesives, eliminating the need for traditional plasticizers in the end product. GENIOSIL® XM 20 is an alpha-silane-terminated polyether that opens the door to plasticizer-free adhesives with exceptionally high elasticity. Typical applications include wood-flooring adhesives and all-round adhesive sealants. GENIOSIL® XM 25, a gamma-silane-terminated polyether, allows the formulation of low-modulus sealants with exceptionally high elastic recovery. Potential applications include sealants for expansion joints in buildings made of industrially prefabricated concrete parts and for connection joints between window frames and walls.

        Easy-Care, Dirt-Repellent Surfaces

       A special highlight of this year’s ABRAFATI is WACKER’s latest solutions for dirt-repellent treatments for an exceptionally wide range of surfaces. Due to its unique composition, the dispersion PRIMIS®SAF 9000 is both oil-resistant and hydrophobic, meaning it protects wall paints against many different types of stains – from coffee and red wine to colored pencils. Just adding 10–20 percent of the dispersion in relation to the main binder is enough to allow dirt to be simply wiped off the wall using a sponge.
       The new concentrated anti-graffiti agent SILRES® BS 710 is a one-part silicone rubber formulation that cures to form a silicone elastomer at room temperature and upon exposure to moisture. Thanks to the permanent, elastic, protective silicone film that it forms, graffiti can be easily washed off with water, while stickers, posters and signs can be removed effortlessly. A particular benefit of this product is that it contains no organotin compounds or oximes, and is formulated with little solvent.
