Title: Styrene to styrene
Post by: rickles23 on March 22, 2017, 02:34:17 pm

Hi,


Just got the parts to make my own Motorflotte.

I believe the plastic used is  styrene.

I tried gluing two scrap bits with Superglue but after 24 hours I was able to snap the two pieces apart.

Have you a recommend for a better glue?

Regards

Use liguid polystyrene cement, I use a brand called EMA, search ebay  and ye shall find!!

Place the two part together and apply with a small brush, capilliary action does the rest by melting the surfaces of both parts and fusing them into one piece.

Straight MEK (Methyl Ethyl Ketone).  Buy it at a hardware store in the paint department.  Comes in quarts in the US for about $8.  A lifetime supply for a model builder.  Tape the parts together in perfect alignment, then run a narrow bead of MEK down the seam with a small brush.  It bonds in seconds, and stays strong for years.

Oh, and use plenty of ventilation.  MEK is hard on the lungs.   :o

If you go to EMA web site they sell a pipet, it's a glass tube with a syringe needle on the end. Fill the tub with for mentioned liquid then just run the needle along the joint . It is very controllable . One of my best buys .

I am not aware that paint departments sell it in the UK. What, in connection with paint departments, is it used for?

MEK is a solvent for some kinds of paint.  I'm not sure which ones-I never used it for that.

Well Fanatic, you made me curious.  Here's a link that explains MEK/Butadone more.  Note the heading "Application."   :-)

In the oil refinery where I was an engineer MEK was used to dewax lubricating oil, in its manufacturing process.

Thanks for the information but I think that you forgot the link. I have read the Wikipedia article & I am surprised that hardware store paint departments sell it.  I think that you have much more adventurous paint departments than we do.

Plastic weld and an identical product made by Deluxe materials is available from many model shops and Squires sell it as well as MEKPAK (They used to) which was M.E.K but is now more like Dichloromethane that Plastic weld is made from.
