I was watching this video where a 0.045 mil air-permeable, double-sided adhesive tape was referred to:
It appeared to me to look like a 3M product.
I have been searching and have only found a one, single-sided “vented” 3M tape.
He is using the tape in a window lamination process. Can you tell me what product he might be using?
HuntsmanChemist, sorry for the late reply but the tape they are using does not appear to be a 3M tape. They reference an 0.045” thick air permeable tape which is applied to both glass panels. I assume based on this that it is an open cell foam tape. The doubling up of their tape would result in an 0.090” thick space between the glass panels.
If you are trying to laminate glass, people typically have used 4910 or 4918 clear VHB Tapes. Those are not “air permeable” tapes and people would have to leave an open area in the corner for air to escape as the liquid uncured resin fills the cavity. The “air permeable” taper in the video seems to address this.
