Wacker announces investment in new production line for silicone specialties at Nünchritz site


The Munich-based chemical company Wacker announced that it will begin construction on a new production line for silane-terminated polymers at its site in Nünchritz, Germany, this year. Such hybrid polymers are used as binders for formulating high-quality adhesives and sealants, liquid waterproofing systems and environmentally friendly wood-flooring adhesives, among other applications. The investment budgeted for the construction project is in the mid double-digit million range. The production line will go onstream in 2022. The company intends to significantly expand its production capacities for hybrid polymers and to further strengthen its focus on specialty chemical products with this investment. As per the press release, the company’s hybrid-polymer business has experienced robust growth and Wacker is now among the largest manufacturers of silane-terminated binders for adhesives and sealants.

“Given the obvious rise in demand for such products, expanding our production capacity for hybrid polymers was a logical decision,” said Executive Board member Auguste Willems. The location for the capacity expansion is said to have been selected on the basis of market access, availability of critical raw materials and production technology aspects. “We have the space for a fully integrated production line in Nünchritz, which we could even expand, should the need arise,” noted Willems.

Hybrid polymers rank among the most important growth fields for Wacker Silicones at present. “Our innovative alpha-technology based silanes are used in the manufacturing process,” said Robert Gnann who heads the company’s silicones business division. “Hybrid polymers have a unique property profile. That’s why they are used for formulating particularly high-quality and high-performance adhesives and sealants. WACKER has established a unique selling point worldwide with its alpha-silane technology.”

Silane-modified polymers enable the manufacture of environmentally friendly adhesives. “The sustainability aspect is steadily gaining traction with the formulation of adhesives and sealants as well. This is what attracts manufacturers and customers alike,” commented Gnann. “The alpha-silane technology allows us to develop customised binders for an exceptionally wide variety of adhesives and applications. Demand for these kinds of adhesives will continue to increase in the coming years.”
