Jonzjob Posted December 17, 2009 Share Posted December 17, 2009 I have just discovered a method of bringing some Z Poxy epoxy glue back to life. The resin had gone rock hard but the catalist was still OK. I have 2 lots of 4 fl ozs, 5 min and 30 min. I was at the point of chucking them out and I decided to phone Cherbourg Models in the U.K., where I thought I'd bought it from, to see if I could get some more resin. The guy there said they didn't sell it but most of the epoxies are similar in that when they get very cold an enzime seperates out of the mix and crystalises sending the lot solid. You can sometimes re-incorporate the mix by putting the bottle in boiling water and heat it through and then give the resulting liquid a bloody good shake. Well the outcome is that I not have 2 lots of resin that is back in liquid form again and should be as good as new! Link to comment Share on other sites More sharing options...
Théière Posted December 17, 2009 Share Posted December 17, 2009 And another tip, be more careful and you wouldn't have needed the glue [;-)] Link to comment Share on other sites More sharing options...
NickP Posted December 17, 2009 Share Posted December 17, 2009 That sounds good Jon, but do you or anybody else know if or where you can buy hardener for "plastic padding" type products? The marketing for those products was ever so clever, they told you how much hardener to use and you always ran out of hardener first, therefore having to buy a new complete kit as they never sold the hardener separately.

Jonzjob Posted December 17, 2009 Author Share Posted December 17, 2009 Well TP, I wonder why you needed a big tube? Break sumfin big did we [:P][6]As far as my repairs are concerned if you ever meet someone who has never broken a radio controlled model aircraft it is because they have never flown one!! Radio control = always radio, sometimes controlled! Plastic pading is the other popular stuff. Polyester resin based and nowhere near as strong as epoxy, smells more too. Then again if you are using a lot of epoxy it is a good idea to do so in very good ventilation because in large doses it can be carsenigenic. Not as expensive either..This was my last polyester resin project. 5 foot radius, 10 sq M of chopped strand mat, 4 gallons of resin and lots of glass splinters![IMG]http://i47.photobucket.com/albums/f180/Jonzjob/Johns/Fglasssteps2.jpg[/IMG][IMG]http://i47.photobucket.com/albums/f180/Jonzjob/Johns/Fglasssteps3.jpg[/IMG]Edit :- I forgot to add that it took just under 1 litre of methyl ethly keytone peroxide too. That's the same stuff as you had for the Plas Padding btu in liquid form. So at least I know I ain't going to run out of catylist (hardner) [8-|] Link to comment Share on other sites More sharing options...
Théière Posted December 18, 2009 Share Posted December 18, 2009 Morning Jonzjob,Fortunately I am paid to fix other peoples breakages [:)]So a big tube is always handy, BTW the tube I bought 16g was only £1.75 not the rip off price that guy had on ebay.That is a brilliant job you did with the escalliers.Radio control planes, my mate moving to Spain, van loaded to the roof, couldn't fit the o'l plane in.I said, whilst we have a minute lets go and fly it, as you always crash it it will be easier to fit in afterwards [:D] Link to comment Share on other sites More sharing options...
Jonzjob Posted December 18, 2009 Author Share Posted December 18, 2009 Morning TP, I'm glad you didn't say 'good morning' 'cause it's snowing like hell here and as it's -1C it's sticking too! If it carries on we ain't going to get to our AVF French class in Carcassonne this afternoon..Ta about the escalliers. If I ever got the chance to make some more I would go AWOL. Start to finish they took about 10 weeks and then they had to sit for a month before going into the pool to disperse the styrene gas from the resin. They have a 2 inch pool type plactic piping frame and when they first went in the pool the bloody things floated![:-))]. My mate was in the pool helping and he wouldn't take my mains drill to put some holes in the frame to get the air out! Chicken or wot? I had to do it with my battery drill.Radio control. Many a true word is spoken. One of the first things I learned was when you repair a polyester fuselarge DON'T do it with epoxy resin. They don't like each other and refuse to bond together... Your mate didn't have much forthought did he? My priority would have been to get the models in first! I made sure that mine did when we moved over! Did his model fit afterwards?

Théière Posted December 18, 2009 Share Posted December 18, 2009 Years ago at, I think it was the model engineering exhibition, a guy sprayed a mains drill with WD40 and the used it in a tank of water [:-))]Mate had plenty of forthought.............you haven't met the wife [:D] Link to comment Share on other sites More sharing options...

Dog Posted December 20, 2009 Share Posted December 20, 2009 What is this fascination with glue do you sniff the stuff?I am an expert on double-sided tape dispensers. Don't use anything but Pritt dispensers the other brands are all absolutely useless in comparison. Link to comment Share on other sites More sharing options...
Jonzjob Posted December 20, 2009 Author Share Posted December 20, 2009 Prit is good stuff for paper and the like, BUT when you get to the butch stuff like wood and plastic and metal and fings then you need somfin more butch. With wood then you're into PVA and sniffin that is a real art and only for those with a sensitive nose. No bloody good for me though, I just use it to stick bits-a-wood together. Then you get onto the specialised stuff like 'no nails', but I will let the ex-sperts tell you about those gluez! Link to comment Share on other sites More sharing options...
Dog Posted December 20, 2009 Share Posted December 20, 2009 I got through hundreds of gallons of PVA before I retired. Nothing like it for scrap pads and accountants pads. I even invented multicoloured PVA gluing. Link to comment Share on other sites More sharing options...
