A non-adhesive sealant will generally rely on the aid of a fitting, screw or bolt to create a waterproof seal. With a normal sealant, you are essentially creating a waterproof gasket. You can't rely on normal sealant to hold anything in place; you are relying on a method of fastening, for example; a screw or bolt. Types Of Sealant Specifically designed as an easy flow flooring grade for all concrete saw cuts and floor slab expansion joints where abrasion resistance is required Here is the link to the datasheet for Aquaseal – http://www.everbuild.co.uk/image/data/Tech%20Sealants/mSEAL%20595%20Tech%20Datasheet%20Rev.%202.pdf It is said that silicone is an inert synthetic polymer compound and is technically part of the rubber family. You can imagine why its been a favourite in boat maintenance for some time. Its UV resistant, heat resistant, a great insulator and is ideal for creating gaskets. Its downfall is that it makes for a weak adhesive and for this reason sometimes is unpractical for use below the water line. Resistant to fresh water, seawater, limewater, sewage effluent, diluted acids and caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils.

So to summarise, imagine you're an evil man wanting to pull someones' arms off using horses. Tensile strength is the amount of horse's you would need to pull them off which is measured in N/mm2 or MPa. The elongation break is how long the poor persons' arms will stretch before they rip off - ouch! My first thought , what’s caused the corrosion in the first place, do the anodes need replacing and are there earthing issues with the leg. I’m trying to visualise the issue, the swaging makes it a little more difficult. I’m not entirely, sure how any tube simply put through and hole will have a good seal. For a gasket to work you really need tension pushing outwards from the ID to seal. rubber changes over time, due to the elements and exposure. is all around one part polyurethane adhesive sealant that can be used to bond wood, gel coat and fibreglass. It can also be used above and below the waterline.All surfaces must be dry and dust free before using Everbuild Puraflex 40. All flaking or loose surface coatings and any old sealants should be removed before application. In addition to that, when using on glass, metal and aluminium, areas should be cleaned with a proprietary solvent cleaner before application for optimum adhesion. When using Everbuild Puraflex 40 with solvents, always ensure adequate ventilation. Avoid heat, sparks and open flames. Observe and follow all precautions listed on the solvent container label. It is not recommended for application to surfaces that are below 5˚C as it is impossible to guarantee a dry, frost-free surface at these temperatures. Therefore the sealant will most likely fail. It is unlikely that priming will be required; however, concrete must be sealed using a Primer. After that, if you are in doubt, consult Technical Services. PRIMER Compatibility - will it work with your material you wish to bond it too? Will it be safe for below the waterline? It looked great for a few weeks but then the planks dried and swelled etc and it popped the sealant. The sealant wasn't to blame here, the problem was there was a great deal of water getting in through the topsides of the boat. Delamination, leaky fittings and windows resulted in water pouring on the inside of the hull like a waterfall. As the boat was out of the water the planks were dry on the outside and taking a hammering of UV but wet on the inside. The new owner renewed the caulking, dropped it in the water and the problem seems to have been solved. I have since borrowed and cruised it and noticed no water ingress now that planks have swollen. Hi Rich, If you are using aluminium frames then essentially the sealant will only need to be used to create a gasket. There is my opinion is no need to have a good adhesion if the window is held tight by rivets or bolts and a frame. Aquaseal mSEAL has been known to work well for this purpose and Geocel Marine Rubber Silicone is something I have personally used with good results.

Tensile Strength - the resistance of a material to breaking under tension. To put it even clearer this is the amount of force a material can take until it breaks apart. This is measured in N/mm2 to MPa and can normally be found on a product datasheet. Elongation Break - Is the % of stretching that the product breaks at. Some sealants have been designed to stretch more than others. Remove all of the sealant taking care not to damage the glass or frames, using a sharp knife. Tape the window and frames up using frog tape or blue painters tape then apply the sealant in even smooth beads. A favourite amongst boating enthusiasts CT1 is suitable as a universal adhesive and will work in all applications. CT1 has no shrinkage and can be applied in both damp and wet conditions. It adheres to most metals (including lead) as well as glass, mirrors, wood, polystyrene and GRP. This product is recommended for sealing and bonding metal panels and trim. Expansion joint sealing in conrete panels, floor joint, road and bridge construction. Sealing in applications subject to vibration and mechanical abrasion. Marine applications provides resistance to salt water multitude of sealing and bonding applications in the automotive and engineering markets. Bonding in container fabrication.aluminium, polyester, glass, uPVC, stone, ceramics and more. Use Puraflex 40 in sealing and bonding applications subject Not resistant to organic acids, alcohol, concentrated mineral acids and caustic solutions or solvents.
