Coatings

Edlon’s series of fluoropolymer coating options has been engineered for resistance to chemical and mechanical damage in corrosive environments and high purity applications.  Edlon offers coatings in PVDF, ETFE, and FEP up to 40 mils thick, and in ECTFE and PFA up to 80 mils thick.

Our coatings are for use on virtually any metallic surface capable of withstanding processing temperatures (700-800F).  Coatings are field-repairable and can be applied to complex shapes through both manway and open access to both tanks and columns, which makes fluoropolymer coatings an excellent option for coating:

  •  Vessels
  •  Spool sections 
 
  •  Columns
  •  Protector rings
 
  •  Vessel covers and heads
  •  Storage vessels
 
  •  Agitators
  •  Transport tanks
 
  •  Baffles
  
   
 Coatings will withstand full vacuum and high speed agitation.  Our coatings are successful in many different chemical services, including caustics, acids, and organic solvents.  Please keep reading to find out coated mixermore about the specific coatings we offer.

 

ECTFE (Halar® or ethylene chlorotrifluoroethlyene)

ECTFE monomer 

Edlon’s SC-2001(TM) is a proprietary ECTFE-based powder spray composite coating.  SC-2001 offers excellent impact strength and abrasion and chemical resistance.  ECTFE is resistant to most acids, bases, and organic solvents at moderate temperatures and at higher temperatures to some select chemicals.  SC-2001 can be applied to complex shapes to a maximum thickness of 80 mils on interior surface and 10 mils on exterior surfaces.  As an exterior coating, ECTFE is superior to paint for resisting corrosion in harsh environments.

 

PVDF (polyvinyldifluoride)

  

PVDF monomer 

Edlon’s SC-3001(TM) is a proprietary PVDF-based powder spray composite coating.  SC-3001 offers superior resistance to abrasion and mechanical damage and to many corrosive environments.  PVDF is resistant to most acids and bases up to 150ºF and offers excellent resistance to bromine, as well.  SC-3001 can be applied to complex shapes to a maximum thickness of 40 mils on interior surfaces and 10 mils on exterior surfaces, including to the exterior of glass-lined equipment.  As an exterior coating, PVDF is superior to paint for resisting corrosion in harsh environments.  PVDF is manufactured by Solvay Solexis under the trade name Solef® and by Arkema under the trade name Kynar®. 

 

ETFE

(ethylene tetrafluoroethylene)

ETFE monomer 

Edlon's SC-5001(TM) is a proprietary ETFE-based powder spray coating.  SC-5001 offers superior resistance to attack by most chemicals and solvents at moderate temperatures.  SC-5001 can be applied to complex shapes to a maximum thickness of 40 mils on interior surfaces and 10 mils on exterior surfaces, including to the exterior of glass-lined equipment.  As an exterior coating, ETFE is superior to paint for resisting corrosion in harsh environments.  ETFE is manufactured by Dupont under the trade name Tefzel®.

 

FEP

(fluorinated ethylene-propylene)

FEP monomer 

Edlon's SC-6000(TM) is a proprietary FEP-based powder spray coating.  SC-6000 offers chemical resistance to most chemicals at moderate temperatures.  SC-6000 can be applied to complex shapes to a maximum thickness of 40 mils on interior surfaces and 10 mils on exterior surfaces, including to the exterior of glass-lined equipment.  As an exterior coating, FEP is superior to paint for resisting corrosion in harsh environments.

 

PFA (perfluoroalkoxy)

PFA monomer 

Edlon’s SC-7005(TM) is a proprietary PFA-based composite coating.  SC-7005 is engineered to have superior corrosion resistance, increased resistance to permeation, improved abrasion and scratch resistance, excellent release properties, and a superior bond to the steel substrate.  SC-7005 is inert to most chemicals except molten alkali metals and fluorine and certain halogenated compounds at elevated temperatures.  SC-7005 is also FDA compliant.  SC-7005 can be applied to complex shapes to a maximum thickness of 40 mils on interior surfaces and 10 mils on exterior surfaces, including to the exterior of glass-lined equipment.  As an exterior coating, PFA is superior to paint for resisting corrosion in harsh environments.

 

Fluoroshield®

Fluoroshield® is an FDA compliant, PFA-based dispersion (wet spray) coating.  These coatings use 100% melt processible fluoropolymers spray-applied to the substrate and baked after each successive layer.  Fluoroshield® offers near universal chemical resistance, superior resistance to mechanical damage, and performs well at elevated temperatures.  Fluoroshield® is field repairable and can be applied to most metals, except those alloys which contain a high copper content.

GSC-C

Fluoroshield® GSC-C utilizes a proprietary fusion layer between the metal substrate and the coating for a total thickness of 40 mils.  This intermediate layer provides the coating system with bond strength well in excess of that required to withstand full vacuum.

GSC-CS

Fluoroshield® GSC-CS utilizes the same proprietary fusion layer as the GSC-C to obtain the same fierce bond strength between coating and metal.  The coating in GSC-CS is filled with an intermediate layer of activated carbon which greatly enhances performance and longevity in vapor and liquid applications.  This coating has a total thickness of 60 mils. 

GSC-M

Fluoroshield® GSC-M is reinforced with a wire mesh for an even more tenacious bond between the coating and substrate.  The wire screen is welded to the metal substrate prior to coating; the fluoropolymer then flows in and around the wire mesh, resulting in bond strength greater even than the polymer’s tear strength and a thickness of 60 mils.

GSC-MS

Fluoroshield® GSC-MS combines the properties of both the GSC-CS and GSC-M coatings in order to achieve the best of both worlds.  GSC-MS is reinforced with a wire screen for a mechanically-bonded coating, while also containing an activated carbon layer to increase the longevity of the coating and mitigate the effects of permeation in even the most severe applications.  This coating is available in a total thickness of 80 mils.

GSC-CE

Fluoroshield® GSC-CE takes advantage of a static-dissipating graphite barrier.  This layer can be applied GSC-C, GSC-M, and GSC-MS systems.
