Abstract
A method for producing a surface coated with a coating having an improved coalescence, the method including: providing a composition comprising from 99.6% to 99.99% by weight of at least one powder of at least one polyarylene ether ketone and 0.01 to 0.4% by weight of a hydrophilic flow agent, the hydrophilic flow agent being hydrophilic silica; depositing the composition onto a surface forming a coated surface; and baking the coated surface to form a film on the surface.
