R&D: Adhesives for tiles
Concerning adhesives for tiles, the steadiness which is described by the slip resistance is gaining importance. This special
behaviour cannot be achieved by viscosity-increasing cellulose derivatives. Only by means of rheology-enhancing starch
derivatives it is possible to adjust a sufficiently high yield point to ensure steadiness of tiles. This special property of these tile
adhesives is determined by the slip of the tiles according to standard method EN 1308.
Viscosity properties are determined via Brookfield measurement. The open time is used as an important criterion for the
workability time. This test procedure is conducted according to EN 1346. The setting performance of mortars containing starch
derivatives is determined by means of an automatic Vicat ® unit.
