Everflon™ PFA Dispersion D450: Thermoplastic Coating & Bonding

Everflon™ PFA Dispersion D450 is the engineered solution for applications that demand the thermal performance of PTFE with the processing versatility of a thermoplastic. This off-white, aqueous dispersion allows engineers to coat, impregnate, and bond complex structures that would be impossible with traditional melt extrusion. It bridges the gap between processing ease and extreme environmental resistance.

Core Value Proposition

D450 is designed for extreme versatility. It functions not only as a high-performance coating but also as a premium hot-melt adhesive, capable of bonding PTFE to other substrates. Its ability to retain useful mechanical properties from –240°C to 260°C makes it indispensable in aerospace, chemical processing, and semiconductor applications.

Key Performance Pillars

• Hot Melt Bonding: Acts as a superior adhesive layer for laminating PTFE films or fabrics to metals and other high-temperature materials.

• Complex Geometry Coating: Ideal for spray or dip coating intricate porous structures where melt extrusion cannot reach.

• Thermal Stability: Matches PTFE’s continuous service temperature of 260°C (500°F) while offering a continuous, melt-formed film.

• Chemical Fortress: Provides a virtually inert barrier against nearly all industrial solvents and corrosive agents.
