Everflon™ Fluoropolymers

Everflon™ FEP D50.
Seamless protection, melted into precision.

Off-white aqueous FEP dispersion engineered for heat-sealable top-coats and chemical barrier coatings from -400°F to 400°F.

Flowable performance. Absolute barrier.

Designed to solve complex thermal bonding and anti-corrosion challenges.

Heat-Sealable
Lower Melting Point

Fuses at lower temperatures than PTFE, making it the premier choice for heat-sealable top-coats on PTFE glass fabrics.

Hot Melt Adhesive
Liquid Bonding Power

Acts as an effective liquid hot melt adhesive to bond PTFE, PFA, and FEP molded parts or film structures together.

Pinhole-Free Film
Superior Barrier Protection

Forms smooth, transparent, non-porous films that offer high chemical impermeability and non-wetting electrical isolation.

Non-Ionic Stability
Crack-Free Multi-Layering

Stabilized formulation allows precise thin-layer deposition (< 5 μm) avoiding mud-cracking during drying cycles.

Versatility crafted for high-stakes industries.

Empowering high-performance manufacturing across North America.

Heat-Sealable Top Coatings

Serves as a heat-sealable top coat over PTFE-coated glass fabrics for industrial conveyer belting, flexible expansion joints, circuit boards, and architectural membranes.

Chemical Barrier Cast Films

Casts ultra-thin, pinhole-free films that provide chemical impermeability for capacitor dielectrics, valve diaphragms, and ultra-pure chemical barrier linings.

Fluoropolymer Liquid Hot Melt

Functions as a reliable liquid hot melt adhesive layer to fuse PTFE, PFA, and FEP parts together during thermal consolidation processing.

Anti-Corrosion Metal Coating

Imparts anti-corrosion, chemical isolation, and release properties to metal substrates subjected to corrosive fumes or elevated temperatures.

Effortless processing. Controlled melt.

Compatible with dip, spray, spin, or roller coating techniques.

STAGE 01

Application

Apply thin coats (< 5 μm / 0.2 mil) per pass to avoid mud cracking during drying cycles.

STAGE 02

Drying

Evaporate water content at 120 °C (250 °F) prior to surfactant bake-off.

STAGE 03

Bake Off

Decompose non-ionic surfactant completely at 250–270 °C (482–518 °F).

STAGE 04

Consolidation

Melt-fuse particles into a continuous film above 280–310 °C (536–590 °F).

Scaled for industrial precision.

Packaged for safety, extended shelf-life, and seamless storage.
