I am seeking confirmation that "Duct Seal" sometimes known as "Duct Seal Putty" is the same material as butyl tape but has the advantage of being more readily available for purchase and economical. Some of you may be familiar with duct seal as it often used to seal around electrical service entrance cables where they enter the meter housing.

I've used both butyl tape and duct seal in the past and they seem identical. The MSDS for duct seal lists the chemical family as "butyl rubber composite" which sounds promising?
Just like with polyurethane sealants there are many differing grades and compositions and some are more suitable than others to marine applications. Duct Seal is not the same as Bed-It Tape. Could it work? Sure, but having tested over 40+ products sold as "butyl tape" I can assure you the variances are far and wide. Some of these tapes are sold for less than 1/3 what I pay direct from the manufacturer.. "Fillers", recycled content", "solvents" and all sorts of other things can be added to the product to make it less costly, but they don't make it better...

I know this is an old post, but is there a specific brand that you find better than others?

I believe he included a link to a product at the end of the post. I would copy/paste it but am still new here and not sure of all link policies. but have a look

Re: Bedding Deck Hardware With Butyl Tape

We have an old fashioned hardware store in Victoria. No label - just in a roll with wax paper on one side.

The best place to buy guaranteed good butyl is here:Need Butyl Tape ?? Photo Gallery by Compass Marine at pbase.com

Re: Bedding Deck Hardware With Butyl Tape

I will be bedding the wooden grab rails with Butyl from Maine Sail and this will be coated with Cetol.

My question is: Could Cetol harm the butyl? I am sure I will be recoating the wooden pieces many times over the years, and during recoat, some of the Cetol could go in the Butyl. I am wondering if whatever is in the product could slowly cause the Butyl to decay.

Thanks

Re: Bedding Deck Hardware With Butyl Tape

I have one question, I'm esealing around my chain plates. I want to pour thinkened epoxy around the chain plate to seal the balsa and ensure no water get in. I also want to leave a uniform gap between the hardened epoxy and the chain plate so that I can seal it. Could I install the chain plate wrap the chain plate with butyl tape then pour the thickened epoxy around the butyl tape so that once it hardens the butyl tape will be sealed against the chainplate?

I'll let someone else answer, but you might want to change your name so you don't get spammed.

Re: Bedding Deck Hardware With Butyl Tape

Like others came across this post when looking for answers on how to deal with my leaky chain plates. While removing the chainplates was a bear as the manufacturer had used 5200, following the demo made me feel confident that it will be a once and done repair.

I generally prefer to wrap with packaging tape or electrical tape. The heat of the epoxy cure may soften the butyl. Electrical tale works well.... Butyl works in compression so even after the pour you'd need to re-bed. If potting the core put a slight chamfer in the deck hole around the chain plate.
