Abstract: Various embodiments disclosed relate to an article. The article includes a first layer defining a first major surface of the article. The first layer includes a plurality of protrusions extending outwardly from the first major surface. The protrusions comprise an elastic polymer component. The article further includes a second layer opposite the first layer, which at least partially defines a second major surface of the article. The first layer is disposed over a range of about 5% surface area of the second layer to about 99% surface area of the second layer. The first layer and the second layer are in direct contact.

Abstract: Provided herein are abrasive compositions that use surfactants containing block copolymers of both propylene oxide and ethylene oxide moieties. Abrasive compositions derived from these copolymers were capable of providing both superior levels of cut rate while preserving a high quality surface finish on gelcoat surfaces comparable to those achieved using conventional rubbing compounds.
