V2A, material no. 1.4301 = AISI 304
V4A material no. 1.4404 = AISI 316L
The movement zone consists of highly flexible thermoplastic rubber with inserts made of a harder material.
Material properties and areas of application
The suitability of the selected profile type must be verified based on the anticipated chemical, mechanical, and/or other stresses. Schlüter-DILEX-EKSN/ -EKSB/ -EKSA with stainless steel support profiles made of material no. 1.4301 (V2A) or 1.4404 (V4A) are especially suitable for applications which, in addition to high mechanical durability, require resistance to chemical stresses from sources such as acidic or alkaline media, cleaning detergents, or de-icing salt. Depending on the anticipated chemical stresses, customers can choose between the alloy materials 1.4301 (V2A) or 1.4404 (V4A). The use of V4A is recommended if consistent exposure is expected, for example in the case of swimming pools (fresh water). Even stainless steel of quality 1.4404 is not resistant to all chemical stresses such as hydrochloric and hydrofluoric acid or certain chloride and brine concentrations. In certain cases, this also applies to seawater pools. Special anticipated stresses should therefore always be verified in advance.
Schlüter-DILEX-AKSN and -AKSA with lateral anchoring leg profiles of aluminium are sensitive to alkaline media. Cementitious materials, in conjunction with moisture, become alkaline, which may result in corrosion depending on the concentration and length of exposure (aluminium hydroxide formation). For this reason, remove mortar or grouting material immediately from all visible areas and do not cover freshly installed coverings until dry. Solidly embed the profile in the setting material to prevent alkaline water from accumulating in small cavities.
The movement zones of DILEX-KSA consist of highly flexible thermoplastic rubber. This material is UV-resistant, suitable for outdoor use, and resistant to the chemical stresses typically associated with tile coverings and has been specially treated to resist fungi and bacteria.
The insert is resistant to temperatures ranging from -60 °C to +100 °C. The synthetic rubber can be heat bonded to extend the profile length.
The tile inserts DILEX-KS/K are available in all colours for cross joints created with the movement profiles DILEX-KS.
