This is probably going to depend a great deal on the application. How much PVC to acrylic, (what size, what weight, what thickness,) and what are the colors being used? PVC expands a great deal in the sun, especially with a dark color. Expansion differences of two materials such as these may require a more flexible adhesive.
Perhaps a bit more specific information would help Amy.

I want to make router cut letters with Chemetal faces. The Chemetal is normally laminated to acrylic or PVC. I am not trying to laminate PVC to acrylic. There is a lot of this used outdoors around here and I am wondering what type of contact adhesive is necessary for the outdoor application. I'm pretty sure normal contact adhesive like countertops use would be fine for indoor use.
Hope that makes more sense!

Most-if not all Chemetal Laminates are indoor use only. Especially the phenolis backed, but I believe all of them are indoor. I would contact Chemetal-I have used it on acrylic, but usually only use it on MDO or MDF for exhibit cabinets and panels for indoor interpretive panels for museums and store fixtures.

Chemetal laminates that don't have the wood back are for outdoor use. That's straight from Chemetal. I just can't get a clear answer on the adhesive. I need to call Jean & Roy Shimp. He told me before what he uses by 3M but I don't remember. I just don't have a need for a huge thing of adhesive that will go bad before it gets used and I was hoping to find something else.
Thanks guys.

I've had good results using silicone. (And I've had disastrous results using contact adhesive for exterior applications.)
The trick I found is to cut your metal laminate separate from your base substrate. When you assemble the metal to the plastic, lay a thick enough bead of silicone to "flex" with the inevitable thermal expansion differences.
Good luck!
BTW - you shouldn't be working on a Sunday. Go home.
