Anyone work with Lexan?

Rate this topic

Do you need to use a special glue for Lexan or can you use CA glue?

I am in the process of making a permanent dust hood for my duplicator and want to use Lexan to make the cage. My proto is plexi but Lexan is stronger so I would like to use it instead. Thanks

View PostTry pvc cement, the stuff that really stinks. It bonds real well, but I dont know if it would adhere to lexan the same.

I use devcon 2 ton on lexan lips. Scuff the part that inserts into the plug, then add epoxy. Not sure if something similar would work for your application or not.

I'm looking to build a box with 4 sides of lexan going around a wood top where the Lexan will be screwed into the wood. I need to bond the edges of the lexan to each other as there will be no bottom. I think they make some kind of adhesive that fuses the lexan by partially disolving it but I'm not sure where to get it. I was just wondering if anyone had any success with a more readily available adhesive.

I used to use methelyne chloride back in the late 80's. Took me a minute to remember what it was. A quick search revealed the following:

 

 

Virgin polycarbonate is glued with and soluable in methylene chloride!!!

The problem is that virgin polycarbonate is almost never encountered!! All

polycarbonate normally distributed is specially coated and treated to

prevent scuffing and scratching. This tough and tenacious over-layer is

impervious to all known solvents and this standard material is un-gluable.

Period! It can be specially fusion welded (expensive) or bolted together

(most normal). * note* virgin polycarbonate when glued with Methylene

chloride forms a singularly, bubble free, flawless weld which is a marvel to

behold.

Have you considered getting some angle of plastic or aluminum and riviting it along the ends? It woudl be stonger than a chemical bond incase a piece flies off the lathe. I know the lexan is very strong (much better than plexi) that's why I use it for my bird wings.
