ECTFE Coating
ECTFE coating is a melt-processable fluoropolymer with a 1:1 alternating copolymer structure of ethylene and chlorotrifluoroethylene (ECTFE). As part of the fluoropolymer family, HALAR® coatings or ECTFE coatings have a unique combination of properties including excellent chemical resistance, good electrical properties, a broad-use temperature range, outstanding abrasion resistance, and excellent impact strength. ECTFE coatings resist a wide variety of corrosive chemicals and organic solvents, including strong acids, chlorine, and aqueous caustics making them ideal for vessels and process equipment for many industries including the petrochemical industry.

FEP Coating
FEP (Fluorinated Ethylene Propylene copolymer) coatings melt and flow during baking to provide smooth non-stick, non-porous films with excellent abrasion resistance. Because the coating is non-porous its chemical resistance is superb. FEP coatings can withstand a maximum use temperature of 205°C (400°F) continuously and intermittently up to 450°F. These coatings are chemically inert to most chemicals and solvents except very strong alkali solutions and fluorine at elevated temperatures. This coating is typically applied to a thickness of 1-5 mils DFT. FEP coatings are available in both water-based and powder forms for many application methods.

Molybdenum Disulfide (MoS2) coatings, also known as Moly Coatings are commonly used in applications where load carrying capacity, operating temperature and coefficient of friction are primary concerns. This coating provides effective lubrication in a wide range of loads, in many cases exceeding 250,000 psi. Moly coatings lubricate sacrificially by transferring lubricant between the two mating surfaces, which helps to reduce wear and coefficient of friction. Molybdenum Disulfide (MoS2) coatings are a dry film lubricant.
Moly Coating Properties
Moly coating is a combination of molybdenum disulfide lubricant and high performance resins. Molybdenum coatings are thermally cured and thoroughly bonded to the base metal of the coated part. Uses for molybdenum disulfide coatings include applications that require a lubricant that is more unreactive when in use, and remains sturdy.
Moly Coating Applications
Moly coatings have traditionally been applied on components subjected to high-pressures, whilst graphite coatings have been used in applications at high temperatures. Pre-treatment of the substrate, such as blasting to SA2.5, can have a marked effect on the end anti-friction quality of the component.
Dry-film lubricants like moly coatings are extremely useful for working parts which operate in an environment unsuitable for wet lubricants, or are positioned in awkward places that make wet lubrication very difficult. Different Molybdenum Disulphide coatings have variable degrees of corrosion and wear resistance qualities. The coating is suitable for heavily loaded mechanical applications, but not safe for food contact applications.
There are a number of application methods of MoS2 low friction coatings, including a simple rubbing or burnishing, air-spraying resin-bonded or inorganically bonded coatings, and more recently by sputtering through physical vapour deposition (PVD).

Powder Coating
The scale, geographical spread and capacity of our facilities mean we are able to reliably powder coat a wide range of components within tight turnarounds. Our powder coating processes are trusted by leading suppliers, precision engineers and OEMs in the automotive, oil and gas and aerospace sectors.
Why use Powder Coating?
Powder coating systems are extremely cost efficient. They rely on an electrical charge in both the work-piece and the paint material to ensure uniform deposition and minimal overspray and material losses, prior to heat curing. Powder coating offers durability and good corrosion resistance with exceptional levels of appearance and finish.
The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.
How does the Powder Coating System work?
Powder coating is the technique of applying dry paint to a part. The final cured coating is the same as a 2-pack wet paint. In normal wet painting such as house paints, the solids are in suspension in a liquid carrier, which must evaporate before the solid paint coating is produced. In Powder Coating, the powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
Key Properties

“White Goods”
Advantages of using Powder Coating
1. Powder coatings emit near zero volatile organic compounds (VOC).
2. Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
3. Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items.
4. The wide range of specialty effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.
TEFLON® Coating
TEFLON® is a trademark of DuPont™ used to refer to their non-stick products. TEFLON® coating is, by description, the foremost recognizable term used to describe PTFE or industrial performance coatings. It is a versatile product that is appreciated by many companies around the world for almost unlimited applications. Whether the requirement is for unique a configuration or a variety of geometric shapes, TEFLON® coating will always add value to a product, far beyond the inherent non-stick qualities.
TEFLON® coatings are manufactured providing a range of industrial coatings and are available in both liquids and powders. This coating is applied in a similar fashion to paint, however, when cured at the required temperature the coating becomes a tough and inert positive addition to the customer’s product. TEFLON® coating technology has an extended family of coatings, providing the ideal combination of performance properties that meets most of today’s design needs. By combining heat resistance with almost total chemical resistance, excellent dielectric stability and a low coefficient of friction, TEFLON® coatings offer the right balance of properties unbeatable by any other material
XYLAN® Coating
XYLAN® coatings differ from traditional fluoropolymer coatings in one very important aspect — they are composite materials. Lubricants with the lowest known coefficient of friction are combined in a matrix with the newest high-temperature organic polymers. These “plastic alloys” can be formulated to provide unique and desirable properties:

Controlled torque:
XYLAN® coatings are engineered with PTFE for lubrication, which allows precise and uniform makeup torque. (Stainless steel fasteners are prone to galling.)
Easy removal of nuts:
The lubricity of XYLAN® coatings makes removal easy — even after many years. Coefficient of friction is as low as 0.025.
Resistance to rust/corrosion:
Steel fasteners coated with XYLAN® over a zinc pre-treatment provide corrosion resistance almost equal to that of stainless steel. (They last as long as 2,500 hours in ASTM B-117 salt-fog tests with less than 15% red rust.)
Resistance to galvanic corrosion:
This occurs when two metals far from one another on the electromotive (galvanic) scale are joined by a conductor such as moisture. That frequently happens when stainless-steel fasteners are used with ductile iron, often employed in waterworks pipes and fittings. XYLAN® coatings reduce this corrosion. They also have a dielectric strength from 500-1,200 volts per mil (which inhibits galvanic corrosion).
Eliminates the need for toxic lubricating paste:
In fact, we recommends not using such pastes with XYLAN®-coated fasteners.
Tough:
Excellent resistance to wear, abrasion, chipping.
Cost:
Compared to stainless steel, XYLAN® coatings can save significant amounts (steel fasteners coated with XYLAN® cost an average of 50% less than stainless-steel fasteners).
Wide range of operating temperatures:
XYLAN® coatings operate easily from -255°C (-425°F) to +290°C (+550°F).
UV-stable:
Some XYLAN® formulations have superb resistance to ultraviolet light.
Resistance to hot soil:
XYLAN® helps protect fasteners from corrosion caused by hot soils and most common chemicals.
Easily applied:
XYLAN® can be applied by conventional spray, HVLP, electrostatic and dip/spin, making XYLAN® cost-effective for any size item, from large fasteners to small 0-rings.
Remarkable adhesion:
It adheres to a variety of substrates, including steel, aluminum, copper, stainless steel, brass, titanium.
Color-coding:
XYLAN® is easily color-coded for specific applications (to avoid confusion).
FDA-acceptable:
Many XYLAN® coating formulations comply with Food & Drug Administration regulations for food contact.
