Silicone Sealants

Silicone sealants have long been recognized as vital components in building and assembly and they will remain important given the growing demand for sustainability in these industries. They are indispensable products in essentially all key industries. Their significant advantages over alternative materials include outstanding weathering and aging properties, unparalleled UV stability as well as temperature resistance. Take advantage of the proximity to WACKER as a full-portfolio supplier offering products of consistent quality in addition to various purchasing options, from the raw materials to the finished silicone sealants, all available in containers, drums, or cartridges.

ELASTOSIL^® - Finished Construction Sealants

ELASTOSIL^® silicone sealants are one-component, low-modulus products available as diverse curing systems. They are the sealants of choice in construction applications, including a wide range of connection and expansion joints as well as sanitary and other specialized sealing tasks. Irrespective of the grade of interest, most of our finished silicone sealants are available in various packaging types, such as drums, that allowing refilling. In addition, cartridges and sausages can be ordered with diverse options for private labeling and therefore the flexibility to adapt your product to suit the market channels served by your company.
