Sikaflex Marine Handbook

High-tech, High bond.When the marine industry specifies a product, durability is highon its list of requirements. And for the boat owner, durability isan essential prerequisite for the smooth running of the vessel,the untroubled enjoyment of passengers and the sheer joy ofsailing. Whether at the wheel of a power boat or at the tiller ofa sailing yacht: there’s nothing quite like that feeling of freedomwhen you’re out there on your own, facing the elements ... orthat feeling of total tranquillity with only the horizon ahead andblue skies above. Times like this make your boat a possessionto cherish, and a valuable asset that you’ll want to protectagainst the elements for many years to come.Water leaks, in particular, can damage your prized possession,leaving unsightly marks along the hull and causing woodworkto rot and metal components to corrode. To avoid expensiverepair bills, watertight seals are absolutely essential.Deck caulkingFor timber decks that are completely watertight and weatherresistant, Sika has developed Sikaflex ® -290 DC. Extremely easyto use, this one-part polyurethane deck caulking compoundcan be sanded flush with the deck when cured to give abeautifully neat, clean finish.Different productsSame benefits.Sika pioneered the development of one-componentpolyurethanes for marine use. Our global technical resourceshave enabled us to produce a wide range of products, eachaimed at a specific marine application. Although the individualproduct characteristics vary, they all share the following features:– One component – no mixing necessary– Excellent gap–filling capabilities– Permanently elastic– Can be sanded and overpainted– Excellent non-sag properties– High solids content, low V.O.C.– Non-corrosive– For use above or below the waterline– All are specifically designed for marine use.SealingResistant to weathering, seawater and ultra-violet radiation,Sikaflex ® -291 is the perfect all-rounder: an all-purpose flexiblemarine sealant that bonds extremely well to all the standardmaterials used in boat construction. Its outstanding elasticityensures a durable, long-lasting seal.BondingJoints that are subject to extreme dynamic stresses require ahigh-strength elastic adhesive with good gap-filling capabilities.Sikaflex ® -292, with its excellent shock-absorbing andvibration-damping properties, has been specially developed tomeet these requirements in the punishing marine environment.When your safety may depend on it, only the best is goodenough.Bonding of plastic glazing panelsThis is an application that calls for a UV-resistant adhesive witha high degree of elasticity. Sikaflex ® -295 UV combines thenecessary elasticity with exactly the right consistency tomaintain the required bond line thickness, thus ensuring thatthermal movements in plastic glazing panels are absorbedprogressively, without undue build-up of stresses.Bonding and sealing of mineral glassDirect glazing of mineral glass requires a purpose designedadhesive with the right combination of application propertiesand performance characteristics. Sikaflex ® -296 is a fast curinghigh performance elastic polyurethane that is suitable for alltypes of mineral glass. It’s high UV resistance also makes itsuitable for backfilling and sealing operations.Bedding and bonding of panels and sheet materials.Sikaflex ® -298 is a viscous, full-bodied adhesive that has beenspecially formulated for the waterproof, flexible bonding oftimber strip decking, deck planking, plastic deck coverings andprefabricated timber deck panels. It is easy to work with, andgives professional results every time. The permanently elasticadhesive layer has a cushioning effect absorbing shocks andminimizing the transmission of impact sound.
