WACKER Expands Silaneterminated Polymers Production for AS WACKER to construct a new production line for silane-terminated polymers at its site in Nünchritz, Germany, in 2020. Silane-terminated 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.

Strengthening Specialty Chemical Products

The investment budget for the construction project is in the mid double-digit million range. The production line will go onstream in 2022. WACKER intends to expand its production capacities for hybrid polymers and to further strengthen its focus on specialty chemical products with the investment.

WACKER has manufactured silane-terminated polymers at its production site in Burghausen, Germany. Since then, the hybrid-polymer business has experienced robust growth, the company now ranking the second largest manufacturer 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 was selected on the basis of market access, availability of critical raw materials and, most importantly, production technology aspects. “We have the space for a fully integrated production line in Nünchritz, which we could even expand, should the need arise,” added Willems.

SMPs for Manufacturing High-performing Adhesives

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 (SMP) 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,” added Gnann. The alpha-silane technology helps the company in developing customized binders for a wide variety of adhesives and applications.

Applications for SMPs, which the company has marketed globally under the GENIOSIL® brand, include adhesives and sealants as well as construction, assembly and wood-flooring adhesives. Product properties like hardness, elasticity and tensile strength can be varied in a targeted manner with hybrid binders and adapted to special requirements for adhesive or sealant applications.

In addition, further hybrid polymers developed in a patented process open up numerous new application areas. These include water-repellent sealing membranes for flat roofs and balconies on the one hand, and extremely strong adhesives, grout mortars, crack-filling compounds, paints and wear-resistant coatings for concrete floors, on the other.
