Adhesives for Ceramic Tiles and Tile Grouts
Based on many years of experience in the application, Dow offers specifically modified additives which help to reliably control fresh mortar properties, rheology and application performance as well as the final strengths and durability of tile adhesives and grouts respectively.
Solutions are based on different technologies - cellulosics, redispersible latex powders and emulsion polymers - and are being provided for ceramic tile adhesives as well as for grouts, with formulations that offer varying degrees of water retention at different temperatures, increased adhesion strength and improved cohesion, workability and flexibility. The products have been modified to respond to the changing needs and increasing performance requirements within an industry which is strongly influenced by design trends (such as the increase in use of large tiles as an example) and resulting properties. European norms set the standard for various levels of performance and the appropriate end-product quality which enables durable systems. Adhesion and bond strength must be ensured between a variety of materials and on a variety of substrates as well as under severe climatic exposure.
The performance requirements vary broadly and depend on many factors such as inside or outside application, application in wet or dry areas, substrate to which the tile will be applied, size of tiles. Also, certain tile materials are requiring specifically developed, high quality adhesives, like for instance natural-stone and composite-stone or densely sintered porcelain stoneware. Depending on these factors manufacturers may want to offer their customers tile adhesives with improved water persistence, higher bonding properties, faster drying times and other features.
