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.

Market & Specifications
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

GEOMET® Coating
The GEOMET® product range is a standard worldwide reference for industries requiring high performance thin layer anti-corrosion systems. GEOMET® products are completely chrome-free and capable of protecting a wide variety of metallic surfaces. The coatings are well suited for protecting both large and small parts, having either simple or complex geometry. In particular, GEOMET® coatings are a worldwide standard for use on fasteners.
GEOMET® is a proprietary water-based family of products containing metal oxides, metallic zinc and aluminium flakes. The zinc and aluminium platelets align in multiple layers forming a metallic silver film. Applied as a liquid, the coating is totally inorganic after thermal curing.
GEOMET® coating systems, which include silicate sealers – black and coloured topcoats – are applied to a variety of components to provide corrosion protection to ferrous metals including powdered metal parts.

• Cosmetic protection: the brake discs can be seen through the alloy wheels. The aluminium silver colour of GEOMET® 360 integrates perfectly with the style of alloy wheels.
• Braking behaviour: The low thickness of the coating on braking surfaces does not damage the quality of braking during the vehicle first use and enables a temporary protection of brake discs surfaces
• Temperature resistance (400°C): it enables to keep an excellent corrosion resistance on vehicles
• Protection inside the vents: no oxidation inside the fins – better thermal exchange while braking
• For after-market, GEOMET® enables to assemble the brake discs on vehicles without pre-degreasing (dry protection)
• The stronger corrosion protection of GEOMET® on the hub mounting surface makes brake disc dismounting easier

What is DACROMET®
DACROMET® is an aqueous solution comprising zinc in flake phase, aluminium metal powder and inorganic compound. It is normally treated by dip and spin coating of this aqueous solution followed by heat-treatment at a relatively high, that is, about 300°C temperature. As a result, 7-8 μm thick coating is formed by drying and curing during the hot air drying process. Metal zinc and aluminium, which constitute the coated film, can protect steel via self-sacrificing, namely, by inhibiting the corrosion of a given steel due to the electric activity of highly ionisable metal zinc. Here, the chromic acid in a polymerized state can control and inhibit the self-sacrificing of metal zinc thus serving the role of a binder while also establishing the passivation of coating, which then leads to inhibition of chemical reaction between zinc and iron and accordingly reduces the speed of corrosive progress, thus exhibiting high corrosion resistance. In addition, the zinc, aluminium flake and metal oxide, which are of multi-layered structures, can protect the surface of iron alternatively thus functioning as a barrier against external corrosive factors thereby exhibiting superiority in corrosion resistance.
