Réticulation (polymérisation)Index. décimale : 668.3 Adhésifs et produits semblables Résumé : The developments in various formulation strategies and the types of UV curable PSAs available have been discussed.
It has also been recognized that UV PSA technology is still in its infancy and therefore a lot remains to be discovered. The library of raw materials is limited, as is the experience in an actual production setup.
Because the properties of the adhesive can be adjusted right up to the curing stage, there is currently no such thing as a standard radiation curable PSA. The chemistry must be adjusted to the process or vice versa.
Because chemical reaction takes place during curing, a good understanding of the process and chemistry and how these two interact is needed to make a consistent product.
A 100-percent conversion should be achieved in order to reduce residual monomers in the tape and to achieve a consistent product.
However, the recent developments in the warm-melt block polymer and the warm melt acrylate polymers have solved the problem of residual monomer and also provides an advantage over a conventional hot-melt PSA.En ligne : https://drive.google.com/file/d/1ulRcT1aOIKTVbUzQpbV_ZTJ7ztIXdXlR/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=19987
