A method for producing a composite particle, the method containing: (a) mixing a raw material particle and at least one type of fine particles selected from SiO.sub.2 fine particles and Al.sub.2O.sub.3 fine particles, the fine paricles having a diameter smaller than that of the raw material particle; and (b) heating the mixture of the raw material particles and the fine particles, wherein the raw material particle contains three components of ZnO, Al.sub.2O.sub.3, and SiO.sub.2, and a content of the ZnO is 17 to 43% by mole, a content of the Al.sub.2O.sub.3 is 9 to 20% by mole, and a content of the SiO.sub.2 is 48 to 63% by mole, based on the total content of the three components.

The invention relates to an acrylic alloy composition that can be 3-D printed by a material extrusion additive manufacturing process, to an acrylic filament that has a very uniform diameter useful in the extrusion additive manufacturing process, to acrylic articles made from the acrylic alloy composition by a material extrusion additive process, and to a material extrusion additive manufacturing process for producing the acrylic articles. The acrylic alloy composition is an alloy of an acrylic polymer, and a low melt viscosity polymer, such as polylactic acid. The alloy may optionally be impact modified, preferably with hard core core-shell impact modifiers.

A pelletized road marking composition includes a binder mixture, a filler mixture and bentonite clay. The binder mixture includes at least one alkyd ester, at least one wax, at least one ethylene copolymer, and at least one plasticizer. The filler mixture includes at least one coloring additive, reflective elements, and at least one inert inorganic filler. The components of the road marking composition are mixed and melted and processed into pellets. The bentonite clay added to the composition prevents the pellets from clumping when stored at elevated temperatures.

A laminate structure and method of forming is provided. The laminate structure includes a first metal sheet having a first thickness, a second metal sheet having a second thickness, and an adhesive core having an adhesive thickness. The adhesive core is disposed between and bonded to the first and second metal sheets. The first and second metal sheets are made of an aluminum based material and the adhesive core is made of an adhesive material also described as a viscoelastic adhesive material. The laminate structure is configured such that a ratio of the sum of the first and second thickness to the adhesive thickness is greater than either to one (8:1). The laminate structure including the viscoelastic adhesive core is characterized by a composite loss factor at 1,000 Hertz which is continuously greater than 0.1 within a temperature range of 25 degrees Celsius to 50 degrees Celsius.

A polypropylene composition comprising the following components in parts by weight: 40-99 parts of a polypropylene resin; 15-30 parts of an ethylene-α olefin copolymer; 0.2-1 part of an antimicrobial agent; and 1-3 parts of a polypropylene grafted polydimethylsiloxane is provided. By controlling a melt index of an elastomer, distribution of the modified polydimethylsiloxane and antimicrobial agent can be improved, thus improving antimicrobial and stain-resistant effects of the polypropylene composition.
