Schluter-DILEX-KSN is available with solid brass, aluminum, and stainless steel anchoring legs. All profiles feature a thermoplastic rubber movement zone.
In special cases, the suitability of a proposed type of material must be verified based on the anticipated chemical, mechanical, and/or other stresses.
The thermoplastic rubber movement zones are resistant to most chemicals commonly encountered in tile environments.
The stainless steel anchoring legs are manufactured using 304 (1.4301 = V2A) stainless steel. Stainless steel can sustain high mechanical stresses and is especially well suited for applications requiring resistance against chemicals and acids.
The solid brass anchoring legs can sustain high mechanical stresses and are resistant to most chemicals used in tiled environments. Solid brass that is exposed to air will oxidize, resulting in a natural patina. If exposed to moisture or aggressive substances, heavy oxidation and spotting may occur.
The aluminum anchoring legs must be tested to verify suitability if chemical stresses are anticipated. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminum is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and duration of exposure) may result in corrosion (aluminum hydroxide formation). Therefore, it is important to remove mortar or grout residue from visible surfaces. In addition, ensure that the profile is solidly embedded in the setting material and that all cavities are filled to prevent the collection of alkaline water.
