Provided herein are surface treated pigments and methods of making and using the surface treated pigments. The surface treated pigments can comprise a mineral pigment surface treated with a hydrophilic latex composition and a hydrophobic material, which produce a film on an outer surface of the pigment. The hydrophobic material can be selected from a silane, a siloxane, or a siloxane/silicone resin blend, wax, fatty acid, styrene-butadiene latex, or a mixture thereof. The hydrophilic latex composition can be selected from a straight (meth)acrylic latex emulsion, a styrene-(meth)acrylic latex emulsion, or a blend thereof. The surface treated pigment has a surface energy that is less than a surface energy of the mineral pigment alone, a water contact angle of at least 90° and a dodecane contact angle of less than 150°.

This invention relates to manufacturing briquettes, pellets and shapes from recycled asphaltic limestone powder derived from waste residential roofing products. Briquettes and pellets are manufactured through a densification process at varying temperatures, creating recycled asphalt pellets, asphalt limestone pellets and bio mass and coal fines briquettes. Various shapes, including curbs and posts, are manufactured through heat and pressure in molds. Seawalls, walkways and wall panels are manufactured by blending asphaltic limestone powders with polymer resins and extruded or pultruded into shapes.

Provided is a method for preparing a modified filler. The method includes in sequence providing an acidified aqueous slurry of an untreated inorganic filler which has not been previously dried; an emulsifier material; and a hydrophobating agent having the following structural formula (I): (I) R.sub.a-M-X.sub.(4-a) wherein: R is C.sub.6 to C.sub.22 alkyl, M is silicon, titanium or zirconium, X is OR′ or N halogen, R′ is C.sub.1 to C.sub.4 alkyl, and a is 1; washing and/or filtering the acidified aqueous slurry to obtain a modified filler, and, optionally, drying the modified filler. Polymeric compositions and articles also are provided.

A filler for resinous composition is contained and used in resinous composition, and includes: a crystalline siliceous particulate material with a crystal structure made of at least one member selected from the group consisting of type FAU, type FER, type LTA and type MFI, and/or type MWW; and a surface treatment agent including an organic silica compound reacted with or adhered to a surface of the crystalline siliceous particulate material; the filler including the surface treatment agent in an amount falling in a range allowing the filler to exhibit a negative thermal expansion coefficient.

A fixing belt includes: a base having an endless shape; and a resin layer covering a surface on an inner peripheral side of the base, the resin layer comprising a resin and a filler, and having a second surface opposite to a first surface facing the base, the second surface having cell structures, and being roughened with the filler. When arithmetic mean roughnesses of the second surface in the central region X and the end regions Y and Z are defined as RaX, RaY and RaZ respectively, a difference between RaX and RaY, a difference between RaY and RaZ, and a difference between RaX and RaZ are all 0.1 μm or smaller, and a coefficient of variation of areas of the cell structures contained in each of the central region X, and end regions Y and Z is 25% or smaller.
