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. 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. Substrate: The surface material upon which the adhesive/sealant is applied to form a bond or joint. Dæksemner, såsom ventilatorer og dæklister, skal være vandtætte, men udsættes ikke for store træk- eller vridridninger. Cohesive failure: The adhesive/sealant fails before the adhesive releases from the substrate – this usually gives a higher strength value than through adhesive failure.

A good bond: this will vary, depending upon whether the application is permanent or will require dismantling Liimasauman riittävän kerrosvahvuuden varmistamiseksi suosittelemme sauman levittämistä poikkileikkaukseltaan kolmiomaisena (kts. piirros alla). Verklebung und / oder Abdichtung von Teilen, die hohen mechanischen Beanspruchungen ausgesetzt sindVerklebung und / oder Abdichtung von Teilen, die geringen mechanischen Beanspruchungen ausgesetzt sind 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. Tensile stress: The force is perpendicular to the cross-sectional area under load. Products on test:

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 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.

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: 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. Tjek forbehandlingsoversigten for behandling af underlag før limning, og følg processen i henhold til applikationsguiden.
