RMweb Premium Andy Hayter Posted January 13, 2020 RMweb Premium Share Posted January 13, 2020 I don't think so Dave. Rubbing alcohol is as the name implies an alcohol, although I believe you can get various types so it may be based on ethyl (drinking) alcohol, or iso-propyl alcohol. MEK is a ketone not an alcohol and methylene dichloride is also something totally different. Link to post Share on other sites More sharing options...
RMweb Premium Dave Hunt Posted January 13, 2020 RMweb Premium Share Posted January 13, 2020 (edited) No, rubbing alcohol is isopropyl alcohol surely, not methylene chloride? I use IPA for track cleaning and methylene chloride for sticking plastic. Edited January 13, 2020 by Dave Hunt Hit send too soon 2 Link to post Share on other sites More sharing options...

dasatcopthorne Posted January 23, 2020 Share Posted January 23, 2020 Sorry. Did I say Rubbing Alcohol is Butanone. Stupid me. I know better than that. Really. Dave Link to post Share on other sites More sharing options...

I find that I can apply the correct amount quite easily and there are very few fumes compared to using a brush. You can also pick up and put down the syringe quite easily with one hand - no "brush in bottle" action required with the possibility of spilling the bottle. The syringes and blunt needles can be got from Ebay - maybe get an assortment of needle sizes to let you decide on what size is best for you. Jim.

I got my syringes and needles a few years ago. The syringes were a pack of 10 x 10ml and the needles were an assorted pack of 25 IIRC. The suppliers don't appear on Ebay these days but there are a good few advertising syringes and/or needles. Here's one for a pack of five syringes and needles https://www.ebay.co.uk/itm/5-Packs-10ml-Syringe-With-5Pcs-14-ga-1-5-Blunt-Tip-Needle-5Pcs-Clear-Tip-Caps/263808616478?hash=item3d6c38081e:g:Ix0AAOSwoF5cdmPF ...and if you search on Ebay for syringes and needles you can find a lot more. The advert above is sourced in China so you would have to wait a week or two for delivery. You might find others with quicker delivery. Jim. Link to post Share on other sites More sharing options...

Hello, I was thinking about suitability with regard to the effects of the solvents on the plastic syringes. trustytrev. Link to post Share on other sites More sharing options...
RMweb Premium Andy Hayter Posted January 25, 2020 RMweb Premium Share Posted January 25, 2020 The syringes themselves are most often made from Polyethylene or polypropylene which are pretty inert to most solvents. The bigger concern might be the "rubber" O ring that many have on the plunger. Those with a diaphragm may be better protected. Thorough cleaning out and washing - eventually with water - should extend the life of such components. Most of these syringes are designed as single use, but of course as modellers with long pockets but short arms, we tend to reuse them over and over again.

flubrush Posted January 26, 2020 Share Posted January 26, 2020 the reason I bought a bulk pack of syringes was that I suspected that the solvents we use might affect them. But my experience has shown that Butanone (MEK) has little long-term effect on the syringes. I've just checked the three syringes I've used over the past year or so and they are still in working condition. I always empty them if I think they will be on the shelf for some time. I think that the only solvent I found that had some effect on the syringes was Plastic Weld but only after a period of use, so probably taken as acceptable considering the low cost of the syringes.
