Sealing edges on dibond panels

[Robert Lambie]

Do you have a picture?

I would have thought the dibond has been guillotined, or have you had them ripped down to specific sizes?

could it be you have not cleaned the panel properly?
or perhaps
tension in your laminate thats been applied?
not left long enough for outgassing?

hard to tell doing it blind and without knowing full details.

Hi I didn’t take any photos.

Yes some of the panels were ordered in custom sizes so I’d imagine they used in house cutters

Left to outgas for over 24 hours.

Tension was a little heavy to keep the boards in place, as the laminator is between two benches.

Everything cleaned well.

The md5 was air release , could that be a issue ?

Has anyone tried a edge sealer ?

Thanks

If the print is heavy all the way out to the edge, you will have to leave it much longer than 24 hours to outgas before laminating. This is usually the cause of this problem.
Edge sealer might save your job if there is something to adhere to, the black polypropylene core of the dibond panels is not very stickable. Perhaps if you plane the front edge at 45 degrees with a hand plane to expose a bit of aluminium you would get a better result with that.

I usually find if I’m flood coating a panel (even if it’s just a coloured vinyl and not a laminated print) the vinyl tends to lift at the sides. I solve it by trimming away the vinyl from the very edge leaving a very small margin space (1mm or 2mm) around the perimeter

The print had very little ink coverage, so I thought 24 hours out gassing would be fine.

Cheers Phil , that was something I had in mind but good to know others use that method.

I was thinking cutting or sealing , but I think your right Simon the black part could be a problem when sealing

Thanks for your replies

Thats exactly what ive always done :bigsmile:

We’ve been edge wrapping for the last couple of years to solve this issue and dare i say it, give a more premium finish on composite panels. An extra 15-20mm all round and wrapped round the sides and stuck to the back.
Ideal for flood coats as it negates the issue of edges lifting or shrinking back due to a tensioned application.

Wrap it round the back and some 10mm strips of vinyl to hold in place,

or trim it 2mm shy of the edge if u don’t think a wee white edge will get you in trouble
