Shot Blasting

The scale, capacity and locality of our facilities ensure we provide a cost effective and efficient shot blasting service. Shot blasting is used to prime and clean surfaces, removing rust, scale or old coatings to expose clean bare metal ready for subsequent treatment. It also provides an effective method of preparing a surface with a roughened profile which promotes the adhesion of the specialist coatings we offer. We are equipped to shot blast using a variety of media including; metal shot or ball, aluminium oxide, silicon granules and glass. These are specified to offer a wide range of surface conditions which optimize the performance of the finished deposit. For larger components and assemblies it can offer substantial speed and cost savings over other conventional cleaning methods.

Key Properties of Shot Blasting

  • Surface Cleaning – De-rusting / De-scale
  • Surface Preparation – Prior to coating

Pre-Coated Fasteners

We keep a huge stock of bolts, nuts and studs including 2H nuts and B7 studs. These fasteners are ready for dispatch worldwide in one day coated either with electroplating, PTFE/XYLAN, DACROMET® or GEOMET®. Sold to fastener distributors only in keg/box or pallet quantities, each B7 stud and 2H nut is tapped oversize for additional assembly ease.

Zinc Iron Plating

Zinc iron plating offers good corrosion resistance, typically 4 to 5 times better performance than Zinc plating and a deep, lustrous black appearance. It is used extensively in applications where its appearance is of key importance.

Key Properties for Zinc Iron Plating
• Corrosion Protection
• Typical Rack plated component with black passivate – 480 hours to White corrosion
• Consistent Black finish
• Abrasion resistance – harder than normal Zinc plating systems
Ductile

Zinc Tin Plating

Tin Zinc plating provides an extremely lubricious film with exceptionally good throwing power and exhibits exceptional corrosion resistance. The alloy of Tin and Zinc in the plated layer also provides galvanic corrosion protection of steel substrates when they are in contact with aluminium. The plated film is conductive and offers solderability where required. Tin Zinc Nickel is also incredibly ductile – components can be post formed by crimping and bending after they have been plated. Tin zinc is an ideal replacement for cadmium plating whilst not suffering from the harmful environmental impacts.

Key Properties for Tin Zinc Plating
• Corrosion Protection
• Typical Rack plated component with yellow passivate – 2000+ hours to Red corrosion (neutral salt spray)
• Ductile
• Temperature resistant
• Conductive
• Solderable
• Lubricious

Zinc Nickel Plating

Zinc nickel plating has the ability to offer outstanding corrosion protection, especially when subjected to high temperatures. It is used extensively in automotive under body applications where its temperature and corrosion resistance are vital.

The preferred alloy composition of zinc nickel plate is 12 – 15% nickel, with the remainder being zinc. This alloy gives exceptional sacrificial corrosion resistance and can be readily passivated. To achieve this alloy, zinc nickel is usually plated from an alkaline electrolyte.

Zinc Nickel is used to plate steel components when they are to be assembled with other dissimilar metals, particularly aluminium, and where there is a greater risk of galvanic corrosion. The plating layer is extremely ductile which enables pipe and tube assemblies to be plated prior to manipulation into their final shape. Its corrosion protection can be enhanced with clear, yellow or black Trivalent passivates.

Key Properties for Zinc Nickel Plating
• Corrosion Protection
• Typical Rack plated component with colour passivate – 1000 hours to White corrosion, 1500 hours to red corrosion (neutral salt spray)
• Ductility

Temperature Resistance
Abrasion resistance – harder than normal Zinc plating systems

Applications
• Automotive – Fluid transfer tubes which can be deformed into their required shape after plating
• Automotive – Fasteners, particularly in areas of high corrosion (under hood, chassis joints)
• Electronic – Connectors, as a direct replacement for cadmium to provide corrosion resistance and high electrical conductivity.
• Aerospace & Defense – joining components in contact with aluminium

Zinc and Zinc Alloys

Zinc plating offers an economical option for decorative and industrial finishes on metallic substrates. It is possibly second to only Nickel with respect to plating applications. Recent developments have focused on alloy plating of zinc with iron, cobalt etc. to produce exotic finishes with exceptional resistance to corrosion and high durability. Depending upon the practicality of your application, you can choose from a conventional high cyanide zinc plating process to the most modern chloride or other non-cyanide alkaline based processes which are, more recently preferred, for environmental reasons.

Zinc alloy plating involves using Zinc Iron or Zinc Nickel. Our experienced team will consult you on the optimum coating for your application and then expertly plate your material with a high-quality finish. The zinc layer is further enhanced with a range of Trivalent passivates which enhance the corrosion resistance of the plated layer. These are available in a range of colours – clear, yellow, olive drab and black.

Typical Applications for Zinc Alloy Plating
• Brake and Power Steering system pipes and assemblies
• Brake calipers
• Brackets
• Fuel pipes
• Rivets
• Connectors
• Hydraulic components and assemblies
• Machined components
• Fasteners

PVDF Coating

PVDF (Polyvinylidene Fluoride) coating or KYNAR® coating is a pure thermoplastic fluoropolymer that is non-reactive and possesses multiple coating benefits. It is a chemical resistant, thick film barrier coating primarily used on chemical processing equipment due to its low weight and low thermal conductivity. This coating is unaffected by most chemicals and solvents, and has excellent wear and abrasion resistance. PVDF coatings are especially resistant to solvents, acids and heat, and has low density compared to similar fluoropolymers. KYNAR® or PVDF coatings also have a high dielectric strength, excellent resistance to weathering elements in harsh environments. Along with the ability to self extinguish, PVDF generates little smoke in the event of a fire.

PVDF Coating Statistics
Thickness : 0.020″ – 0.030″
Use Temperature : 500°F max
Chemical Resistance (ASTM D543) : Excellent
Abrasion Resistance (ASTM D4060) : Excellent
Tensile Strength at Break (ASTM D638) : 6525 PSI
Coefficient of Friction (ASTM D1894) : 0.4 Static ; 0.3 Dynamic
Dielectric Strength (ASTM D149) : 260 Volts per mil
Hardness (ASTM D676) : 80 (shore D)

ETFE Coating

ETFE coatings are a copolymer of Ethylene and TetraFluoroEthylene better known as TEFZEL®. Although not fully fluorinated, ETFE coatings have excellent chemical resistance and can operate at 150°C (300°F). The resins within these coatings are the toughest within the fluoropolymer range and can be applied at film builds up to 1,000 micrometers. ETFE is available in powder form.
TEFZEL® or ETFE coatings are designed to give uniform thick or thin film coatings and are based on a modified ETFE. Changes in physical properties by radiation include reduced elongation while tensile strength remains unchanged. Stiffness is increased and electrical losses are increased. These changes are independent of whether radiation took place in air or nitrogen. In the case of flex life however, a difference exists in that radiation in nitrogen gives a greater flex life than an equal dose in air. This type of coating should be considered for a broad range of applications where you need the benefits of the qualities like high performance thermal, chemical and electrical properties as well as outstanding mechanical toughness.

Benefits
• Excellent chemical and heat resistance
• Good release properties
• First class cryogenic stability
• Low coefficient of friction
• Excellent electrical insulating properties
• Few substances will adhere to ETFE– tacky substances that do are easily removed
• Both oleophobic and hydrophobic – not readily wetted
• High dielectric strength and low dissipation factor
• Virtually unaffected by UV or weather
