Frimpeks® launches a new range of self-adhesive substrates with a removable microsphere arcylic adhesive type.

November 19, 2015

Frimpeks® launches a new range of self-adhesive substrates with a removable microsphere arcylic adhesive type. It’s so sensitive it can adhere to extremely thin papers and peel without tearing the paper or leaving a residue.

Essentially the adhesive contains tiny little beads that sit on the surface of the adhesivDr Jernej Kajtna, Business Development Manager for Frimpeks® Europee when in contact with the labelled product. Dr Jernej Kajtna, Business Development Manager for Frimpeks® Europe explains the technicalities. “The main difference in the performance of microsphere suspension–based and emulsion-based PSA’s is the different particle size distribution (PSD) of material produced by the respective synthesis process.

The PSD drastically affects the characteristic of the film formed by the PSA upon its application. In emulsion systems, the fine adhesive particles, when dried, coalesce to form a continuous film. This smooth adhesive film in prolonged contact with a surface will increase in tack and peel strength with time. In the case of the microsphere adhesive, the adhesion arises from the physical structure whereby the formed film is discontinuous and spheres are in contact with the surface only at their tops, which causes lower peel strength, but also improves their removability.”

Frimpeks® Microsphere PSA consists of spherical polymer particles in the 3 – 30μm range. This type of adhesive is best described as niche speciality and can be used in a variety of products. Peel adhesion is retained after being repositioned. Lower peel values are seen as compared to standard emulsion adhesives.  They remove cleanly from a wide variety of substrates and the adhesive is also UV stable.
