Compoundless Abrasive Polishing or Buffing Article
A compoundless buff and method of making a compoundless buff using a coating solution formulated with abrasive particles dispersed or suspended using a surfactant or suspension agent and which also contains a self-crosslinking acrylic binder emulsion that binds abrasive particles to nonwoven cloth of a buffing article when the coating solution is applied thereto forming a relatively hard abrasive-containing coating that enables the buffing article to abrasively treat a surface without having to separately apply any buffing or polishing compound. A preferred coating solution formulation further contains a lubricant emulsion that produces a lubricant and abrasive-containing coating of the buff having lubricant interspersed with binder and abrasive particles thereby reducing friction during buffing or polishing. A preferred coating solution also contains at least one surfactant to disperse the abrasive, suspension agent to keep the abrasive suspended, and buffering agent to keep the pH of the solution so it remains flowable.
FLEXIBLE ABRASIVE MEMBER HAVING ELONGATED DEPOSITS
A flexible abrasive member including a substrate, which carries an array of deposits with embedded abrasive particles, where each deposit has an elongated continuous structure that extends along a center trajectory predominantly in a longitudinal direction across the substrate. The structure has inset portions and recessed portions, which protrude oppositely along a transverse directions from the center trajectory. The inset portions of a deposit are accommodated in the recessed portions of a transversely preceding deposit, and the recessed portions of the deposit accommodate the inset portions of a transversely following deposit, so that the inset portions and recessed portions of neighboring deposits mutually overlap in said transverse directions.
Abrasive article
An abrasive article is provided which comprises a plurality of layers in the following order: a backing; an abrasive layer; a primer layer comprising clay particles, wherein the clay particles are agglomerated and form a layer; and a supersize coat comprising a metal salt of a long-chain fatty acid. The addition of the aforementioned primer layer can significantly reduce loading of swarf and improve both the cut and expected lifetime of the abrasive article.
LARGE DENIER NONWOVEN FIBER WEBS
Various embodiments disclosed relate to an abrasive article. The abrasive article includes a nonwoven web. The non-woven web includes a first irregular major surface and an opposite second irregular major surface. The nonwoven web further includes a fiber component comprising staple fibers having a linear density ranging from about 50 denier to about 2000 denier and a crimp index value ranging from about 15% to about 60%. The nonwoven web further includes a binder dispensed on the fiber component and abrasive particles dispersed throughout the nonwoven web.
ABRASIVE ARTICLE AND METHOD OF GRINDING
An abrasive article includes a backing, abrasive particles secured to the backing, and a size coat provided over the abrasive particles, the size coat comprises a binder resin, at least one filler material and at least one lubricant material having a melting temperature of at least about 200 degrees F. A method of grinding aluminum using such an abrasive article is also described.
Coated grinding means
A method for producing a coated abrasive includes producing or providing an intermediate abrasive product that comprises a substrate, a plurality of abrasive grains that are bonded to the substrate, and at least one layer of an uncured size coat that at least partially covers the abrasive grains with the uppermost size coat being uncured. The method further includes applying at least one grinding additive to the uppermost, uncured size coat with the grinding additive applied to the size coat in dry form. The method also includes curing the uppermost size coat. A coated abrasive is produced by the method and the coated abrasive is used to process a surface.
ABRASIVE ARTICLE AND METHOD OF USE
A coated abrasive article (10) having a flexible backing (12) and an abrasive coat (20) attached to the backing (12) by a tie coat (18), wherein the tie coat (18) is liquid-softenable such that the tie coat (18) maintains the flexible backing (12) in a substantially rigid state when the tie coat (18) is dry and allows the backing (12) to flex when the tie coat (18) is in its softened state.
Method for dry production of a sliding layer
A method for dry production of a sliding layer on a flexible backing, in particular a backing that includes a textile or an abrasive backing, includes at least the following. A binder, or more particularly an adhesive such as a hot-applied adhesive or a hotmelt, is applied to a flexible backing. The binder is applied in dry form, such as via scattering, and is joined to the backing via exposure to heat to form a sliding layer on the backing and to hold the sliding layer at least one of on and in the backing. A lubricant, or more particularly a lubricant that includes graphite or PTFE, is applied to at least one of the backing and the binder.
Flexible abrasive member having elongated deposits
A flexible abrasive member including a substrate, which carries an array of deposits with embedded abrasive particles, where each deposit has an elongated continuous structure that extends along a center trajectory predominantly in a longitudinal direction across the substrate. The structure has inset portions and recessed portions, which protrude oppositely along a transverse directions from the center trajectory. The inset portions of a deposit are accommodated in the recessed portions of a transversely preceding deposit, and the recessed portions of the deposit accommodate the inset portions of a transversely following deposit, so that the inset portions and recessed portions of neighboring deposits mutually overlap in said transverse directions.
Articles including polyester backing and primer layer and related methods
An article (100) has a polyester film backing (110) and a primer layer (120) including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester film backing (110). Another article includes a polyester backing (110), a primer layer (120) including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester backing (110), and a phenolic layer (140) disposed on the primer layer (120) on a surface opposite the polyester backing (110). The phenolic layer (120) can include abrasive particles (160). Processes for making the articles are also described, as well as methods for abrading a workpiece and improving adhesion between a polyester film backing (110) and a phenolic layer (120) on the polyester backing (110).
