Good glue for plastic

[Mr Johnty]

Hi .

Can anyone recommend a good glue for plastic. 

I have tried super glue and epoxy both work for a while then when the joint flexes it just comes apart again. 

It's for the front bumper on a 1/10 land rover defender  I need somthing that will melt both sides of the plastic and bond them together .

Like the old airfix models used to .

Would it be as simple as aitfix glue 🤔 can you still get it 🤔 

Cheers boys and girls.

REALLY depends on what the actual plastic is.

 

Airfix glue ( and all the similar variations...I use Tamiya extra thin... ) work on polystyrene type plastics, but only that.

 

If it's a nylon type plastic. .... you could try this:

does work, and just needs a soldering iron and cable tie for a filler rod. But again...depends on your plastic type.

Thanks for that just watched the video very interesting 👍 

I will try the plastic cement first then go from there.

Thanks again.

Adding to this what’s the glue to use for light lenses and windows ? as I need some for the super scale build I’m getting ready to do

Plastic is a funny one, it’s down to what type of plastic as to what is best/effective. 
As a run down of adhesives/glues I’ve used on various plastics,

E6000/Shoo Goo would work for windows, it’s useful for all sorts of stuff, a general glue I guess. I personally use T8000/B7000(it’s a phone repair shop blend) because I get it cheap through work. 

Superglue would be good too though that risks whitening of the clear plastic and can be brittle sometimes.
Araldite/Epoxy could work too, not sure if folk use it for windows.
ABS pipe cement/Solvent cement is a good one for various stuff but it’s very brutal on fumes, will stick a lot of plastics together(and some other things).
Plastiweld is another good one for ABS type plastics. Not for much use on others I don’t think. It’s basically butanone so again, fumes. 
Im sure there’s more out there but they won’t come to mind

I’m worried about the fogging up if I use the wrong stuff I keep seeing ca glue don’t know what the difference is between glues if I’m honest I gust use the strongest glue I can get when I need it for around the house 🤣

Thin layer of clear silicone? 🤔

I would think it would be a bit tricky or can you get small amounts of clear silicone? only know the big tubes of it 🤣

You can buy small plastic syringes, it should be possible to put some silicone into one and then be able to apply a tiny amount.

[wombat]

That's what I've done in the past, filled a syringe from a big tube then applied it, worked well

[ad456m]

Silicone is a good shout, aquarium silicone is available in wee tubes, 50 grams or thereabouts 

[RC4WD fan]

I’ll have a look have an aquarium shop near me I’ll see if they have any if not at lest I’ll get to look at some nice fish 😆

Make sure the surfaces are extra clean and it’ll stick all the better. I held my Blackfoot body back window in for about 6years with silicone, it did loosen slowly so I didn’t lose it when it came out. It did get a good amount of punishment in that time

I’ll be using it on a scale trail truck build I’m doing over the winter so nothing other than a bit of mud if it keeps the lenses and windows on and won’t fog up then I’ll be happy 👍

I use this, a static modelling forum recommended it.

I use Humbrol Clearfix, but that Glue & Glaze looks like it’s probably the same stuff but cheaper.

I’m sure I’ve seen that at my local hobby shop I’ll pop in tomorrow and have a look 👍

For sturdy joints, I've had good results with plastic cement, similar to what AI totally get your struggle with plastic bonding. I've been down that road with RC cars, too. For sturdy joints, I've had good results with plastic cement, similar to what Airfix used. You might find it labeled as "model cement" at hobby stores. It creates a chemical bond by slightly melting the plastic, making a strong connection. I'd recommend giving it a shot. Also, you could use epdm lijm drukvat. Good luck!irfix used.
