The problem is that a lot of people, mainly amateur boat builders, are seduced by some of the claims that Titebond makes, and it finds its way into boats. Unfortunately, they don't specifically say that it's unsuitable for marine use, and leave that for users to decide for themselves.<br /> <br />Titebond 3 is not an epoxy resin. It is a water based aliphatic PVA resin. Although highly water resistant for outdoor applications, it is not suitable for marine use. <br /><br />It is not gap filling like epoxy, and cannot be used for filleting, waterproofing or taping joints. It also tends to creep over time, which makes joints underneath paint unsightly and therefore it is also unsuitable for laminating. Other glues and marine finishes will not adhere to PVA's.<br /><br />However, it's a very good and convenient glue for general outdoor use where joints are well made and tight fitting. I guess that rules out a lot of us amateur boat builders :)oztaylshttps://www.blogger.com/profile/01960808467729487401noreply@blogger.comtag:blogger.com,1999:blog-266108914902271629.post-84570292373743860302010-10-03T18:29:25.597-07:002010-10-03T18:29:25.597-07:00Can anyone enlighten me as to where Tightbond 3 fi...Can anyone enlighten me as to where Tightbond 3 fits into this tale?Nikolayhttps://www.blogger.com/profile/12217887261592067167noreply@blogger.comtag:blogger.com,1999:blog-266108914902271629.post-91371879198496717072010-10-02T04:32:19.141-07:002010-10-02T04:32:19.141-07:00"Most epoxies are not waterproof." Yes, ..."Most epoxies are not waterproof." Yes, you are absolutely correct! I'll just add the reason why this is so, if I may?<br /><br />A number of older technology epoxies contain solvents, and the evaporation of these solvents through the epoxy leaves microscopic tubes through which water (and air) molecules can flow. Just about any glue or paint that cures by the evaporation of a solvent won't be waterproof. This is also why steel will rust underneath paint.<br /><br />There are now more modern epoxy glues and epoxy paints that are "high solids". They exclude air and moisture very well, and are waterproof, and they are the beez kneez when it comes to glues, sealing boats and stopping rust in its tracks. There are even "one part" epoxy paints now that provide a complete seal against moisture and air. <br /><br />Yes, not all epoxies are equal, but the good ones rock when it comes to boats.<br /><br />However, most epoxies don't have much resistance to UV, so they need a UV resistant coating to protect them.<br /><br />As you may deduce, I'm an epoxy convert and when it comes to gluing or sealing boats, nothing else comes close in performance or will last as long. Viagra for boats it is.oztaylshttps://www.blogger.com/profile/01960808467729487401noreply@blogger.com
