Hello all,

We have been using 3M #45 Spray Adhesive at our sublimation business for many years. This appears to be no longer available. We do a lot of printing on hard substrates only and we go through a lot of spray adhesive (probably 4+ cans a week). We have tried other brands as a replacement but most of them leave splotches or "dots" on our materials, especially Chromaluxe aluminum. This is driving us crazy!

It appears 3M #45 and #75 are both non-existant in the US for purchase. I am not sure if its due to a shortage or them being discontinued. Does anyone have any suggestions for a good spray adhesive that will not affect printing. We are spraying very lightly and pressing immediately. I just want to find a good replacement that wont leave tiny imperfections in the finished pieces. This is requiring us to do a lot of re-work.

Thank you for any help!

Is your goal mainly to hold it in place before pressing, or to prevent it fluttering about when opening the press? If the latter, there are sub papers with adhesive that is activated by heat--obvioulsy of no use for the other purpose.

They probably nuked the old spray due to VOCs.
