Title (EN) SILICONE-BASED PRESSURE-SENSITIVE ADHESIVE
(FR) ADHÉSIF AUTOCOLLANT À BASE DE SILICONE
Abstract:
(EN) Silicone-based pressure-sensitive adhesives, reaction mixtures used to form the pressure-sensitive adhesives, methods of making the silicone-based pressure-sensitive adhesives, and articles containing the silicone-based pressure-sensitive adhesives are described. More particularly, the silicone-based pressure-sensitive adhesives include silicone-based elastomeric materials that are prepared by polymerizing a silicone compound having at least two ethylenically unsaturated groups in the presence of actinic radiation (e.g., ultraviolet radiation) and a controlled radical initiator. The controlled radical initiator is a bis-dithiocarbamate or bis-dithiocarbonate compound having a single carbon between the two dithiocarbamate or dithiocarbonate groups.
(FR) L'invention concerne des adhésifs autocollants à base de silicone, des mélanges réactionnels utilisés pour former les adhésifs autocollants, des procédés de fabrication des adhésifs autocollants à base de silicone, et des articles contenant les adhésifs autocollants à base de silicone. Plus particulièrement, les adhésifs autocollants à base de silicone comprennent des matériaux élastomères à base de silicone qui sont préparés par polymérisation d'un composé de silicone ayant au moins deux groupes à insaturation éthylénique en présence d'un rayonnement actinique (par exemple, un rayonnement ultraviolet) et d'un initiateur radicalaire contrôlé. L'initiateur radicalaire contrôlé est un composé de bis-dithiocarbamate ou bis-dithiocarbonate ayant un atome de carbone unique entre les deux groupes dithiocarbamate ou dithiocarbonate.
