An abrasive article includes a polymer binder, an infrared radiation absorbing dye, and abrasive grains. In particular embodiments, the abrasive articles have been at least partially cured using infrared radiation. The abrasive articles of the present invention can include, for example, coated abrasives, structured abrasives, and bonded abrasives. Mthods for manufacturing abrasive articles include at least partially curing an article that includes a polymer binder precursor, an infrared radiation absorbing dye, and abrasive grains using infrared radiation.
L'invention concerne un article abrasif qui comprend un liant polymère, un colorant absorbant le rayonnement infrarouge et des grains abrasifs. Dans des formes de réalisation particulières, les articles abrasifs ont été au moins partiellement traités par rayonnement infrarouge. Les articles abrasifs de l'invention comprennent par exemple des abrasifs appliqués, des abrasifs structurés et des abrasifs liés. Les procédés de fabrication d'articles abrasifs comportent l'étape consistant à traiter au moins partiellement par rayonnement infrarouge un article comprenant un précurseur de liant polymère, un colorant absorbant le rayonnement infrarouge et des grains abrasifs.
