WHAT IS TEDLAR?

RTP_Atrium_Tedlar_white_01.png

When DuPont researcher Roy Plunkett discovered the first fluoropolymer in 1938 it revolutionized the plastics industry. Exhibiting extreme resistance to known solvents, acids or bases, the breakthrough would give birth to widespread applications and countless products used throughout the world every day. DuPont went on to successfully polymerize vinyl fluoride (VF) in 1942, creating a new member of the fluoropolymer family, polyvinyl fluoride or PVF. that demonstrated enhanced mechanical properties that could withstand harsh and corrosive environments, resist UV light and repel water. Recognizing PVF’s unique potential as a film, DuPont trademarked its proprietary Tedlar® PVF Film in 1961 and introduced it for commercial use. Today, Tedlar’s steady chemical, physical and thermal properties continue to deliver superior protection to surfaces all over the globe from building construction and aerospace, to healthcare and transportation.

THE SECRET OF TEDLAR'S STRENGTH

The precursor of polyvinyl fluoride (PVF) is vinyl fluoride (VF), an organic compound of carbon, fluorine, and hydrogen. During polymerization, vinyl fluoride molecules combine to produce the polyvinyl fluoride polymer, a chainlike network of repeated VF monomers. Significantly, VF’s single fluorine, the most electronegative of all elements, draws electron density away from the linear carbon backbone, effectively creating even stronger bonds when repeated throughout the PVF polymer chain.

The resulting combination of unusual strength, chemical inertness and low permeability to air and water contributes to the superior performance of Tedlar against UV light, salt spray, pollution and harsh chemicals.

HOW IS TEDLAR DIFFERENT?

Tedlar outperforms all other types of protective metal coatings, including paint, in critical performance areas. This is a result of the film’s intrinsic chemical properties and physical properties as well as its unique formulation, finishing and adhesion process. 

 

Paints, for example, require the addition of co-resins or plasticizers to adhere to their substrate, manage flexibility or promote uniform coating or drying. These additives, however, are susceptible to UV and chemical degradation, while also imparting nutrients that can support microbe growth, thus compromising the substrate they are meant to protect.

 

TEDLAR FILM COMPOSITION: UNRIVALLED BALANCE OF DURABILITY AND FLEXIBILITY

Tedlar PVF film is made from just two primary ingredients: polyvinyl fluoride (PVF) polymer and pigments. The film’s formula does not require a tradeoff between native resistance and additives to facilitate processing, resulting in a more durable protective finish with unmatched resistance to corrosion from harmful UV rays, harsh chemicals, high heat and humidity.

100% PVF IS THE SOLE BINDER

that creates Tedlar and the central factor in its durability. Using only the highly stable polyvinyl fluoride matrix, the transparent and flexible film requires no additives to aid in processing, The film can be surface treated to accept a range of adhesives without additives keeping the exterior surface pure and maximizing performance outdoors.

INORGANIC PIGMENTS

with the highest level of inertness and durability provide color with the extra benefit of absorbing UV light and dissipating solar energy as heat. Gloss level is achieved using ceramic particles which roughen the surface for a smooth and matte finish that endures for many years.

STRETCHING AND FINISHING

are done using a biaxial stretching and drying process creating a dense molecular grid for additional mechanical strength, abrasion resistance and a smooth surface free of pinholes and other uneven formations. Extruded under DuPont’s strict quality standards, each batch of Tedlar PVF film is then certified to ensure that it meets the technical specs for metal substrate protection and batch-to-batch color uniformity. When finished, free-standing Tedlar PVF film can be stretched in any direction to more than twice its original length without cracks, loss of adhesion or color change. This superior formability and impact resistance compared with painted coatings make it an ideal choice for fabricating architectural metal building products. protection and batch-to-batch color uniformity. 

HOW IS TEDLAR APPLIED TO METAL?

Similar to paint-based protective metal coatings, Tedlar PVF film is applied in an automated, continuous fashion. Using flexible adhesives specially developed by DuPont for superior durability that resists moisture degradation, UV radiation and discoloration, the film is applied via a hot lamination process. 

How Tedlar is applied to Metal Roofing Panels

Lamination is accomplished by cleaning the metal, depositing a controlled conversion coating on the metal, coating metal with a solvent-based adhesive, evaporating the solvent, heating the metal to activate the adhesive, and then combining with Tedlar® PVF film in nip rolls and quenching the laminate.

Tedlar offers seven layers of protection

TEDLAR: An Unbreakable Bond

Once the application process is complete, Tedlar PVF film permanently becomes a part of the metal substrate. It will expand and contract with the underlying substrate during fabrication and temperature fluctuations when exposed to the environment. Even after extensive aging, Tedlar film cannot be removed, ensuring a low maintenance, durable structure with superior resistance to the wind, water, sunlight, hail, acid rain, chemical exposure and pollution.

QUALITY

WHAT’S DIFFERENT ABOUT TEDLAR COMPARED WITH OTHER METAL COATINGS?

Tedlar PVF film is superior to other protective coatings, including paint. With proven performance in the most  extreme environments, it won’t crack, blister or check from UV rays, corrosion, acid rain or dirt, and there will be virtually no color fade or chalking. Aluminum applications will not experience corrosion from sea water and salt spray, including on direct oceanfront properties. Tedlar is also impervious to harsh chemicals and can be  fabricated to the tightest of radii without cracks, loss of adhesion or color change.

 

AESTHETICS

I HAVE A LARGE PROJECT THAT REQUIRES A COLOR NOT ON THE CHART. HOW CAN I GET TEDLAR?

Stock colors are always the best choice for timely project completion, but on larger projects we can evaluate additional film and color choice availability to meet your needs. 

 

CAN I ORDER TEDLAR FINISHED METAL TO MATCH A TEDLAR PROJECT I DID YEARS AGO?

Yes! Due to the color uniformity of Tedlar film from lot-to-lot and the resistance to fading once installed, replacement metal panels or new panels for an addition can be ordered in the same color as the original order.
