This is a high-strength, marine-grade adhesive based on advanced hybrid MS polymer technology, specifically designed for structural and dynamically stressed bonding applications in the boatbuilding and maintenance industries. It offers high initial grab and anti-vibration bonding and bedding properties. It can be applied to wet or humid surfaces, has high UV and saltwater resistance, is virtually odourless and can be painted over.

These fittings can be effectively bedded and sealed with only Sikaflex®-291i or if the joint remains visible and is exposed to weathering, then use Sikaflex®-591 or Sikaflex®-295 UV. However, times have changed and so have adhesives. Increasingly, adhesives are powerful enough to do the job by themselves: we have adhesives to hold our car windscreens in place, modern aircraft use adhesives extensively for body parts and even the latest lifeboats rely entirely on adhesives to bond the rubbing strip to the hull. Dæksemner, såsom ventilatorer og dæklister, skal være vandtætte, men udsættes ikke for store træk- eller vridridninger. Diese Teile können mit Sikaflex®-291i veklebt und / oder abgedichtet werden. Bleiben die Fugen sichtbar und sind Witterungseinflüssen ausgesetzt, dann verwenden Sie bitte Sikaflex®-591 oder Sikaflex®-295 UV.Substrate: The surface material upon which the adhesive/sealant is applied to form a bond or joint. Sikaflex®-292i on levitettävissä lämpötila-alueella 10 °C - 40 °C (ympäristö ja tuote) mutta muutokset kuivumisnopeudessa ja levitysominaisuuksissa tulee huomioida. Optimaaliset levitysolosuhteet saavutetaan kun materiaalipinnan ja massan lämpötila on 15 °C ja 25 °C välillä. Product data sheets are available for each of the adhesives we tested: these varied in the amount of additional information they presented. The 3M data sheets were the most helpful. Your supplier should be able to provide you with the relevant data and safety sheets. Winches, windlasses are subject to high mechanical stresses, fans, hatches and hatch covers to low stresses. To make sure your fittings are sealed strongly we recommend the following:

The structural adhesives were much stronger, but their performance was below that specified in their product data sheets. This is because the manufacturers test just the adhesive itself; hence the failure is always cohesive.

Dæksemner som kædeplader, spil og styreruller skal absorbere meget høje dynamiske spændinger. Til dette formål skal et højt ydende produkt, Sikaflex®-292i, vores monteringslim, bruges sammen med yderligere mekanisk fastgørelse. It should be noted that our ‘best on test’ awards have been selected purely by bond strength, as our test does not indicate a product’s resistance to water ingress. However, it does show elasticity, suggesting that the Unibond Flextec FT101, Sikaflex-291i and 3M 4200FC all provide a bond which should put up with a fair amount of abuse while still being possible to release if required. Verklebung und / oder Abdichtung von Teilen, die hohen mechanischen Beanspruchungen ausgesetzt sind

Liimasauman riittävän kerrosvahvuuden varmistamiseksi suosittelemme sauman levittämistä poikkileikkaukseltaan kolmiomaisena (kts. piirros alla). Verklebung und / oder Abdichtung von Teilen, die geringen mechanischen Beanspruchungen ausgesetzt sind Ankerspil er udsat for høje mekaniske belastninger. Ventilatorer, luger og lugedæksler med lave belastninger. For at sikre, at dine beslag er tæt forseglet, anbefaler vi følgende:

Tensile stress: The force is perpendicular to the cross-sectional area under load. Products on test:

There are a variety of adhesive products on the market, some designated specifically for the marine market and many more available from local DIY stores or builders’ merchants. Stress: A comparative measure of the strength of a material. The maximum force is divided by the original cross-sectional area that is subjected to the force, giving load per unit area. A good bond: this will vary, depending upon whether the application is permanent or will require dismantling Disse emner kan effektivt limes med kun Sikaflex®-291i eller Sikaflex®-591, men hvis samlingen forbliver synlig og er udsat for UV-lys, vind og bølger, skal du fuge med Sikaflex®-591 eller Sikaflex®-295 UV.

Tjek forbehandlingsoversigten for behandling af underlag før limning, og følg processen i henhold til applikationsguiden. The sealant performed about averagely for the non-structural adhesives. Failure for the metals was adhesive, while the acrylic and glassfibre were 50/50 cohesive/adhesive. We also tested the shear specimens with mSEAL 295 after first abrading them with 400-grit wet and dry. The results showed a variable improvement in grip (see chart), with the aluminium showing the biggest gain from abrasion before application. AquaSeal mBond 395 Cohesive failure: The adhesive/sealant fails before the adhesive releases from the substrate – this usually gives a higher strength value than through adhesive failure. Shore A hardness: Hardness tests involve pushing an object, eg a steel ball, against the material’s surface with a specified force. The amount of penetration gives a measure of the hardness. The Shore A scale is used to test rubber-type compounds. The readings range from 30 to 95 points. A car tyre typically has a value of 70.
