MOSCOW (MRC) -- The Munich-based chemical company Wacker has presented new highly efficient coating compounds for the paper and film coating industry. The focus is on four new silicone polymers for industrial label applications, reported the producer on its site.
They are solvent-free and cure extremely quickly, which is why they are ideal for cost-effective release coatings. The products belong to the new DEHESIVE SFX product family.
Release coatings with silicone polymers of the new DEHESIVE SFX product family are ideal for high-speed labeling machines. The new silicone grades are very cost-efficient. With their help, the proportion of platinum catalyst in the coating system can be lowered by up to 60 percent compared to conventional silicone systems.
The new products are solvent-free and cure by a platinum-catalyzed addition reaction. Due to their high reactivity, the silicone polymers require very little catalyst to cure fully. Compared to conventional coating systems, platinum savings of up to 60 percent are possible with the DEHESIVE SFX system. This makes production considerably more cost-effective for release-paper and label manufacturers. In addition, the properties of the new silicone polymers can be optimized specifically for fast labeling processes.
As MRC wrote previously, 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.
