solvent bonding with methylene chloride

[@lavague7648]

It was hard to find methylene chloride in Greece. This solvent is highly regulated in Europe. I am impressed that works so well on acrylic. I tested also acetone as other videos suggested but it does not work. Many congratulations for this educative video.

Excellent video - shows technique and informative about materials. Thank you!

[@deedeemac]

Fabulous information! Exactly what I needed. Thank you!!! 🇨🇦

[@joshuaritter791]

Very helpful video. Thanks!

[@chrissewell1608]

This is life changing info. I can't wait to get some material, and start up my mad scientist labratory, of building cool sh...stuff! 🤓 👍 Thanks!

[@UTubeGoNSoft687]

GO FOR IT!👍🤣🤟

Does Methylene Chloride require a specific applicator bottle? One that won't "melt"?

[@kronos6948]

I have used brushes with it. If you buy the stuff sold for models, it comes with a brush in a bottle. It's sold as Plastic Weld.

[@randallsemrau6911]

How do you whip that dispensing bottle around without dropping MC all over? I end up with blotchy plastic every time. Is the nozzle too large? What size nozzle is on that one?

[@chrissewell1608]

Where do you buy the Methylene Chloride at?

[@maximilianchen5231]

Would this method work the same way with simple lap joints or placing two polycarbonate sheets flat together?

[@jeffeastman8238]

what gauge needle are you using for your glue applicator? Thanks, Jeff

[@chrissewell1608]

Nice wood shop!

Hello! I was wanting to know I 3d print mostly in ABS, and I sometimes need to put pieces together normally I use ABS glue (mixture of abs filament and acetone) or just straight acetone, would weld-on 3 be a better option than the two I already use when joining piece together or does it depend on how it will be handled/used?

[@craziedde]

Makes me wonder if "Paint stripper" can be used as (methylene chloride or dichloromethane) replacement? From what I understand, "Paint stripper" is just a gel form of methylene chloride?

[@MrSloika]

Dichloromethane has been banned from use in consumer grade paint remover. You can still get dichloromethane paint remover but purchase and transfer is B2B only.

[@craziedde]

@@MrSloika hmm interesting, thank you for explanation

[@DJ_Switzer]

See Wikipedia page for Solvent Bonding for a list of plastics and related solvents. Unfortunately, no trade names provided.

[@chrispelletier3661]

Hello, thank you for your expertise. I am looking to see if you can laminate 2 thinner pieces of cast acrylic together to make a thicker piece? And if so how would you do this and what solvent to use. ( how would you keep from seeing air bubbles or gaps? Thanks Chris

[@RichardKinch]

Consider UV-activated optical cements (polyester) such as are used for cementing glass lenses.

[@sietsekerkvliet7751]

Are the welded joints watertight?

[@chrissewell1608]

Yes, they should be if welded properly.

[@davebarkerdesign]

Hi Mike, are the joints waterproof ?

[@chrissewell1608]

They should be, if welded properly! If not you could add a bead of silicone.

[@tomasbrosnan66]

Does it work on MABS?

[@boredape1257]

I'm very surprised that it works so fast. and that it is stored in such container.

[@joselinbenitez4296]

Where can I find that solvent?

[@modelmakers33]

As stated elsewhere on our channel, methylene chloride (aka DCM, or dichloromethane) is more likely to be available from your local plastic distributors than from hobby/craft stores. Brand names include: Rez N Bond, Weld-On, and EZFix(303) Always remember to be careful with these and other VOC solvents. They are volatile, toxic, and flammable. Don't breathe the vapors or get it on your skin, and don't use it near an open flame. Internet searches for methylene chloride may point you to certain paint strippers - don't try to use that.

[@RichardKinch]

@@modelmakers33 The products you mention also contain trichloroethylene (solvent) and methyl methacrylate monomer (cement), not just the methylene chloride solvent.

[@sangitakedia7159]

Is it is easily be formed?

[@MrWachowsky]

Please, if you use it wear proper PPE when handling and ventilate the room very well!

[@cedarcove28]

Came here to say the same. Read the data sheet! That skull and crossbones is there for a reason.

[@MoreEffinCowbell]

I agree! ...It seems as though he must practice Safety 3rd.

[@MoreEffinCowbell]

It's a solvent, not a glue! Stop referring to it as glue!
