Wacker Introduces GENIOSIL® XL 70, an Arylalkoxysilane Monomer for Silane-curing Adhesive

Published on 2014-12-03. Author : SpecialChem

Munich -- Munich-based chemical company WACKER is expanding its product range of functional silanes with a new arylalkoxysilane monomer. Marketed as GENIOSIL® XL 70, this additive is designed as a water scavenger for silane-curing adhesive and sealant formulations. It is particularly suitable for products that must avoid unpleasant odors when applied. Due to its high flash point, the additive is also easier to store and handle. The new water scavenger is compatible with all GENIOSIL® silane-modified polymers and organofunctional silanes.

GENIOSIL® XL 70 is a new water scavenger developed by Munich-based WACKER for silane-curing adhesive and sealant formulations. It is particularly suitable for low-odor, liquid waterproofing systems.

GENIOSIL® XL 70 is a clear, colorless, low-viscosity silane which belongs to the arylalkoxysilane group. Unlike conventional water scavengers for silane-curing adhesives and sealants, the liquid has only a very faint odor. Consequently, the water scavenger is ideal for adhesives and sealants used over large areas. Compounders can formulate products such as parquet adhesives and liquid water-proofing systems that do not create odors with the additive and are in line with increasingly stringent occupational health and safety regulations.

Additionally, GENIOSIL® XL 70 has a much higher flash point than conventional water scavengers, which is 96 °C as per ISO 3679. This is an advantage for processors. For example, less effort is required to store and process the additive.

As silane-curing adhesives and sealants react with water, water scavengers are an essential component in such products. They protect the polymers from moisture inherent to a formulation via fillers and other ingredients. Moreover, water scavengers ensure that the product can be used without restriction throughout its given minimum shelf life. The required dosage of GENIOSIL® XL 70 depends on the formulation components and the desired shelf life of the end product.

WACKER is a globally-active chemical company with some 16,000 employees and annual sales of around €4.48 billion (2013). WACKER has a global network of 25 production sites, 21 technical competence centers and 52 sales offices.
