POWDERY PRIMER COMPOSITION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18456591 titled 'POWDERY PRIMER COMPOSITION
Simplified Explanation
The patent application describes a powdery primer composition used in the production of a primer film for laminates. The composition includes a meltable fluororesin powder and polyethersulfone powder in a specific weight ratio. The meltable fluororesin has a specific melt flow rate.
- The powdery primer composition contains a meltable fluororesin powder and polyethersulfone powder.
- The weight ratio between the meltable fluororesin powder and the polyethersulfone powder is between 50:50 to 95:5.
- The meltable fluororesin powder has an average particle size of 5 to 100 μm.
- The meltable fluororesin has a melt flow rate of 0.1 to 50 g/10 min.
- The composition is used to form a primer film.
- The primer film is used in laminates that include a film containing a meltable fluororesin.
Potential Applications
- Production of laminates
- Coating applications
Problems Solved
- Provides a powdery primer composition for the production of primer films.
- Allows for the use of meltable fluororesin and polyethersulfone in specific ratios.
- Provides a specific range of particle size and melt flow rate for the meltable fluororesin.
Benefits
- Improved adhesion between films in laminates.
- Enhanced performance of the primer film.
