The present invention relates to a composition that includes a PTFE powder, a surfactant, at least one of a polyalkylsiloxane, a polyalkylarylsiloxane, a fatty acid, a fatty acid salt, an alkyl- or alkyl aryl-fatty acid ester, a phosphate trialkyl or triaryl ester, an alkyl fluorosilicone, a C12-C40 alkane, a vegetable oil or a paraffin wax, and a salt. The present invention also relates to aqueous system that includes such composition and to uses thereof.

Powder composition

The present invention relates to an aqueous composition comprising at least one partially fluorinated copolymer in the form of particle powder, to a method for its preparation and to its use as a coating.

Coating compositions

The invention pertains to a fluoropolymer composition comprising: &#x2014;at least one fluoropolymer [polymer (A)]; &#x2014;at least one benzoxazine compound [compound (B)] of formula (I), wherein each of R, equal to or different at each occurrence, is H or a C-Calkyl group; Ris a C-Chydrocarbon group, possibly comprising heteroatoms, optionally comprising at least one benzoxazine group; j is zero or an integer of 1 to 4; each of R, equal or different at each occurrence, is a halogen or a C-Chydrocarbon group, possibly comprising heteroatoms, optionally comprising at least one benzoxazine group; &#x2014;at least one aromatic polyimide polymer [polymer (PI)]; &#x2014;at least one organic solvent [solvent (S)], and to a method for coating a surface, specifically a metal surface, with a fluoropolymer, using said fluoropolymer composition. 

Fluoropolymer composition

A fluoropolymer composition comprising: at least one thermoplastic partially fluorinated fluoropolymer [polymer (F)]; water; less than 15% wt (based on total weight of composition) of a water-soluble solvent mixture [mixture (M)] comprising: at least one alcohol solvent [solvent (A)]; at least one glycol derivative solvent having a boiling point of at least 100&#xb0; C. [solvent (GD)], wherein the solvent (GD) is a derivative of a compound comprising at least two hydroxyl groups, wherein at least one of the hydroxyl group has been derivatized to yield an ether or an ester bond.

Water-based fluoropolymer composition
