1 Surface Protective Systems Technical information TI 374 Expansion joint filler, especially suitable for the corrosion protection Base Polyurethane Material Group Mortars, Jointing Materials Description 2-component expansion joint filler in horizontal expansion joints up to 1 % slope Use Expansion joint filler in horizontal expansion joints up to 1 % slope. Note: Expansion joints must always be regarded as maintenance-requiring parts. Therefore, they must be checked regularly and repaired as required. For more information, see Technical Information Joint Definition. Properties thermal resistance up to 60 C (wet exposure), up to 80 C (dry exposure) Colour: light grey Physical Data Property (unit), Test method Density (g/cm³), DIN EN ISO , ASTM D Elongation at tear (%), DIN EN ISO 527, ASTM C Value Shore A hardness, DIN 53505, ASTM D Tensile Strength (MPa), DIN EN ISO 527, ASTM C max. allowable deformation (%) 19 Chemical Resistance For the full chemical resistance list see the chart at the end of this document. Please contact our application engineering for approval of the project-specific possible application. Substrate Concrete / screed Refer to DIN EN as well as to STEULER-KCH-Formsheet 010. To attain a sufficient adhesive tensile strength, the substrate is generally to be pretreated in such a way that it is free of cement slurry, cement skin, loose and crumbly particles, structure imperfections and separating substances. Residual moisture content of concrete substrate must not exceed 4 %. The substrate should have a temperature of approx C. Moisture During application, the substrate must be kept absolutely dry. Uncured material has to be protected from any kind of moisture (condensation, fog, precipitation or other water source).uncured material has to be protected from any kind of moisture (condensation, fog, precipitation or other water source). Distance to dew point has to be at least 3 K, at a relative humidity of above 70 % at least 5 K. PAGE 1 / 5 Telephone: 49 (0) p Fax: 49 (0) p sales-oss@steuler-kch.de p

2 Packaging / Shelf life The products shall be stored and transported in a cool and dry place. Shelf life is specified for a storage temperature of 20 C. Higher temperatures reduce, lower temperatures increase the shelf life. Component Colour approx. Item number Package Content Shelf life Oxydur-CD-Solution Bucket 3.75 kg** 24 months Oxydur-CD-Solution Bottle 1.25 kg** 6 months Oxydur-Accelerator CD Bottle 0.04 kg** 12 months ** predosed packaging Oxydur-CD-Solution 1 must be stored at about 5 C! Mixing Ratio / Consumption Part by weight Part by volume Oxydur-CD-Solution Oxydur-CD-Solution Consumption kg / liter mortar mass Optional*: Oxydur accelerator CD 0.04 The surfaces to be bonded have to be primed with Oxydur K 425 (see TI 102). *at temperatures of C Waiting Times Waiting times between the layers and and subsequent systems depend on the temperature and are as follows: 5 C minimum 5 h maximum 36 h 20 C minimum 3.5 h maximum 24 h 30 C minimum 1.5 h maximum 12 h Further information can be found in VA 102. Working Times The working times depend on the temperature and are as follows: Oxydur K C approx. 30 minutes 20 C approx. 20 minutes 30 C approx. 10 minutes C (with accelerator) approx. 15 minutes 20 C approx. 30 minutes 35 C approx. 15 minutes Curing times The joints achieve full chemical and mechanical resistance after at least 7 days at 20 C. Light loads like foot traffic can take place after 36 hours. Safety measures Mix and apply material only in well ventilated areas. Provide ventilation suited to the conditions when working in pits or tanks. Do not smoke! Do not expose materials to heat or open flame. This applies in particular to welding works (weld beads). Avoid direct contact of the material with the skin. Wash hands with soap and water; do not clean the skin with solvents. Use barrier soap and protective creams on exposed skin areas. In all other respects comply with the relevant regulations for prevention of accidents. PAGE 2 / 5 Telephone: 49 (0) p Fax: 49 (0) p sales-oss@steuler-kch.de p
