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

Product Information

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

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.Primer is not always essential unless using on porous surfaces like concrete. If primer is needed, use Sika 3N Primer LIMITATIONS

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. 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.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. 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.

aluminium, polyester, glass, uPVC, stone, ceramics and more. Use Puraflex 40 in sealing and bonding applications subjectGreg - I have a Meridian 391 2010 the front windows are leaking a little bit and is dripping in the master state room on the bed. I have tried to fill the area where the window sits on the lower side with silicon to achieve a water seal. Does not work. Pulled out all the silicon and I am going to try to fill and seal with Butyl or polyurethane. which would you recommend?

Paint types vary so conduct a trial prior to full application. Some paints have low movement and can I’m trying to visualise what it is you’re trying to achieve, I agree that a few photos could definitely help, send them over to [email protected]. If it was me i’d probably get a coded welder patch the hole and have a designated skin fitting with shutoff valve for the inlet.

Alternative Products

Polyurethane sealants create an extremely strong mechanical bond when used on the correct surface. They are UV resistant and can be used below the waterline. In the aviation industry on unpressurized aircrafts, windows are sometimes attached using adhesive sealant only. This is a testament to the strength of modern sealants. It's notable that polyurethane is not compatible with acrylic perspex and other types plastic glazing.
