This invention relates to cyanoacrylate-containing compostions that include, in addition to the cyanoacrylate component, a rubber toughening component, which is substantially clear and colorless and which is substantially free of release agents and anti-oxidants known to impair the fixture speeds and shelf life stability of cyanoacrylate compositions to which they are added. As a result, the inventive rubber cyanoacrylate adhesive compositions demonstrate improved properties, such as fixture speed, strenght and shelf life under accelerated aging conditions.
L'invention concerne des compositions contenant du cyanoacrylate qui comportent, outre le composant cyanoacrylate, un composant renforçateur, sensiblement clair et incolore et également sensiblement exempt d'agents antiadhérents et d'antioxydants connus susceptibles d'altérer les vitesses de fixation et la stabilité de la durée de conservation de ces compositions auxquelles ils sont ajoutés. Il en résulte que les compositions adhésives de cyanoacrylate de caoutchouc présentent des propriétés améliorées, telles que de vitesse de fixation, de résistance et de durée de conservation dans des conditions de vieillissement accéléré.
