Title (EN) HOT-MELT PRESSURE SENSITIVE ADHESIVE COMPOSITION HAVING REDUCED SENSORY IMPRESSION OF SMELL
(FR) COMPOSITION ADHÉSIVE SENSIBLE À LA PRESSION THERMOFUSIBLE AYANT UNE IMPRESSION SENSORIELLE OLFACTIVE RÉDUITE
Abstract:
(EN) The invention is directed to adhesive compositions containing 20 – 60 wt.-% of at least one styrene block copolymer, 25 – 70 wt.-% of at least one at 25 °C solid tackifying resin, and 0.1 – 20 wt.-% of at least one polyester polyol. The adhesive composition is especially suitable for use as a hot-melt pressure sensitive adhesive. The invention is also directed to a method for bonding substrates together using the adhesive composition and to the use of polyester polyols for reducing sensory impression of smell of adhesives containing 15 – 70 wt.-% of at least one styrene block copolymer.
(FR) L'invention concerne des compositions adhésives contenant de 20 à 60 % en poids d'au moins un copolymère séquencé de styrène, de 25 à 70 % en poids d'au moins une résine tackifiante solide à 25 °C, et de 0,1 à 20 % en poids d'au moins un polyester polyol. La composition adhésive est particulièrement appropriée pour être utilisée en tant qu'adhésif sensible à la pression thermofusible. L'invention concerne également un procédé pour lier des substrats ensemble à l'aide de la composition adhésive et l'utilisation de polyesters polyols pour réduire l'impression sensorielle olfactive des adhésifs contenant de 15 à 70 % en poids d'au moins un copolymère séquencé de styrène.
