Invisible protection with highly visible effect Dynasylan® SIVO 121 - Degussa’s New Solvent-Free and Permeable Protective Impregnating Agent for Wood Surfaces

Published on 2006-07-31. Author : SpecialChem

Degussa AG, Düsseldorf, will shortly be launching on the market a new protective impregnating agent for wood surfaces under the brand name Dynasylan® SIVO 121. According to Dr. Burkhard Standke of Degussa Technical Service, Dynasylan® SIVO 121 has several advantages over commonly available commercial products: "The water- and dirt-repellent properties are particularly impressive. This means that attack of the wood surfaces by microorganisms such as molds is significantly reduced. Dynasylan® SIVO 121 is suitable for both untreated and impregnated woods. In contrast to the oils and waxes currently used for the purpose, it is odorless. It is also non-toxic and solvent-free, and therefore not subject to labeling regulations under German chemicals legislation." Standke adds: "The lower thickness of the applied layer means that the product is virtually invisible. But it has extraordinarily high weathering resistance and, depending on the concentration, is effective for up to three years."

Degussa, the global market leader in specialty chemicals, will supply the new water-based impregnating agent initially to producers and formulators of wood preservatives and to wholesale manufacturers of, for example, garden furniture. Dynasylan® SIVO 121 is suitable for both untreated and impregnated woods as well as for weathered surfaces of originally glazed, waxed, or varnished woods. The new wood preservative from Degussa does not affect the expansion and contraction behavior of the treated wood. This makes it suitable also for woods without ground contact in exterior applications.

Organofunctional silanes with the Dynasylan® brand name are used in a broad range of applications. In addition to the application described here, they are used, for example, in adhesives and fillers, in foundry resins, in insulation materials, as additives in paints and coatings, and in the electronics industry. In addition, Protectosil®, another product group from the Silanes Business Line, protects buildings against graffiti and saves on the considerable cost of its removal.

The Aerosil & Silanes Business Unit employs a total of about 1,900 people at nine sites in Europe, the U.S., and Asia. Based on 60 years of experience, the products of the Aerosil & Silanes Business Unit occupy leading global positions. To ensure that this remains so, research focuses on continual development of customer-specific solutions; innovative products for building protection, electronics, and high-performance ceramics open up new fields of application.

Degussa is the global market leader in specialty chemicals. Our business is creating essentials - innovative products and system solutions that make indispensable contributions to our customers' success. In fiscal 2005 around 44.000 employees worldwide generated sales of 11.8 billion euros and operating profits (EBIT) of 940 million euros.
