Abstract: The present disclosure relates to an abrasive article construction containing an anti-loading composition which significantly reduces loading, is coatable, is durable, and is relatively inexpensive to manufacture. In particular, the use of the anti-loading compositions of the present disclosure as a size coat at least reduces if not eliminates the need for a supersize coat, while offering comparable if not superior performance and durability. In one aspect, the present disclosure provides an abrasive article including a backing with a first major surface and an opposing second major surface, an abrasive layer bonded to at least a portion of the first major surface, with the abrasive layer comprising abrasive particles retained in a make coat. The abrasive article further includes an anti-loading size layer comprising a size coat binder and wax at least partially disposed on the abrasive layer and also includes a blocked acid catalyst.

Abstract: The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, and a photoinitiator. The polyvinylbutyral has a dynamic viscosity of between about 9 and about 13 mPA·s and a polyvinyl alcohol weight percent of less than about 18%. The polyurethane (meth)acrylate includes the reaction product of a diol, at least one diisocyanate, and a hydroxyfunctional (meth)acrylate or an isocyanatofunctional (meth)acrylate. When the optically clear, curable adhesive is placed between two transparent substrates and made into a laminate, the laminate has a haze of less than about 6%, a transmission of greater than about 88% and an optical clarity of greater than about 98% when cured. The optically clear, curable adhesive also has a peel adhesion of at least about 100 g/cm based on ASTM 3330 when cured.

Abstract: The present disclosure provides an abrasive article. The abrasive article includes a spunbond web. The spunbond web includes a first major surface and an opposite second major surface and a fiber component. The article further includes a binder dispensed on the fiber component. The article further includes abrasive particles substantially retained by the binder and dispersed about the first major surface of the nonwoven web and substantially forming a predetermined pattern.
