Some new adhesive options for xps and pmf?
Posted: Mon Feb 28, 2022 6:28 pmI recently came across a product called “Foam Fusion,” sold by https://hotwirefoamfactory.com in California. I was curious after watching this video:

I contacted them today to ask whether their adhesive may be appropriate for a Foamie camper build, and described the building methods and demands for an xps and pmf adhesive. This was their response:
Has anyone tried their adhesives yet?

The problem with Foam Fusion is that it takes a long time to dry when used with XPS foam, but after it dries the foam will tear before the glue gives. You should not glue directly onto the factory surface, it needs to be lightly sanded. Foam Fusion should work very well with your pmf system, as it penetrates most fabrics.
We have a new glue, FoamFast that worked super well with XPS, but does not work well with EPS, so we are blowing it out:

I have test pieces of DOW XPS Blueboard foam that I glued 3-4 months ago and when you try to pull the pieces apart the foam tears, with much force, but the glue holds fast. This is probably too pasty to work with your pmf unless you coat the foam, then squeegee the fabric in place.
StyroGoo bonds super well with XPS, so would be great for joints, but it's too pasty for your pmf.
Love what you are all doing with foam. Let me know if we can be of any further help.

… With almost any glue , the foam will always fail first … 
They even paid me for the inconvenience…
