The present invention is directed to a process for preparing coating compositions containing up to 100% bio-based content. The coating compositions are used for coating metal, paper and wood substrates in various applications. The process for preparing the coating composition comprises the steps of providing lignin, wherein the lignin is agglomerated and has a particle size distribution such that at least 80 wt-% of the agglomerates have a diameter within the range of from 0.2 mm to 5.0 mm, dissolving the agglomerated lignin in an organic solvent, and mixing the solution with a crosslinker to obtain a coating composition.

A method of manufacturing a dandelion latex shoe component. Dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) are mixed together to form a first mixture. The dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) are mixed at a temperature not less than 60° Celsius and not greater than 80° to form the first mixture. Silicon dioxide is then mixed with the first mixture to form a second mixture. The silicon dioxide is mixed with the first mixture at a temperature not less than 80° Celsius and not greater than 100° Celsius to form the second mixture. The dandelion latex shoe component is then formed from at least the second mixture via a molding process.

The present disclosure provides an ultralow-glossiness, ultralow-temperature resistant ASA resin composition and preparation method thereof. The composition includes the following components in parts by weight: 20˜60 parts of an acrylonitrile-styrene-acrylate graft copolymer, 40˜80 parts of an acrylonitrile-styrene copolymer, 1˜20 parts of an ultralow-glossiness, low temperature resistant modifier, and 0.1˜5 parts of a processing aid. The ultralow-glossiness, low temperature resistant modifier includes a carrier copolymer, a fluorinated copolymer, a low-temperature flexibilizer, a coupling agent, fumed silica and an assistant. The ASA resin composition prepared by the present disclosure has an ultralow-glossiness, can be used to replace mold processing technology such leather marking and texturing, which greatly saves mold cost and processing production cost; and meanwhile it also has excellent low temperature resistance and can be applied in cases having requirements on low temperature resistance and low glossiness such as automobile parts, outdoor profiles, building materials and electrical appliances.

A method for manufacturing a fired body of a fluororesin includes a mixing step of mixing a fluororesin pulverized after firing and an unfired fluororesin powder aggregated after emulsion polymerization at a rate based on predetermined strength to produce a component to be fired, and a firing step of firing the component to be fired produced.

A method manufacturing a spacer for a pipe-in-pipe system includes mixing aerogel particles with a polymer to form a mixture in which the particles are dispersed in the polymer. The resulting mixture is moulded and the polymer is solidified to form the spacer or a component of the spacer, in which the dispersed, particles are suspended in a matrix of the solidified polymer.

A coated article is described, including a substrate with a coating composition applied thereon to provide a coated article with a textured surface. In one aspect, the coated article is a steel rebar used to reinforce concrete. The textured surface provides optimal surface roughness and demonstrates superior pullout strength relative to an uncoated standard.
