Duralac Equivalent

[Boathook]

There was a thread quite a while back about a more 'modern' version of duralac in that it stayed 'soft'. I have just had to pay an engineering workshop some money to get 3 s/s screws out of an aluminium fitting due to hardened duralac and corrosion.

I had tried various methods (freeze spray, penetration fluid, heat) of getting the screws out, but nothing worked hence the workshop and they did a good job by the way.

Tef-Gel is another product.

There's a new version of Duracell Duralac claimed to be better than the yellow:

I love it when spellcheckers get in the way

Thanks Poignard.

Duralac is in fact a paste of barium chromate so posable to make yourself but it is very toxic

I was sold for thing similar to Duralac but did not set so easy to clean off after use.

I got a 500ml tin direct from the manufacturer in Birmingham last time I wa in the UK but one guy I had working for me left the tin open and it all set hard

Barium chromate

How does Duralac work?

 

[doug748]

The green was developed to avoid the use of chromate in the yellow stuff. Generally, these replacement products are not always outstanding, tho I have not used these myself, so I don't know. The specs say it does set over time, in the same way the old formulation does.

Rigging shops are shockers for not using the paste properly, in particular all fixings should be dipped before insertion and you need good coverage on mating parts.

tefgel is so much easier to use. A lot less messy. A little seems to go a long way. I helped disassembled some parts on a mast that had been fitted years ago with Tefgel. Everything came apart super easy. I was impressed.

Yes, and it seems to be preferred by many riggers these days. Duralac is filthy stuff to use.

Another one is Lanocote. Windpilot use it assembling their windvanes so presumably they think it's long lasting. A good option if you're fond of the smell of sheep.

Yes I'm a lanolin fan, top stuff, pure lanolin (with sheepy bits removed) is much cheaper but does the job. I smeared a thick layer over my Aries and it lasted a couple of years, it laughs at salt water.
I found an old Lanocote bottle in the engine room, it has a very strong farmyard aroma!

Tef-Gel is another product.

I looked it up earlier seems a bit pricey

Yep here another adept of Lanocote (and Windpilot )
I also used "Mastinox", I think it's very similar to Duralac, what a mess it sticks everywhere. OTOH, probably a very good investment I paid maybe 10-20 euro at that time, just checked the prices now

I bought a tube of Duralac in 1997 when I bought my boat and I have hardly used any of it.

The manufacturers don't make their profits from what is actually used but from what dries out in the tube!

 

[vic008]

Poignard, so totally agree! It dries out and have to throw it away. Shocking waste!

They do a smaller one in a syringe for about a tenner. Super easy to apply with no waste. It goes along way

Thanks pvb.
I do have a tub of tef-gel and was keeping it for the rigging screws but I might just as well use it else where rather than look at an unused product.
Lonocote is something I will try to obtain, but most seems to be from USA.

Amazon UK also offer a 10ml tube for less than a tenner.

I use Anhydrous lanolin (wool fat) to prevent stainless steel galling

Lancote is basically sheep fat ( wool fat)

Lanocote is derived from sheep lanoline, one of the worlds oldest greases, while polytetrafluoroethylene (PTFE, aka Teflon) is a 20th century synthetic

I get a 500ml tub from my local pharmacist (Dispensing Chemist)

Lanolin Anhydrous 100% Pure

I filled a few small syringes from my big tube, sealed them in bags and worked very well and cheap
