Deconstructing the Term: PVDF + Coating + Aluminum Coil

PVDF: The Heart of the Coating

PVDF stands for Polyvinylidene Fluoride. This is a high-performance fluoropolymer, a type of specialty plastic that is exceptionally stable and robust.

Its power lies in its chemical structure, specifically the strong fluorine-carbon (F-C) bond.

This bond is one of the strongest in chemistry, making it incredibly resistant to being broken down by environmental stressors.

Consequently, a PVDF coating provides a formidable shield against UV radiation, acid rain, pollution, and extreme temperatures.

It doesn’t just protect the metal; it preserves itself, ensuring colors remain vibrant and the surface remains intact for decades.

The Coil Coating Process: A Perfect Bond

The PVDF resin is applied to the aluminum in a highly controlled, continuous process known as coil coating.

Before any paint is applied, the aluminum coil undergoes a rigorous multi-step cleaning and pretreatment phase. This is crucial for ensuring maximum adhesion.

Next, a layer of primer is applied and cured. Following this, the PVDF topcoat, which contains the color pigments, is precisely applied and baked in an oven.

This process creates a uniform, flexible, and incredibly durable finish that is chemically bonded to the metal surface.

FAQs About PVDF Coated Aluminum Coil

To help you make the most informed decision, we have compiled answers to some of the most common questions about PVDF coated aluminum coil.

This section provides clear, practical insights into its use, maintenance, and specifications.

1. Is PVDF coating significantly more expensive than other coatings?

Yes, the initial investment for a PVDE coated aluminum coil is higher than for materials with Polyester (PE) or SMP coatings. However, it’s crucial to consider the total lifecycle cost.

PVDF’s exceptional durability means it will not need to be repainted or replaced for 20 years or more.

When you factor in the savings from drastically reduced maintenance, cleaning, and replacement costs, PVDF often proves to be the more economical choice in the long run for high-value projects. It is an investment in longevity and preserved property value.

2. What is the difference between 70% PVDF and other formulations?

When you see a specification for 70% PVDF, it refers to the percentage of PVDF resin within the solid part of the paint formula (the binder).

This 70/30 ratio (70% PVDF resin, 30% acrylic resin) is the industry’s gold standard for architectural coatings.

This specific formulation, used in premium products like those based on Kynar 500® or Hylar 5000® resins, provides the optimal balance for achieving maximum resistance to weathering, chalking, and fading.

Coatings with less than 70% PVDF will not deliver the same long-term performance and durability. Always insist on a 70% PVDF formulation for critical exterior applications.

3. Can you repaint a surface with a PVDF coating?

While it is possible, repainting a PVDF surface is a specialized task.

The very properties that make the coating so durable—its chemical inertness and smooth, non-porous surface—also make it difficult for new paint to adhere properly.

A successful repaint requires meticulous surface preparation, including thorough cleaning and the application of a special adhesion-promoting primer designed for fluoropolymer surfaces.

We always recommend consulting with a professional coating specialist to ensure the job is done correctly and the new finish will last.

4. How should I clean a PVDF coated aluminum surface?

Gentle cleaning is the key to maintaining a PVDF surface. The coating’s excellent resistance to dirt means aggressive methods are unnecessary.

For routine cleaning:

Start by rinsing the surface with clean water to remove loose dust and dirt.
If needed, use a soft cloth or sponge with a solution of water and a mild, non-abrasive detergent (like standard dish soap).
Thoroughly rinse with clean water afterward to remove any soap residue.
Crucially, never use abrasive cleaners, harsh chemical solvents, or rough scouring pads, as these can permanently damage the finish.

5. Is Kynar 500® the same thing as PVDF?

This is a common point of confusion. Think of it like this: PVDF is the generic chemical name for the resin (Polyvinylidene Fluoride), while Kynar 500® is a premium, globally recognized brand name for a 70% PVDF resin manufactured by Arkema.

When a specifier requests a coating with Kynar 500®, they are asking for the high-performance standard that guarantees top-tier weather resistance and color retention.

So, while not all PVDF coatings are Kynar 500®, all Kynar 500®-based coatings are the highest quality PVDF.

6. Is PVDF coating environmentally friendly?

The primary environmental advantage of a PVDF coated aluminum coil lies in its exceptional durability and longevity.

Because the coating lasts for decades without needing replacement, it significantly reduces the consumption of resources and energy associated with manufacturing, transporting, and installing replacement materials.

This long-service life is a key pillar of sustainable building practices.

Furthermore, the aluminum substrate is 100% recyclable, and the modern coil coating process is a highly efficient, closed-loop system designed to minimize waste and capture volatile organic compounds (VOCs).

Casting production process and its introduction

The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.

Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.

Hot rolling production process and its introduction

1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.

Casting and rolling process

Casting and rolling process: liquid metal, front box (liquid level control), casting and rolling machine (lubrication system, cooling water), shearing machine, coiling machine.

1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
3. The production speed is generally between 1.5m/min-2.5m/min;
4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.

Cold rolling production process

1. Cold rolling refers to the rolling production method below the recrystallization temperature;
2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.

Introduction to finishing production process

1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.
