Technical data sheet INDUFLEX-PU Substrate quality class
Preparing the details In the case of building components which vehicles drive on, prepare the joint edges for the casting by chamfering them with a 45° chamfer with a chamfer edge of approx. 5 mm. The chamfer must not be filled. General standard of joint width to joint depth (sealant thickness) = 1:0.8 or 1: 1.
Application Application 1. Insert a closed-cell backfill cord into the prepared joint space without damaging it. 2. Before grouting, protect the joint edge areas with adhesive tape. 3. 4. INDUFLEX-PU is applied with a suitable cartridge gun. The joint sealant must be applied free of bubbles and voids and must have complete contact with the joint edges. 5. If necessary, level the joint surface within the pot life by lightly brushing over with the smoothing wood or a soft brush using a smoothing agent. 6. Strike off the joint compound with a suitable smoothing tool, pressing on the joint edges and the backfill.
Cleaning tools Clean tools immediately after use with suitable solvent.
Storage conditions Storage Store in a frost-free, cool and dry place. At min. 5 - 25 °C for 15 months in the original canister. Promptly use opened container.
Disposal Hardened product leftovers can be disposed of in accordance with disposal code AVV 15 01 06.
Notes The indicated consumption quantities are calculated values without additions for textured surface roughness and absorbency, level compensation and residual material in the container. We always recommend a calculated safety addition of 10% on top of the calculated consumption quantities. Higher temperatures shorten the pot life. Lower temperatures increase the application and hardening times. The bonding between the individual layers can be strongly disrupted between the individual application steps due to the effects of dampness and contamination. Coating work requires a substrate temperature of at least 3 °C above the dew point temperature. INDUFLEX-PU must not be used in swimming pool areas and for sealing glass. INDUFLEX-PU may not be used on polyethylene, polypropylene, Teflon, polystyrene and bituminous substrates INDUFLEX-PU must not be painted over. Hard cleaning brushes used for mechanical cleaning can destroy the joint Slight colour differences, caused by different production batches and raw material fluctuations, are unavoidable. Neighbouring surface sections should be coated using the same production batch (same batch no. on the delivered packaging). Effects of the environment and external influences can lead to colour changes, but these have no effect on the functionality of the jointing compound. No discoloration on natural stones, please carry out tests before application Protect from the effects of dirt and moisture during the curing phase. The hardening time until full loadability is 14 days at approx. +20 °C. 80% of the final hardness, according to Shore A, is reached after 2 days at +23 °C Observe the technical data sheets of the products mentioned before starting work. Applications that have not been clearly mentioned in this technical data sheet may only be carried out after the technical service department of SCHOMBURG GmbH has been consulted, and after the said department has approved of such a course of action in writing.
