Developments in the construction of high-solids solvent pressure-sensitive adhesives are enabling a range of new products and increasing the toolbox for formulators.
Sustainability is an ever-present driver for new products and applications. In pressure-sensitive adhesives (PSAs), sustainability is sometimes an underlying influence in the move from solvent- to emulsion-based products. This is not an option for all applications, however, as solvent-based PSAs give increased performance and processability compared to emulsion PSAs.
In a solvent-based PSA, the polymer enabled in the adhesive is more cohesive due to crosslinking, more chemically resistant, and can operate over a higher temperature range than a similar emulsion-based PSA. As a result, solvent-based PSAs empower more durable applications and find wide use across various markets, including building and construction, medical, tapes, and graphics.
