Definitions
- the invention relates to two-component binder systems which can crosslink on the basis of Michael-acceptor group-containing polymers and polymers containing amino groups.
- Such 2-component binder systems can be used for the production of adhesives, sealants or potting compounds.
- Two-component binder systems in particular based on polyols and NCO-terminated compounds, have long been state of the art. They are used for example in the metalworking industry, the automotive industry, the electrical industry, the packaging industry or the construction industry as adhesives, sealants, fillers or casting compounds (casting).
- a disadvantage of the polyurethanes bearing NCO groups as so-called hardeners is their sensitivity to moisture. When storing these compounds accordingly dense containers must be used. Also, as a rule, the polyol component must be carefully dried prior to mixing with the hardener component, otherwise a residual amount of moisture may result in undesirable blistering in the adhesive film which may cause disadvantages in end use.
- Another disadvantage of at least some binder systems based on two-component polyurethane adhesives is the toxicology of monomeric isocyanates, in particular volatile and / or easily migrating monomeric diisocyanates, in the hardener component.
- the migration of the migrates through the packaging material can lead to contamination of the packaged goods, on the other hand, depending on the amount of migratingem free monomeric polyisocyanate, long waiting times necessary before the packaging material is "Migrat-free" and may be used.
- Another undesirable effect which can be caused by the migration of monomeric polyisocyanates is the so-called antisealing effect in the production of bags or carrier bags made of laminated plastic films: Often the laminated plastic films contain lubricants based on fatty acid amides. By reacting monomeric polyisocyanate with the fatty acid amide and moisture, urea compounds having a melting point above the sealing temperature of the plastic films are formed on the film surface. This creates a kind of anti-seal layer between the film parts to be sealed, which counteracts a uniform seal seam formation.

To 20 g of this solution are then added 0.1 g PEI and the mixture homogenized for 1 minute. Using a spiral doctor (Erichsen), this mixture is then applied to a PET film and the solvent is evaporated by gentle blowing (about 3 min.). Immediately thereafter, a film CPP film whose surface was pretreated by corona, placed and pressed vigorously by means of a pressure roller uniform and bubble-free and stored at room temperature. From this film composite then 15 mm wide strips were cut out and the bond strength determined by means of a 90 0 C peel test on a tensile tester (Instron 4301). The withdrawal speed was 100 mm / min. After storage for 1 day at room temperature, a value of 10 N / 15 mm was measured and a demolition of the PET film was observed.
