Poured asphalt: • Asphalt quality:
Cleaning: Work tools must be carefully cleaned immediately after use, with ASO-R001 or acetone. Packaging: 10 litre Component A and component B are supplied at a predetermined mixing ratio. Storage: frostfree, cool and dry ≥ +10°C to +25°C, 18 months in the original unopened packaging. Use opened containers promptly.
Metallic areas: • Surface purity steel: min. SA 2½ Note: The structural requirements for forming the joints must be commensurate with DIN 18 540 and IVD data sheet No.1 and checked on site. In particular, the joint width must be measured so that the total movement of the joint is not greater than that suitable for the sealant.
Substrate preparation: The contact surfaces to be treated must be: • dry, sound, load bearing and have a good key. • free from separating and adhesion reducing substances e.g. dust, laitance, grease, oil, plasticizers, rubber marks, rust, paint residues and similar. • protected against moisture penetration from the rear.
Where vehicular traffic will traverse the building component, the joint edges are to be prepared by bevelling prior to extruding the sealant. Do not fill the bevel. Where there will be high exposure to water pressure, it is recommended that the backing strip ASO-SR is supported by a supplementary, stable material (e.g. adding sand and/or polystyrene strips).
Substrate preparation is to be carried out with reference to DIN EN 14879-1:2005, 4.2 following.
Product preparation: Component A (resin) and component B (hardener) are supplied at a pre-determined mixing ratio. Add component B to component A. Ensure that the hardener completely drains from its container. Blending of the two components is to be carried out with a suitable rotary stirrer at approx. 300 rpm (e.g. drill with paddle/can mixer). It is important to also stir at the sides and the bottom so that the hardener is evenly dispersed. Keep stirring until the mixture is homogenous (free from streaks); mix time approx. 8 minutes. During the mixing process the material temperature should be approx. +15°C. Do not use the mixed material directly from the packaging. Decant the mass into a clean mixing bucket and thoroughly stir through again.
Dependent on the condition of the substrate to be treated, use suitable mechanical preparation methods, e.g. scabbling, planing, grit blasting etc, with which a textured, load-bearing surface is achieved. Appropriate to each particular substrate, the following criteria are also to be fulfilled: Cement-based areas: • Concrete quality: • Screed quality: • Tensile adhesion strength: • Age:

Application method/consumption: 1. Place the backing strip ASO-SR into the prepared joint void. Ensure that the backing strip will not become damaged. 2. When using in tramway track construction (with rail side elements as the base of the joint), it is also necessary to ensure that a three sided bond is prevented by laying strips of polythene at the base of the joint. 3. Priming the joint edges: prime highly absorbent mineralbased joint edges beforehand with INDU-Primer-S, nonabsorbent joint edges with INDU-Primer-N and asphalt contact areas with INDU-Primer-A. 4. Before implementing the sealing process, protect the joint edges with adhesive tape. 5. Filling with the sealant: The homogenously mixed sealant is poured into the joint without air and smoothed off. Rising air bubbles are to be removed within the pot life by lightly brushing with a smoothing stick or a soft flat brush.
Important advice: • Higher temperatures shorten the pot life. Lower temperatures increase the pot life and setting time. Material consumption is also increased at lower temperatures. • Colours: Minor colour variations caused by different production batches and raw material fluctuations are unavoidable. Please allow for this with coating and sealant work. Carry out adjoining work with material from the same production batch (same batch number on the packaging). • The bond between individual coats can be heavily impeded by the penetration of moisture and contamination between the individual coats. Coating and sealing work requires a substrate temperature of at least 3°C above the dew point temperature. • If there is a long down after application of the primer, then the primed surface is to be well cleaned and thoroughly abraded. Afterwards re-apply the primer. • The surface of the sealant must be protected from moisture for approx. 4 – 6 hours after application (e.g. rain, melt water). • Fresh sealant can be applied to cured, thoroughly cleaned sealant without the need to carry out supplementary priming of the existing sealant. • Consumption quantities given are values determined by calculation without additions for surface roughness or absorption, levelling or residues in the containers. We recommend adding a calculated safety factor of 10% to the computed consumption quantities. • Applications, which are not clearly mentioned in this technical data sheet may only be implemented after consultation with and written confirmation from the technical service department of SCHOMBURG. • Cured product residues can be disposed of using waste disposal code AVV 150106.
The material consumption of INDUFLEX-PS can be calculated as follows: Joint width (mm) × fill depth of the sealant (mm) = required quantity of sealant (ml) per linear metre of joint. Example: Joint width 20 mm and fill depth 17 mm = 340 ml/lm sealant required. During the curing time, early stresses (e.g. very high temperature differences; direct contact with vehicular traffic) must be prevented.

All data has been determined under laboratory conditions at +20°C. Deviations are possible due to high temperatures, local factors and environmental conditions. Slight optical surface changes or minor swelling, which does not affect the functionality of the sealant, cannot therefore be precluded. Where doubt exists, we recommend that project related suitability trials are carried out. It is therefore to be ensured that where liquid escapes, it is removed as quickly as possible from the surface of the sealant and within the maximum permissible impingement time.
