The present disclosure relates to a dielectric substrate that may include a first fluoropolymer based adhesive layer, a polyimide layer overlying the fluoropolymer based adhesive layer, and a first filled polymer layer overlying the polyimide layer. The first filled polymer layer may include a resin matrix component, and a first ceramic filler component. The first ceramic filler component may include a first filler material. The first filler material may further have a mean particle size of at not greater than about 10 microns.

Dielectric substrate and method of forming the same

The present disclosure relates to a copper-clad laminate that may include a copper foil layer, a fluoropolymer based adhesive layer overlying the copper foil layer, and a dielectric coating overlying the fluoropolymer based adhesive layer. The dielectric coating may include a resin matrix component, and a ceramic filler component. The ceramic filler component may include a first filler material. The dielectric coating may have an average thickness of not greater than about 20 microns.

The present disclosure relates to a dielectric substrate that may include a polymer based core film, and a fluoropolymer based adhesive layer. The polymer based core film may include a resin matrix component, and a ceramic filler component. The ceramic filler component may include a first filler material. The particle size distribution of the first filler material may have a Dof at least about 1.0 microns and not greater than about 1.7, a Dof at least about 1.0 microns and not greater than about 3.5 microns, and a Dof at least about 2.7 microns and not greater than about 6 microns.

According to one aspect, a composite film may include a substrate, and a protection coating overlying the substrate. The protection coating may include a urethane acrylate 6-functional oligomer, and a urethane acrylate 2-functional oligomer. The protection coating may further include a urethane acrylate oligomer ratio UAC/UACof at least about 0.5 and not greater than about 3, where UACis equal to the content of the urethane acrylate 6-functional oligomer in wt. % for a total weight of the protection coating and UACis equal to the content of the urethane acrylate 2-functional oligomer in wt. % for a total dry weight of the protection coating.

Composite film and methods of forming a composite film

The present disclosure relates to a multilayer film may include a fluoropolymer based layer that may include a fluoropolymer based material, and an adhesive layer in contact with the fluoropolymer based layer. The adhesive layer may include a first ultra-violet (UV) absorber component. The multilayer film may have a lower ultra-violet light transmission (L-UVLT) of not greater than 1.0%, where the L-UVLT of the multilayer film is defined as the percent transmission between 200 nm and 360 nm. The multilayer film may further have a high ultra-violet light transmission (H-UVLT) of not greater than 5.0%, where the H-UVLT of the multilayer film is defined as the percent transmission between 360 nm and 380 nm. The multilayer film may include a visual light transmission (VLT) of at least about 50.0%, where the VLT of the multilayer film is defined as the percent transmission between 400 nm and 1100 nm.

Multilayer film and method of forming the same

An abrasive article including a body including abrasive particles contained within a bond material, a first major surface, a second major surface, and a side surface extending between the first major surface and second major surface, and a coating overlying at least a portion of one of the first major surface or the second major surface. In an embodiment, the coating comprises at least one element selected from the group of chromium, nickel, carbon, nitrogen, tungsten, sulfur, molybdenum, iron, zinc, silicon, titanium, aluminum, zirconium, magnesium, zinc, boron, cobalt, calcium, or any combination thereof. In another embodiment, the coating comprises a cermet, a ceramic, or a combination thereof.
