Polymer Coating
Polymer coating is one of the major services we provide to complement our metal fabrication, offering high quality finishes. They work together to improve the quality, longevity and appearance of products made of steel, aluminum and other metal materials.
WHAT IS POLYMER COATING?
Since its early inception in the 1960s, polymer coating/powder coating has revolutionized the finishing process for a wide range of metal and fabricated products and has become a preferred alternative to wet spray painting. Powder coating/ Polymer coating is a dry process that entails the application of a colored powder. It works via electrostatic spray deposition (ESD).
Our metal polymer coating services are completed by experienced professionals who always strive to exceed expectations regarding quality, service and on-time delivery. We consistently meet the powder coating and fabrication needs of companies of all types and sizes in industries such as pharmaceutical, military and defense.
TYPES OF POLYMER COATINGS

-
PVDF (Polyvinylidene Fluoride)
WHAT IS HALAR® COATING?
Halar® ECTFE is a partially fluorinated semi-crystalline polymer offering a unique combination of mechanical properties, permeation resistance, thermal and chemical resistance, and versatility.
Halar® ECTFE is a melt processable fluoropolymer manufactured by Solvay Solexis. Its unique combination of properties is credited to its chemical structure, a 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene.
PROPERTIES OF HALAR® COATING
Halar® coatings provide outstanding chemical resistance. It is resistant to strong mineral and oxidizing acids, alkalis, metal etchants, liquid oxygen, and essentially all organic solvents except hot amines. Halar® coatings provide good electrical properties, a broad use temperature range from cryogenic to 300°F (150°C), meets the requirements of UL-94V-O vertical flame test in thicknesses as low as 7 mils (0.18mm) and in some cases meets USP Class VI and FDA food contact (21 CFR) requirements. It is a tough material with excellent impact strength.
Details :
-
Excellent resistance to strong acids (sulfuric, nitric, hydrochloric and hydrofluoric) over a wide temperature range
-
Resists strong bases such as sodium hydroxide and potassium hydroxide that would stress crack PVDF
-
Easily handles powder bleaching agents such as sodium hypochlorite
-
Resists strong polar solvents such as NMP and DMF
-
Not dissolved by any known solvent to 150ºC (300ºF)
-
Best radiation resistance of all fluoropolymers
-
Ozone-resistant
-
Excellent barrier properties, 10 to 100 times better than PTFE or FEP to oxygen, carbon dioxide, chlorine gas or hydrochloric acid
-
Excellent hydrogen permeation resistance
-
Low permeability to water vapor and other gases
-
Good electrical properties
-
Extremely low levels of metallic and organic extractable
-
Very low fluoride leach-out
-
Additional dynamic rinse data validate Halar® ECTFE as suitable for high purity systems in the semiconductor, biotech, and pharmaceutical industries
-
UL-94 V-0 vertical burn at 0.18 mm
-
Low flame spread, low smoke generation
-
Excellent mechanical properties over a temperature range from cryogenic to 150°C (300°F)
-
Excellent abrasion resistance
-
Nylon-like durability provides excellent impact resistance at ambient and sub-ambient temperatures
-
Excellent weathering resistance
-
Good tensile, flexural and wear-related properties
-
Extraordinary surface smoothness as measured by SEM and AFM
-
Significantly reduced bio-organic films and bacterial colonies compared to electropolished stainless steel and PVDF.
APPLICATIONS OF HALAR® COATING
Above characteristics have made Halar® the material of choice for many applications across multiple industries. It has been widely utilized in the chemical, pharmaceutical, and microelectronics industries for chemical resistance. Since 1990 Halar® powder coatings have been successfully used for corrosion protection of exhaust duct systems that must meet the FM 4922 fire safety standard. Halar® coatings have also been used to replace PVDF sheet linings in ultrapure water (UPW) systems.
As you can see, Halar® is a versatile material with almost limitless applications. Please contact us if you would like to learn more about Halar® coatings.
