Title (EN) LIQUID ADHESIVE COMPOSITION, ADHESIVE SHEET, AND ADHESIVE BONDING METHOD
(FR) COMPOSITION ADHÉSIVE LIQUIDE, FEUILLE ADHÉSIVE ET PROCÉDÉ DE FIXATION PAR COLLAGE
Abstract:
(EN) An object of the present invention is to provide a liquid adhesive composition that, when cured, has a high degree of bond strength and exhibits a relatively constant storage modulus in a wide range of temperatures. A liquid adhesive composition containing (A) an acrylate-functional resin, (B) a hydroxyl containing (meth)acrylate, and (C) a silicone resin, the acrylate-functional resin (A) having a weight average molecular weight (Mw) of 25,000 to 100,000 and a Mw/Mn ratio of 2 or less, and the silicone resin (C) having a weight average molecular weight (Mw) of 450 to 2,000 and a silanol content of 0.1 to 5 wt.%, based on the silicone resin (C).
(FR) La présente invention vise à fournir une composition adhésive liquide qui, lorsqu'elle est durcie, présente un degré élevé de résistance d'adhésion, ainsi qu'un module de conservation relativement constant dans une large plage de températures. L'invention concerne donc une composition adhésive liquide contenant (A) une résine à fonction acrylate, (B) un (méth)acrylate contenant un hydroxyle et (C) une résine de silicone, la résine à fonction acrylate (A) présentant un poids moléculaire moyen en poids (Mw) compris entre 25 000 et 100 000 et un rapport Mw/Mn inférieur ou égal à 2, et la résine de silicone (C) présentant un poids moléculaire moyen en poids (Mw) compris entre 450 et 2 000 et une teneur en silanol comprise entre 0,1 et 5 % en poids par rapport à la résine de silicone (C).
