Manufacturing of solvent-free acrylic pressure-sensitive adhesives in form of self-adhesive layers

Czech Z., Sowa D., Ragańska P.

International Letters of Chemistry, Physics and Astronomy

2013

Vol. 8, iss. 2

147-159

The present publication is related to a process for producing the non-solvent acrylic pressure-sensitive adhesive (PSA). New applications and technical specifications stimulate the continuous development of new methods of polymerization of solvent-free acrylate. New synthesis of solvent-free acrylics includes polymerization in the reactor with removal of the solvent and polymerization of the carrier. The polymerization process is connected with UV-crosslinking.

Studies on the photoreactive acrylic adhesives with high shrinkage resistance

Vol. 6, nr 4

Photoreactive solvent-based acrylic pressure-sensitive adhesives (PSA) present a new class of the products that offer a potential to produce a novel generation of ultraviolet cured self-adhesive articles with high performance and low shrinkage. A variety of solvent-based acrylic pressure-sensitive adhesives were prepared by a synthesis in the ethyl acetate with 50 wt.% solid content, based on 2-ethylhexyl acrylate, methyl acrylate, acrylic acid, N-vinyl pyrrolidone and the unsaturated photoinitiators: 4-acryloyloxy benzophenone, 2-hydroxy-1-[-(2-acryloyloxyethoxy)phenyl]-2-methyl-1-propanone, alpha-allyl benzoine, 4-acrylamidocarbonyl-dioxy benzophenone, p-vinyl benzophenone and 4-benzophenylvinyl carbonate. The main emphasis is placed on the influence of the photoinitiator concentration, the UV exposure time and the UV dose on the relevant PSA performance such as adhesion, cohesion and shrinkage on the coated PVC carrier.
