Microspheres are tiny sphere-like particles measuring between 10 and 250 microns in diameter. Though they are microscopic in size, the spheres are still much larger than the emulsion particles found in conventional adhesives like our Covinax line. This size difference has a dramatic impact on adhesive tack. The spheres create a discontinuous adhesive surface that limits physical contact with a substrate, resulting in easy removability and stable adhesion over time.

Emulsion adhesives use smaller particles that coalesce into a continuous film and do not always provide easy removal without damage or residue left behind.
