Polyurethane <br />Colour: grey <br />Consistency: thixotropic <br />Density: <br />approx. 1.30 g/cm3</p> <p>Substrate Temperature: between +5 °C and + 35 °C <br />Ambient Temperature: between +5 °C and + 40 °C <br />Skin formation *): <br />60 – 90 minutes <br />approx. 2 mm/24 h <br />Curing rate *): <br />Joint Dimensions: min. 10 mm/max. 40 mm, <br />dependant on mechanical <br />loading <br />*) <br />Working Time : <br />approx. 2 hours <br />Shore A hardness *): approx. 35 after 28 days <br />Tear Strength: <br />approx. 8 N/mm <br />*) <br />Tension : approx. 0.6 Mpa/ <br />100% elongation <br />Elongation at Break *): approx. 700% <br />Elastic Recovery: <br />>80% <br />Approved total <br />deformation: <br />approx. 25 % of joint width <br />Service Temperature: between -40° C and +80° C <br />Packaging: 600 ml sausages <br />(6 sausages = 1 carton) <br />Storage: Frost-free, cool and dry, 15 <br />months in the original unopened <br />packaging, between +10 °C <br />and +25 °C. Use opened <br />packagings promptly. <br />*)</p> <p>These values relate to +23° C and 50% relative humidity.</p> <p>Surface preparation: <br />The contact surface to be treated must be: <br />• dry, firm, sound and have a good grip <br />• free from separating and adhesion inhibiting <br />substances such as dust, laitance, grease, oil, <br />rubber marks, paint residues and similar <br />Design requirements: <br />The constructive prerequisites of the joint must be <br />according to the IVD leaflet Nr.1. The joint width must <br />be calculated so that the cumulative motion of the joint <br />is not higher than suitable for the sealing material.</p> <p>1/2</p> <p>25/17</p> <p>In areas where the joints will be subjected to vehicular <br />traffic, joint edges must be prepared for application <br />by saw-cutting/milling. The joint should be filled to just <br />below the saw-cut (chamfers should not be filled). For <br />high water pressure load, e.g. in sewage and waste <br />water treatment plants, an additional stable back filling <br />should be installed below the backer rod (e.g. sand <br />filling and /or Styrodur-strips). <br />Mixing Instructions: <br />INDUFLEX-PUis delivered ready-to-use in 600 ml <br />sausage packs, and is applied with a suitable <br />applicator gun. Using a suitable smoothing tool press <br />the dispensed joint material into the joint flanks and <br />back filling profile. When required the joint surface can <br />be smoothed, within the working time, with a smoothing <br />wood or soft brush by using smoothing liquid. <br />Method of Application/Consumption: <br />1. Prepare the joint void by blocking with a suitable <br />closed cell backing strip. In the process, ensure that <br />the backing strip does not become damaged. <br />2. Prime the joint edges. Pre-treat highly absorbent <br />mineral-based joint edges with INDU-Primer-S, nonabsorbent joint edges with INDU-Primer-N. <br />3. Before applying sealants, protect joint flanks from <br />contamination with a self adhesive strip. <br />4. Apply the joint sealant: <br />INDUFLEX-PU is installed with a suitable caulking gun.</p> <p>Important advice: <br />• Bonding of subsequent coats (layers) to each other <br />can be negatively affected by the presence of <br />moisture and dirt. <br />• If a longer waiting time occurs after applying the <br />primer, it must be thoroughly clean and roughened, <br />followed by a fresh application. <br />• Do not use INDUFLEX-PU in swimming pools. <br />• Granite and natural stone substrates can generally be <br />treated like concrete surfaces. <br />• Do not paint over INDUFLEX-PU. <br />• Do not apply onto bituminous substrates, EPDM <br />and natural rubber or building materials which might <br />bleed oils, plasticizers or solvents, which could attack <br />the sealant. <br />• Avoid contact of the uncured material with isocyanate <br />substances, e.g. alcohol containing cleaners). <br />• Applications that are not clearly explained in this <br />technical data sheet may only be carried out after <br />consultation with and written confirmation from the <br />Technical Services Department of SCHOMBURG. <br />Please observe a current valid EU safety data sheet!</p> <p>Consumption of INDUFLEX-PU: <br />Example: <br />Joint dimension: <br />10 mm joint width and 10 mm filling depth <br />= 6.0 m per 600 ml sausage. <br />During the curing time early loads are (e.g. very high <br />temperature differences; Traffic loads with immediate <br />contact) exclude.</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
