The technology of solvent-borne pressure-sensitive adhesives (PSA) based on acrylic with post-crosslinking performance has been developed. The new synthesized acrylic PSAs contain monomers with oxirane groups or special monomers with post-crosslinking properties. They are applied for manufacturing of diverse self-adhesive products, such as: mounting tapes, splicing tapes, sign and marking films and structural adhesive tapes.

Opracowano technologię syntezy rozpuszczalnikowych klejów samoprzylepnych opartych na poliakrylanach z możliwością ich dosieciowania termicznego w podwyższanej temparaturze. Nowe kleje samoprzylepne na podstawie poliakrylanów zawierają grupy oksiranowe lub specjalistyczne monomery sieciujące. Po dosieciowaniu termicznym mogą być stosowane do produkcji taśm montażowych, taśm łączących, folii dekoracyjnych oraz adhezyjnych taśm strukturalnych.

The present report reports on the process of the removal of organic solvents in the polymerisation reactor, thin-layer evaporator, and twin-screw extruder for the production of the solvent-free acrylic pressure-sensitive adhesives (PSA). New applications and technical specifications stimulate the continuous development of new methods of manufacturing of non-solvent self-adhesives. The new synthesis of 100% acrylic systems includes solvent polymerisation and finally a removal of volatile organic compounds in a special extruder, polymerisation vessel or an industrial evaporator. The removal process requires controlling such relevant parameters as temperature, pressure and volatile organic compounds concentration.

The present paper discloses a novel photoreactive solvent-free acrylic pressure-sensitive adhesive (PSA) systems, especially suitable for the so much adhesive film applications as the double-sided, single-sided or carrier-free technical tapes, self-adhesive labels, protective films, marking and sign films and wide range of medical products. The novel photoreactive solvent-free pressure-sensitive adhesives contain no volatile organic compounds (residue monomers or organic solvent) and comply with the environment and legislation. The synthesis of this new type of acrylic PSA is conducted in common practice by solvent polymerisation. After the organic solvent are removed, there remains a non-volatile, solvent-free highly viscous material, which can be processed on a hot-melt coating machine at the temperatures of about 100 to 140°C.

Pressure-sensitive adhesives (PSA) present an interesting class of products that offers a potential to produce a novel generation of self-adhesives with a great number at excellent properties. The term pressure-sensitive describes adhesives that are aggressively and permanently tacky in the dry form at room temperature and firmly adhere to a variety of dissimilar surfaces upon mere contact, without the need of more than finger or hand pressure. Acrylic self-adhesive polymers are nowadays synthesized from a wide selection of acrylic ester monomers, often with low levels of monomers having pendant functional groups. The three basic types of acrylic common today are solvent-borne, water-borne, and solvent-free acrylic PSAs. They can be used in the production of single- and double-sided self-adhesive tapes, foil labels, carrier-free tapes, self-adhesive bioelectrodes, and decorative PVC signs and marking films. A pressure-sensitive adhesive requires a balance of cohesive strength and viscoelastic properties. These characteristics are based on three parameters: tack, adhesion, and cohesion.
