Title: Adhesive Questions - Need Assistance
Post by: AlfaCh on March 15, 2012, 04:35:27 PM

1) How does one make spray aerosol pressure sensitive adhesive?

2) What kind of adhesive will adhere to HDPE (High Density Polyethylene)?

1) PSA + solvent + propellant.

2) You do realize that you are almost asking what will stick to Teflon? You do have a few options. 1) Use a rubber-based adhesive. 2) Corona or flame-treat the HDPE 3) Use a primer first, such as chlorinated PE.

Glad the answer was helpful.  Adhesive questions usually have lots of subtleties that can make answering questions about them difficult without having to write entire books.
