Default Airtak or Other Spray Adhesive

Where can I buy individual cans of Airtak? Have any of you guys used 3M 77 spray adhesive on epoxy rtm projects? What tactifier have you used with epoxy and how were the results?
Thanks in advance.

3m77 spray for me had no problems despite what others may think











Just some infusions i have used 3m spray it works well for me and iv read some bad reveiws about it personaly its down to preferance i use it light with not a a mark on demoulded items and Does not leave any residue what so ever. Its down to the user!! You pick up a paint guns and get runs dont blame the gun!!!

See what works best with you and your resin. If you get good results using airtak keep it its all about finding what suits your system best.

But I use 3M77 like Brainstorm and don't have problems with it either.

Thanks Brainstorm and Rotorage. Just getting ready to start some infusion and don't want to cause any more problems than necessary. I appreciate your help.

Use it lightly. I have seen problems with 3M77 or Super77, so I would not recommend it. It is easily available though.

I opted for the following:

-Airtac 2
-Ce-Sense Resin Infusion Spray Glue.

The latter has a nice report on effects in laminates.

Epock Z is the best for epoxy. Super77 is one of the worst. Not sure about V/PER resins though. The study is ongoing as well, but after several infusions and tests with various spray tacks, Epock Z came out on top for not effecting the performance of the part.
