Everbuild Tecnic Puraflex 40 High Modulus PU Sealant and Adhesive, White, 300 ml

Product Information

Compatibility - will it work with your material you wish to bond it too? Will it be safe for below the waterline? Not resistant to organic acids, alcohol, concentrated mineral acids and caustic solutions or solvents. 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

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. UniBond FlexTec FT101 is a one component hybrid polymer which can be used to seal, fill and bond. It claims to be able to bond without the use of a primer to a wide range of materials but doesn't specify which ones it does not. It can also be applied on both damp and wet surfaces but does take 24hours to set and may not ideal for fast same day repairs. You need good mechanical adehsion with flex. Look at the datasheet for Sikaflex 291i. You don’t want to use the 3M products as the hose at some point will need replacing. 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. 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.Elongation Break - Is the % of stretching that the product breaks at. Some sealants have been designed to stretch more than others. There were posts about the "similarity" with CT1 and that it was actually an improved formulation. Also a threat of legal action plus mention in advertising that the OB1 formulation had been in use for over 15 years and made by a private company. I could not find details of the manufacturer and it almost seemed to be a big secret. It appeared reasonable to assume that some sort of legally binding agreement had been signed regarding direct competition or comparison with CT1 by name (could be wrong).

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. aluminium, polyester, glass, uPVC, stone, ceramics and more. Use Puraflex 40 in sealing and bonding applications subjectis 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. Sealants were originally designed to patch holes in planes during the war but since then they've got a lot more complicated. Corporate competition means companies are continuously trying to outdo each other. The marine industry is constantly screaming out for products that last longer and perform better and subsequently, we are fed increasingly better sealants. A lot of companies who create sealants eventually wise up to the fact that their product will work in the 'marine' industry, and often subtly add it to their datasheet without it being a specific marine product and liable for leisure tax. 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! Specifically designed as an easy flow flooring grade for all concrete saw cuts and floor slab expansion joints where abrasion resistance is required
