MELTABLE FLUORORESIN PRIMER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18456592 titled 'MELTABLE FLUORORESIN PRIMER

Simplified Explanation

The abstract describes a meltable fluororesin primer that includes various components such as FEP particles, a heat-resistant resin, surfactants, and water. The primer is used to form a primer film, which is then used in a laminate structure with a meltable perfluoropolymer film.

• The meltable fluororesin primer includes FEP particles, a heat-resistant resin, surfactants, and water.
• The FEP particles have a specific particle size range of 10 to 60 μm.
• The heat-resistant resin can be selected from polyamideimide resins, polyethersulfone resins, and polyimide resins.
• The ratio of FEP particles to the heat-resistant resin in the primer is between 50:50 and 95:5.
• The nonionic surfactant used in the primer is a polyoxyethylene alkyl ether surfactant.
• The meltable fluororesin primer contains 10 to 60% by mass of water.

Potential applications of this technology:

• Coating and protection of various surfaces, such as metals, ceramics, or plastics.
• Use in the manufacturing of electronic components, where a protective and adhesive layer is required.
• Application in the aerospace industry for coating and protecting aircraft components.

Problems solved by this technology:

• Provides a meltable fluororesin primer that can be easily applied and adhered to various surfaces.
• Offers improved heat resistance and durability compared to conventional primers.
• Enables the formation of a strong bond between the primer film and a meltable perfluoropolymer film.

Benefits of this technology:

• Enhanced protection and adhesion properties due to the combination of FEP particles and a heat-resistant resin.
• Improved heat resistance and durability, making it suitable for high-temperature applications.
• Simplified application process with the use of a meltable primer that can be easily melted and applied.

Original Abstract Submitted

A meltable fluororesin primer including a tetrafluoroethylene/hexafluoropropylene copolymer (FEP) particles, a heat-resistant resin, a nonionic surfactant, an acetylenic diol-based surfactant and water, wherein: the FEP particles have an average particle size of 10 to 60 μm; the heat-resistant resin is selected from polyamideimide resins, polyethersulfone resins and polyimide resins; the solid content mass ratio between the FEP particles and the heat-resistant resin is 50:50 to 95:5; the nonionic surfactant is a polyoxyethylene alkyl ether surfactant; and the meltable fluororesin primer contains 10 to 60% by mass of water based on the meltable fluororesin primer. Also disclosed is a primer film formed from the meltable fluororesin primer, a laminate including a film containing a meltable perfluoropolymer provided on the primer film, and a coated article including the laminate.
