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. 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.

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: Cohesive failure: The adhesive/sealant fails before the adhesive releases from the substrate – this usually gives a higher strength value than through adhesive failure.Verklebung 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.

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 Liimasauman riittävän kerrosvahvuuden varmistamiseksi suosittelemme sauman levittämistä poikkileikkaukseltaan kolmiomaisena (kts. piirros alla).

A good bond: this will vary, depending upon whether the application is permanent or will require dismantling Verklebung und / oder Abdichtung von Teilen, die hohen mechanischen Beanspruchungen ausgesetzt sind 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. 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. 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:
