A novel surface protection for wood sets new standards- Degussa launch Dynasylan® SIVO 121 at the European Coating Show

Published on 2007-04-30. Author : SpecialChem

Silanes from Degussa-the specialty chemicals group and wholly owned RAG subsidiary headquartered in Düsseldorf-have been important components in paint and coating systems for more than half a century. Dynasylan® is now the leading global brand name for functional silanes. At this year's European Coatings Show, Degussa's Aerosil & Silanes Business Unit presents to the trade a product of the latest generation: Dynaysylan® SIVO 121, a water-based wood- surface impregnating agent for the protection of weathered wood surfaces.

Water-based and solvent-free, Dynasylan® SIVO 121 repels dirt and water, but is also breathable and protects the surface from the effects of weathering. Additionally, its use hinders the growth of microorganisms, for example, on garden furniture. Dynasylan® SIVO 121 is odorless and virtually invisible after application. Whether rolled, painted, or sprayed on to the surface, it is easy to use. It is suitable for almost any wood surface, regardless of whether the wood is untreated or already impregnated, weathered or unweathered, and originally glazed, waxed, or varnished. Dynasylan® SIVO 121 does not affect the expansion and contraction behavior of the wood, and is therefore particularly suitable also for outdoor objects without ground contact.

Dynasylan® SIVO 121 is used for water repellent (hydrophobizing) treatment as well as for oil and grease repellent modification of wood surfaces. Surfaces treated in this way repel water and, thanks to a highly efficient beading effect, even prevent the adhesion of oils and greases to the wood surface and their permeation into it. A positive side-effect here is a reduction of the tendency to staining caused by adherent dirt particles that are often carried by water or oils. The exclusion of water also lengthens the life of the treated woods. Degussa estimates that, depending on the dosage, the protection will last for up to three years. Surfaces treated with Dynasylan® SIVO 121 also remain breathable and have good weathering resistance.

Dynasylan® SIVO 121 represents the latest generation of the Dynasylan® SIVO product range. These are Multifunctional Silane SystemsTM, which combine a variety of different functions in a single product. Thanks to its own research and technical service worldwide, Degussa is now in possession of a large number of exclusive patents and technologies unique anywhere in the world. This is the base from which Degussa has developed its totally unique silane systems.

Degussa's booth at the European Coatings Show (to be held between May 8 and 10, 2007) is No. 315, in Hall 1, where Dynasylan® experts will be available to inform visitors about the advantages of the new product.

Degussa-a wholly owned subsidiary of the RAG Group-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 2006 around 36,000 employees worldwide generated sales of 10.9 billion euros and operating profits (EBIT) of more than 870 million euros.
