bonding acrylic sheet "stacked" instead of perpendicular?

[shrike]

I've seen in some sumps like the octo reef where acrylic is bonded to the front of the sump to outline the chambers or when the top brace appears to be 2 different color sheets bonded together. How is this done? I've tried bonding scrap pieces to clear acrylic with Weldon, only to leave a mess of air bubbles. has anyone ever done this, or is there a particular method?

Experienced member? He's a low effort attempt a tried but the air bubbles seem like an issue. If it's 2 colored sheets I don't think the aesthetic issues would show. I thought about just applying a tiny b bit around the edges but my concern is is that water could get trapped in between any gaps. I did some research and could not find any information about a method for doing this it's kind of hard to phrase or explain exactly what I'm talking about and it doesn't seem to be something commonly done.

In this picture I welded it to clear acrylic to be able to see what it looked like on the underside. I believe I was using well done three and both attempts but I'm beginning to wonder if there's some sort of different adhesive they would use for this.

Any advice or ideas are greatly appreciated thank you

He’s built a lot of acrylic tanks.

@Joe Glass Cages or @Tenecor Aquariums could also probably help out, I know there are some others with acrylic experience but can’t remember

There is a laminating adhesive that some people use. I have not used anything like that in years. I tried laminating thin acrylic as backgrounds for some experiments and they all bubbled over time. Lucky for me I experimented first and never offered them for sale. If you control Weldon 42 it might work.

@Troylee may be able to help.

Weldon 40/42 will give you a super clean lamination… if you use 40 you gotta let the mixture sit for several minutes and allow the micro bubbles to escape then pour it on and laminate you pieces together. It’s messy as it squeezes out around the edges but be will be a flawless lamination with correct clamping and weight distribution..

I have Laminated Panels on the Euro-Bracing and on the Side Panels. Perfectly Clear, I always wondered if they used Vacuum Pumps, and Vacuum Bags. Or if this was even possible with the Fumes from the Glue. At the Cabinet Shop, where I worked they Laminated Glued Plywood together, and used the vacuum system.
