In adhesives intended to be removable it's usually important to have high tack for good initial adhesion, but at the same time peel strength should be low and not build over time so the adhesive can be easily removed. Another important performance requirement is for clean removal of the adhesive with no ghosting or residue. The degree of carboxylation and the glass transition (Tg) of the polymer emulsion will all have an impact on the removability of the adhesive formulation. Non-carboxylated styrene-butadiene latexes tend to have limited adhesion build over time, making them a logical choice in removable adhesive applications.
