Water Scavenger targets silane-curing adhesives and sealants.

Press Release Summary:



Consisting of arylalkoxysilane monomer with very faint odor, GENIOSIL® XL 70 Additive is suitable for products that must avoid unpleasant odors when applied. Clear, colorless, low-viscosity silane has flash point of 96°C as per ISO 3679. As silane-curing adhesives and sealants react with water, product protects polymers from moisture inherent to formulation via fillers and other ingredients. Water scavenger also ensures that product can be used without restriction throughout minimum shelf life.

WACKER Develops Water Scavenger for Silane-Curing Adhesives and Sealants



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 silanecuring 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 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 waterproofing 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.
