Abstract: A method for the additive manufacturing of an elastomer part, includes—the creation of a model of spatial coordinates of the part; followed by—the corresponding deposition of an elastomer material. The deposition is carried out in a plurality of substantially flat layers which are vertically stacked. The elastomer material is deposited in the form of a latex-based liquid composition having a dispersion of polymers in an aqueous base, and the deposition is carried out by formation and pressurized ejection of drops of a liquid composition.

Abstract: The invention relates to a method for extracting high-quality polyisoprene by grinding plants via rotary shearing using a device comprising at least one rotor and at least one stator, into particles of size smaller than 1 mm, or grinding at a pH higher than 3 and lower than 8. This method is implemented in aqueous phase and allows the preparation of a dispersion of polyisoprene in water having a weight average molecular weight (MW) higher than 800 000 g/mol. The polyisoprene is extracted from plants and in particular from guayule (Parthenium argentatum). It is a method that is particularly heedful of the environment.

Abstract: The invention concerns a coating composition, in particular a paint comprising (A) 3 to 30 parts of a latex consisting of organic (co)polymers having a glass transition temperature ranging between −20° C. and 50° C.; (B) 0.05 to 5 parts of an epoxyfunctionalized polyorganosiloxane emulsion; (C) and 100 parts of mineral fillers.
