Material

The Schluter-DILEX-KSBT is available with roll-formed stainless steel 304 (1.4301 = V2A), extruded brass, and extruded aluminum anchoring legs. The movement zone for all profile types consists of soft thermoplastic rubber with grip bars made of rigid rubber.

In special cases, the suitability of a proposed type of profile must be verified based on the anticipated chemical, mechanical, and/or other stresses. Schluter-DILEX-KSBT, in stainless steel, can sustain high mechanical stresses and is especially well suited for applications requiring resistance against chemicals and acids.

Schluter-DILEX-KSBT, in brass, can sustain high levels of mechanical stress and is resistant to most chemicals used in tiled environments.

Schluter-DILEX-KSBT, in aluminum, 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.

Thermoplastic rubber inserts are highly resistant to chemicals and can withstand chemical stresses typically encountered in tile coverings. The inserts are resistant to aging, weather, UV-rays, and ozone within a temperature range of -76 ºF (-60 ºC) to 212 ºF (100 ºC). Thermoplastic elastomers can be connected by welding if profiles are joined to produce longer lengths.
