Mastic adhesive ceramic

Filled adhesives typically are designed for the construction and do-it-yourself trade. Filled adhesives consist primarily of the base polymer, fillers such as calcium carbonate or clay, solvents, surfactants, dispersants, preservatives, and thickeners. Formulations are specifically tailored for numerous end uses including brick mastics, carpet tile and continuous carpet adhesives, floor tile adhesives, ceramic tile, subflooring, and panel adhesives. 

The broad spectrum of adhesion displayed by acrylic adhesives make filled acrylics excellent candidates for bonding substrates made of cel-lulosics, leather, fabric, ceramic, foil, plastic, mietal, and various foams. Typical examples include panel and subflooring adhesives, decorative brick mastics, ceramic tile adhesives, carpet adhesives, floor tile adhesives, and contact adhesives.

Ceramic-tile adhesives are used for thin-bed applications on wall and floor, gluing tiles onto flat surfaces. Non-cementitious adhesives (mastics) are made of acrylic emulsion polymers (ca. 20%) mixed with silica sand and calcium carbonate as fillers (ca. 80%). One-component cementitious ceramic-tile adhesives are made of cement (ca. 35%), redispersible polymer powders (1-25%) and fillers, such as silica sand (Lutz Hahner, 2002). The redispersible polymer powders are made from emulsion polymers, which are spray dried. Predominantly vinyl acetate copolymers are used. 

Crete panels. In thin-bed ceramic tile applications, both cementitious adhesives (mortar) and non cementitious systems (mastics) are applied. 

Well defined test methods are available in North America and Europe for evaluating ceramic tile adhesives. Test methods used in Germany for emulsion-based mastics are described in DIN EN 1324 (adhesive shear strength) and DIN EN 1346 (correction or adjustment time). Cementbased CTA are tested by DIN EN 1348 (puU of strength) and again DIN EN 1346 (op>en time). Classification is determined for both types of adhesives by prDIN EN 12004. North American test methods and specifications for tile adhesives are described in the following American National Standards Institute (ANSI) standards ...
