The invention pertains to a liquid composition comprising:
- at least one fluoroionomer (I) [fluoroionomer (I-1)], said fluoroionomer (I-1) having a heat of fusion comprised between 4 and 20 J/g;
- at least one fluoroionomer (I) [fluoroionomer (I-2)], said fluoroionomer (I-2) being substantially amorphous, that is to say having a heat of fusion of less than 4 J/g, and wherein the water extractable fraction of fluorionomer (I-2) is less than 40 % wt,
said liquid composition comprising fluoroionomer (I-1) and fluoroionomer (I-2) in a weight ratio (I-1)/(I-2) of at least 2:1. |
