MOSCOW (MRC) -- Wacker Group has introduced numerous innovations for paints and coatings, and for the construction and adhesives industries, reported the company on its site.
The products will range from a novel silicone resin emulsion for water-repellent wood impregnation systems to a new series of polymeric binders for highly durable, brilliant exterior paints. Silane-terminated polymers yield high-performance adhesives that are extremely resistant to tearing yet highly elastic.
Wacker presented two solutions for modifying gypsum drywall products: a dispersible polymer powder for smooth, crack-free grout mortars and a water-repellent silicone additive. New polymer dispersions serve as excellent binders in flooring adhesives and in applications for high-quality exterior and interior paints and plasters.
New silicone resin emulsion SILRES WH provides wood with long-lasting protection against moisture and damp, as evidenced by the beading effect on impregnated wood. In contrast, the untreated wood soaks up wet immediately. By providing long-term protection, SILRES WH greatly reduces the frequency of renovating and recoating exterior woodwork.
Water and moisture can damage wood and open the door to later problems, such as fungal and insect attack - new SILRES WH silicone resin emulsion offers a long-lasting solution. The product can be used both for hydrophobic impregnation and as an additive in formulations for film-forming, pigmented wood stains. Also celebrating its premier was the new PRIMIS line of binders for high-quality exterior applications. The first of these products, PRIMIS AF 1000, combines organic and inorganic components, enabling the formulation of bright and highly durable exterior paints with reduced dirt pick-up. The new VINNAPAS LL 3031 dispersion is an impressively versatile binder for high-quality paint and plaster applications - as suitable for flame-resistant renders as it is for low-emission interior paints.
Wacker also developed VINNAPAS 4800 G, a polymeric binder specially designed for gypsum-based joint fillers in modern drywall applications. In gypsum-based grout mortars, this low-emission dispersible polymer powder produces outstanding tensile adhesive strength on gypsum plasterboard and joint tape, yielding particularly smooth, level surfaces with no cracks or seams. Another drywall product that Wacker presented was a highly efficient water repellent: SILRES BS POWDER S makes gypsum-based dry-mix mortars hydrophobic. This powdery additive is virtually free of volatile organic compounds and can be quickly mixed with water without raising dust.
For industrial adhesives and waterproofing membranes, Wacker developed novel silane-terminated polymers: GENIOSIL XT allows manufacturers to produce highly elastic materials that exhibit exceptional tear strength upon curing – the binder thus offers a technically equivalent alternative to systems based on polyurethane. Wacker also introduced new VINNAPAS EF 8860 as a solution for flexible flooring adhesives. Besides exhibiting outstanding cohesion, adhesives containing this aqueous polymer dispersion also adhere well to the floor covering to be bonded. This makes this product ideal for flexible floor coverings such as carpets, PVC and linoleum.
In addition to excellent tensile adhesive strength - even after prolonged exposure to water - and outstanding crack bridging, the new VINNAPAS 4040 E dispersible polymer powder yields superb processing properties. This makes the binder ideal for formulating flexible sealing slurries for use in sewers, pipes, basements and bathrooms. VINNAPAS 8620 E, on the other hand, is particularly suitable for high-quality, low-emission tile adhesives. With this binder in the formulation, builders can reliably bond modern large-format tiles and very thin ones, as well as porcelain and natural-stone materials - even after heat, moisture, or freeze/thaw cycles.
As MRC informed earlier, in 2013, Wacker Chemie AG officially launched its new production plant for ethylene-vinyl-acetate copolymer (EVA) dispersions at its Ulsan site in South Korea. The additional 40,000 tonnes from the second reactor line increases the site's EVA-dispersion capacity to a total of 90,000 tonnes per year. The production capacity of the site has, thus, almost doubled, making the plant complex one of the biggest of its kind in South Korea.
Wacker Chemie AG is a worldwide operating company in the chemical business, founded 1914. The company is controlled by the Wacker-family holding more than 50 percent of the shares. The corporation is operating more than 25 production sites in Europe, Asia, and the Americas. The product range includes silicone rubbers, polymer products like ethylene vinyl acetate redispersible polymer powder, chemical materials, polysilicon and wafers for semiconductor industry.
