acrylic adhesive

vames · 12/31/2009, 11:33 AM

I've been to every home improvement / hardware store in a 30-minute radius, without being able to find Weld-On or any methylene chloride based adhesives (which was recommended on some other site I found). All I was able to find was a loctite branded "Plastix bonder" which comes in a two part epoxy type plunger tube, and which I suspect is thick (and therefore won't be 'water-thin' and give me the capillary action I assume is critical) and a GE branded '100% Silicone Sealant" which comes in a toothpaste style tube with a cutoff plastic tip (cut to bead size). Does anybody know if either of these would be useable, or should I just buy Weld-on online somewhere (link?) ?

The application is simply gluing acrylic baffles in an acrylic wet/dry that I'm planning on using as my sump.

The Loctite product contain methyl methacrylate, which is probably the right material (acrylic is poly-methyl methacrylate, IIRC), but the GE brand was literally a shelf above the acrylic sheets @ Home Depot, and clearly meant for that application, but I've found nothing about what's in it...

Thoughts? Thanks.

The silicone will not work, the epoxy like you said will be very thick and you won't have very nice looking joints. I'm sure there's a place to buy The right stuff online

I just don't have a link for you. HTH
