Abstract
A coating technique for amorphous fluoropolymer involves adding amorphous fluoropolymer resin to a solvent. The resin solvent mixture is heated to a predetermined temperature above room temperature. The amorphous fluoropolymer resin is dissolved in a heated solvent, and the liquid coating solution is applied to a substrate. The solvent is then removed from the applied liquid coating solution. The coating technique may be employed in connection with liquid core waveguides.
Claims11
A coating technique, comprising:
- selecting an amorphous fluoropolymer resin;
- selecting a solvent that will dissolve the selected amorphous fluoropolymer resin;
- adding the amorphous fluoropolymer resin to the solvent;
- heating the resin and solvent mixture to a predetermined temperature above room temperature;
- dissolving the selected amorphous fluoropolymer resin in the heated solvent to form a heated, liquid coating solution having a viscosity less than about 5,000 cP;
- applying the heated, liquid coating solution to a substrate;
- and
- removing solvent from the applied liquid coating solution to form an amorphous fluoropolymer coating on the substrate.
