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

Product Information

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

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. Water - visibly dripping through into your cabin during rainy days. Leaking water can often be seen forming small droplets on the bottom of protruding bolt heads. Wait for a forecast of rain or cheat and use a hose to find leaks. If you get your bilge bone dry beforehand, you'll be able to follow the trails of water from any leaky hardware by looking at your bilge areas with a hand torch. This method works amazingly well. If you have a dirty bilge it seems to be even easier and the trail seems to show up clearer where the dirt is wet. 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. 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).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. We've even created a beautiful acronym for you to remember: 'SFCSS' (pronounced; Suu-Fuu-Cissss). See, if that's not catchy enough for you then I don't know what is! Terms Explained 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.

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. Everbuild Stix-All is a one component adhesive sealant utilising the best elements of silicone and polyurethane technologies to create a hybrid. It hasn't been designed for marine use specifically but It is compatible for adhering with most the common materials and can be applied on both damp and wet surfaces. It will bond to metals, plastics, glass, concrete, plasterboard, plaster, polyester, perspex, glass, wood, enamel, painted surfaces and GRP. 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. Specifically designed as an easy flow flooring grade for all concrete saw cuts and floor slab expansion joints where abrasion resistance is requiredMy memory of the MSDS data is that OB1 was essentially the same as CT1 apart from an additional component. I can't remember what it was but did write that I thought it likely to enhance cross-linking to either speed up setting time or strength of the material, probably both (by promoting formation of urethane links). 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.
