Sticky stuff, (sort of)

[Bryn Jarvis]

Hello all,

This is one for the Engine Room fraternity. On one of my ships I remember using a compound to repair a cooling water inlet. From memory, you had to stir a tin app 250gr of thickish grey paste, then add the activator & keep stirring vigorously, but, there's always a "but" as soon as the tin started to get warm, you had to apply it to the repair area PDQ, if you didn't, it literally set rock solid in the tin. I remember using it just once, but it took two wasted attempts before I could get it on the repair area. The 2nd wasn't too pleased. I'd love to be reminded, as to what it was called. Great days.

Take care all,

BeeJay. (Bryn Jarvis)

May have been Thistlebond , Corybond, thickish grey paste may have been Devcon but that did not really cure that fast.

Bang on James, brilliant, it certainly was Thistlebond. I can see myself in the engine room mixing it & before getting it right, ended up like a lolly on a stick!

The vast majority of these materials were epoxy resins; if the pot had started to warm up then you would be lucky to acctually get a successful application, especially if you were impregnating glass. Epoxies are usually affected by ambient temp. so the warmer the environment the faster it will go. Thistlebond had a relatively short pot life even at lower temps. if I recall.

Before I would use Thistlebond in the Tropics /Gulf I would have put it in the Fridges. Then on ocassion paint with resin A the area for repair and the tape with resin B. The tape being porous you would still get the resin reaction, mix the rest of A&B together and paint over the tape, again a quick wrap with more tape.

Must have been like the quick fix glue we have today, many a time I have had my fingers stuck together and the part with none on it. sets like lightening.

Thanks for the follow up posts. The sticky stuff I use today is called SX Siroflex Trade Strength Superglue, 50gm, bought online. I've used it for sticking a plethora of different materials. Hope I haven't broke any rules by naming a product?

Eh! Bryn lad, where would we be without trade names for jokes and comparisons, although many slogans would be considered inappropriate today we are old enough to ignore the PC brigade, one particular slogan .....'I wonder where the yellow went when I brush my teeth with Pepsodent' may not be very popular in China

you have been very lucky James as to achieve a proper cure you need to mix the resin and catalyst in pretty accurate proportions, deviations could result in failure to cure; I have spent the last 31 years of my working life in occupations in the resins based materials industry, predominantly polyesters and vinyl esters which utilise a 50:1 ratio predominately, as well as some epoxies which are usually 1:1, 2:1 OR 3:1 mix ratios depending on the type. Like other things there is a plethora of variations of these materials which have been refined to serve different purposes. My main focus for last 20 years has been on UV cured polyesters and vinyl esters, for industrial applications.

Not lucky Tony just knew what I was doing, the tape is Porous, never had a failure. You could always tell the quality of ships an engineer sailed by his ability to use Thistle bond or similar resins. Preferred Cory Bond as it gave a slightly longer time to work on a pipe repairs.
