Aqueous Liquid FEP • Melt-Flow Low Porosity • Non-Stick & Corrosion Resistant

Everflon™ Techyours™
FEP Water-Based Series

Advanced water-based FEP liquid topcoats designed to provide exceptional non-stick release, chemical resistance, and corrosion protection. FEP melt-flows to form extremely low-porosity films for superior performance.

Melt-Flow Low Porosity

FEP melt-flows during baking to form an exceptionally dense film of very low porosity, making it ideal for low-abrasion release applications.

Corrosion & Chemical Barrier

Pigmented layers applied as mid-coats further improve permeation resistance across the entire multi-layer coating system.

Precise Film Build (Max 12 µm)

Recommended dry film thickness up to 12 µm (0.5 mil) per coat, with a minimum of two coats recommended for optimal barrier performance.

FDA & EU Food Contact

Grades like 460-300 and 460-303 comply with US FDA and EU Regulation (EC) No 1935/2004 when paired with compliant primer systems.

Aqueous Rheology & Melt-Flow Science

Homogeneous Suspension & Low-Porosity Sintering

Advanced aqueous stabilization ensures smooth atomization and dense melt-flow film consolidation during baking.

Axial Flow Impeller Mixing

Gently mix for 15 minutes or more using an axial flow impeller until contents are homogeneous. Adjust mixer speed so that a vortex appears while avoiding air entrapment. Insufficient mixing leads to application defects.

• Prevents settling and ensures defect-free films

200-Mesh Precision Filtration

Filter through a 200 mesh (approx. 75 µm) stainless steel or nylon screen before spraying to remove micro-agglomerates and maintain seamless flow through fine fluid tips.

• Guarantees flawless surface finish

Aqueous Clean-Up & Deionised Water

Equipment clean-up is effortlessly performed using water. Use deionised water as thinner or additive when adjusting application parameters.

• Eco-friendly water-based flushing

Application Method, Drying & Curing Schedules

Precision liquid spray parameters for aqueous FEP topcoats.

STEP 01

Coating Preparation & Mixing

Gently mix 15 minutes or more until homogeneous using an axial flow impeller. Filter through 200 mesh (approx. 75 µm) stainless steel or nylon screen.

STEP 02

RP / Conventional / HVLP Spray

Use RP (Reduced Pressure), conventional, or HVLP gun. Nozzle: 0.8–1.2 mm. Atomizing air pressure: 2–3 bar (30–45 psi). Max 12 µm DFT per coat (min 2 coats).

STEP 03

Drying Flash-Off

Dry coating for 10–15 min at 105–150 °C (220–300 °F) metal temperature to evaporate water completely.

STEP 04

Curing & Long Bake

Cure 20 minutes at 380–390 °C (720–730 °F) after each coat. Optional long bake (up to 90 min at 330–340 °C) enhances inter-coat adhesion and corrosion resistance.

Corrosion Barrier Systems

Using pigmented FEP grades (like 460-303 and 460-304) as mid-coats drastically improves permeation resistance and protects chemical processing equipment.

🔄

Low-Abrasion Release Rolls

Melt-flow FEP films form very low porosity surfaces, making them the natural choice for non-stick release applications with minimal mechanical wear.

🧪

Chemical Handling & Food Tanks

FDA-compliant clear (460-300) and black (460-303) topcoats provide exceptional chemical inertia for food contact and industrial vessels.

Storage & Aqueous Shelf Life

Gently mix (15 min at 30 RPM) before use. Shelf life is 12 months at optimal storage conditions: 18 °C–27 °C (65 °F–80 °F). Maximum storage temperature 40 °C (105 °F).

• Water-Based Dispersion: Protect from freezing (Transport 5 °C–40 °C)

• Gentle Agitation Required Prior to Spray Application

Ensure containers are securely sealed after use to prevent skinning and evaporation losses.
