Transportation and storage of liquefied gases require very efficient insulation. Sika supplies structural adhesive and sealant systems for this specific application. In addition, similar demands for acoustic flooring and other standard applications need to be met on both, tankers and oil rigs. Sika as a competent partner to this industry offers a full range of products to meet these requirements.
Resistant to weathering and seawater, Sikaflex-291i is the perfect all-rounder: an all-purpose flexible marine sealant that bonds extremely well to all standard materials used in boat construction. Its outstanding elasticity ensures a durable, long-lasting seal alike all other Sikaflex Marine sealants and adhesives. Sikaflex-291i features 1-component, easy to apply, high elastomeric characteristics.
Joints that are subject to extreme dynamic stresses require a long-lasting high strength elastic adhesive with good gap-filling capabilities. Sikaflex-292i, with its excellent shock-absorbing and vibration-damping properties, has been specially developed to meet these requirements in the punishing marine environment. When your safety may depend on it, only the best is good enough.
Sikaflex-296 has been formulated for use on all types of mineral glass windows. The high-performance, yet elastic Sikaflex-296 adhesive is especially designed for bridging tolerances enhancing high modular performance. UV resistance renders the product suitable as a back-filler simultaneously.
Sikaflex-298 is a low-viscous, yet thixotropic full-bodied adhesive that has been specially formulated for the waterproof, flexible bonding of timber strip decking, deck planking, plastic deck coverings and prefabricated timber deck panels. The product is very easy to work with, and supplies professional results every time. The permanently elastic adhesive layer has a cushioning effect, absorbs shocks and minimises the transmission of impact sound.
Fire is one of the most dreaded situations that can be encountered at sea. With no feasible means of escape, there is little option but to combat the blaze. Therefore, all apertures used for power distribution must be fire protected. The same precautions apply to electrical conduits, tube systems, air conditioning channels and service shafts. The Sika Cable-Duct Fire protection System has been specially developed for this purpose. This quick, simple and efficient system meets all international fire protection safety standards.
On board ships, there are several dominant sound and vibration sources like diesel engines, gearboxes and propellers that transmit these kinds of energy. As a consequence, floors are not only expected to be smooth and level, but to play a major part in noise and vibration suppression. Sika offers a range of products each of which have a floor levelling and smoothing aspect as well as varying degrees of noise and vibration reduction properties in order to meet the requirements from both ship owners and regulatory bodies.
LPG tankers have tanks that pose a unique challenge for naval engineers and architects. The liquefied gas is carried at a temperature of -62°C, requiring that the tanks are well insulated. This insulation is contained between two skins of steel, one forming the inner liquid gas storage vessel and an outer one that provides protection for both the inner tank and the insulation.
The insulation is provided by foamed polystyrene slabs that are bonding with two component polyurethane adhesives called SikaForce ensuring fast working processes and high durability.
