Sikaflex - 118 Extreme Grab
Description
<p>PRODUCT DESCRIPTION Sikaflex®-118 Extreme Grab is a 1- part construction adhesive with very high initial grab which bonds most construction material substrates. Internal and external use. </p><p>USES An adhesive to bond most construction components and materials such as: </p><p>▪ Concrete </p><p>▪ Masonry </p><p>▪ Most stones </p><p>▪ Ceramic </p><p>▪ Wood </p><p>▪ Metals </p><p>▪ Glass </p><p>▪ Mirrors CHARACTERISTICS / ADVANTAGES </p><p>▪ Very high initial grab </p><p>▪ Fixing of heavy objects without temporary fixation </p><p>▪ Good workability </p><p>▪ Very low emissions </p><p>▪ Adhesive-sealant with CE marking ENVIRONMENTAL INFORMATION Conformity with LEED v4 EQc 2: Low-Emitting Materials </p><p>▪ VOC emission classification GEV-EMICODE EC 1PLUS </p><p>▪ VOC emission classification of building materials RTS M1 </p><p>▪ Class A+ according to French Regulation on VOC emissions </p><p>▪ APPROVALS / STANDARDS CE Marking and Declaration of Performance to EN 15651-1 - Sealants for non-structural use in joints in buildings - </p><p>Facade elements: Class F EXT-INT CC 20HM</p><p>APPLICATION INSTRUCTIONS SUBSTRATE PREPARATION </p><p>The substrate must be sound, clean, dry and free of all contaminants such as dirt, oil, grease, cement laitance, old sealants and poorly bonded paint coatings which could affect adhesion of the adhesive. </p><p>For optimum adhesion and critical high performance applications the following priming and/or pre-treatment procedures shall be followed: Non-porous substrates Aluminium, anodised aluminium, stainless steel, galvanised steel, powder coated metals or glazed tiles, slightly roughen surface with a fine abrasive pad. </p><p>Clean and pre-treat using Sika® Aktivator-205 applied with a clean cloth. </p><p>Before bonding / sealing, allow a waiting time of > 15 minutes (< 6 hours). </p><p>Other metals, such as copper, brass and titanium-zinc, clean and pre-treat using Sika® Aktivator-205 applied with a clean cloth. After a waiting time of > 15 minutes (< 6 hours), apply Sika® Primer-3 N applied by brush. Allow a further waiting time of > 30 minutes (< 8 hours) before bonding / sealing. </p><p>PVC has to be cleaned and pre-treated using Sika® Primer-215 applied with a brush. </p><p>Allow a waiting time of > 15 minutes (< 8 hours) before bonding / sealing. </p><p>Porous substrates Concrete, aerated concrete and cement based renders, mortars and bricks, prime surface using Sika® Primer-3 N applied by brush. Before bonding / sealing, allow a waiting time of > 30 minutes (< 8 hours). </p><p>For more detailed advice and instructions contact Sika Technical Services. </p><p>Note: Primers are adhesion promoters and not an alternative to improve poor preparation / cleaning of joint surfaces. </p><p>Primers also improve the long term adhesion performance of a sealed joint. </p><p>APPLICATION METHOD / TOOLS Bonding Procedure After the necessary substrate preparation, prepare the end of the cartridge before or after inserting into the sealant gun then fit the nozzle. </p><p>Apply in triangular beads, strips or spots at intervals of a few centimetres each. </p><p>Use hand pressure only to fix the components to be bonded into position before the adhesive is allowed to skin. </p><p>Incorrectly positioned components can easily be unbonded and repositioned during the first few minutes after application.</p><p>If necessary, use temporary adhesive tapes, wedges, or supports to hold the assembled components together during the initial curing time. </p><p>Fresh, uncured adhesive remaining on the surface must be removed immediately. </p><p>Final strength will be reached after complete curing of Sikaflex®-118 Extreme Grab, i.e. after 24 to 48 hours at +23 °C, depending on the environmental conditions and adhesive layer thickness.</p><p>CLEANING OF TOOLS Clean all tools and application equipment immediately after use with Sika® Remover-208. </p><p>Once cured, hardened material can only be removed mechanically. For cleaning skin use Sika® Cleaning Wipes-100. FURTHER DOCUMENTS </p><p>▪ Pre-treatment Chart Sealing and Bonding LIMITATIONS For good workability, the adhesive temperature shall be +20 °C. </p><p>▪ Application during high temperature changes is not recommended (movements during the curing). </p><p>▪ Before bonding, check adhesion and resistance of paints and coatings by carrying out a trail. </p><p>▪ Sikaflex®-118 Extreme Grab can be overpainted with most conventional water-based coating and paint systems. However, paints must first be tested to ensure compatibility by carrying out preliminary trials. </p><p>The best over-painting results are obtained when the adhesive is allowed to fully cure first. Note: non-flexible paint systems may impair the elasticity of the adhesive and lead to cracking of the paint film. </p><p>▪ Colour variations may occur due to exposure to chemicals, high temperatures and/or UV-radiation (especially with the colour shade white). However, a change in colour is purely of aesthetic nature and does not adversely influence the technical performance or durability of the product. </p><p>▪ Always use Sikaflex®-118 Extreme Grab in conjunction with mechanical fixings for overhead applications or heavy items. </p><p>▪ For very heavy components provide temporary support until Sikaflex®-118 Extreme Grab has fully cured. </p><p>▪ Full surface applications / fixings are not recommended since the inner part of the adhesive layer may never cure. </p><p>▪ Before using on natural stone, contact Sika Technical Service. </p><p>▪ Do not use on bituminous substrates, natural rubber, EPDM rubber or on any building materials which might leach oils, plasticizers or solvents that could attack the adhesive. </p><p>▪ Do not use on polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE / Teflon), and certain plasticised synthetic materials. Preliminary trials should be carried out or contact Sika Technical Services. </p><p>▪ Do not use for glass bonding if the bond line is exposed to sunlight. </p><p>▪ Do not use for structural bonding. Do not expose uncured Sikaflex®-118 Extreme Grab to alcohol containing products as this may interfere with the curing reaction.</p>
