Lesson Learned

[browders]

Apparently there's a difference between 3M Super 77 spray adhesive and Scotch 77 spray adhesive. I've always used the 3M version and have had good results. I recently purchased the Scotch version thinking it would be similar. Wrong thinking. I sprayed the back of the pattern placed the pattern on the taped board and started cutting. Prior to finishing my first cut the paper began to peel off the tape. The paper would not stick to the tape with the Scotch brand adhesive. It sticks fine with the 3M brand. Apparently there's a difference.

It seems like no matter what other spray adhesive I try, I go back to 3M 77.  That means they will be taking it off the market. Like so many other things I like to use.

It could be the one that came off is a removable adhesive or a repositionable adhesive as they call it. 3m is permanent. and it sticks well. I use it on all my shipping labels too.

The 3M77 is widely used in the automotive industry to glue labels on cars and also in the body shop we used to use it on the back of the sanding sheets to stick them to the sanding pads of our sanders.. This was back many years ago before self adhesive sanding papers became popular. 

I have tried many other brands etc.. and had success with them all for patterns.. however some of the brands required the spray to be very well sprayed and still wet when applied and others worked better when they were dried a little.. Also some cans need to be shaken up good and others really don't matter if shook up or not..

I have tried many brands of spray adhesive, but 3M77 beats them all. It sticks very well and is easily removed.

I ran out of my 3M spray awhile back and the I used a headliner (for autos) spray adhesive that I had left over and very old at the time. Well it worked great and really stuck to the tape/pattern. Not sure what brand it was and I am not recommending it but just saying when in need there is always a way. LOL

I ran out of 3M77 one time. My wife had a small 4oz can of Elmer's so I tried it. It worked great and I loved the small can. It didn't need much shaking either. I always use a heat gun for pattern removal and that worked well too. I still use the Elmer's but I have a can of 3M too.

I actually prefer 3M45 instead of the 77.. Best of all if a pattern will fit on a standard 8.5 x 11 paper then I prefer to print pattern on a full sheet shipping label.. Then it's just peel and stick to my tape or shelf liner covered board. No spray glue mess and no more clogged nozzles etc.

Although I prefer 3M77 I've used Elmer's also, and I like how it comes out in a fine mist. Seems to get more even coverage. 

Also, I think Scotch is owned by 3M, so it's weird that they would make a Scotch 77. Must be something in the formula.

3M make the same (or very similar) products with different part numbers for different divisions. I work in the automotive industry and we also sell to the industrial market. I often run into items that are the same product being sold with different 3M part numbers depending which division it is sold by

I have a bunch of half-sheet labels left after buying a laser printer. They work great.
