01

Coatings

Coating of any vehicle is not just a one-step process, but involves many steps. Up to five layers of paint are applied to the surface of motor vehicles, be they passenger cars, trucks or buses. Coatings containing solvents protect vehicles from corrosion, abrasion, rust and other effects of weathering, while ensuring ideal optical surface properties such as polish or metal effects. Many different oxygenated or hydrocarbon solvents are used, ranging from esters and ketones to glycol ethers (in water-based systems) as well as aromatic hydrocarbon solvents are used in solvents blends for optimum solvency power and evaporation.

De-icing
& windshield wash

Solvents (alcohols such as isopropyl alcohol (IPA) or ethanol or glycols) are the main components of windscreen wiping fluid and ensure that the windows are kept clean, regardless of the temperature  while the vehicle is being driven. Deicers are part of windshield washing. These solvents must not damage the paintwork of the vehicle, nor attack other materials such as rubbers, sealants and trim.

03

Brake fluids

Solvents in brake fluids (mainly glycol ethers) are essential for driving safely. When you press your foot on the brake pedal,  the brake fluid transfers this force into pressure to the brakes and stops the vehicle.  Solvents ensure the brake fluid maintains a high boiling point, preventing dangerous vapour bubbles from forming and protecting your brakes by absorbing free water that can cause corrosion.

04

Electronic wires

Insulated wires are used in transformers, inductors, motors, generators, magnets and other applications requiring tight coils of insulated wire. They are also part of electronic equipment in vehicles. The manufacturing of winding wires involves a unique type of surface treatment using solvents. Electrical insulation layers (enamels) are applied onto the surface of copper wire (in some cases the conductor material may be a different metal like aluminium, copper-clad aluminium or brass). These insulation layers are applied for a variety of functional purposes, including a high and prolonged di-electric strength throughout the whole lifetime of the wire. The surface of round wires also needs a well-defined lubricant covering to ensure a good coiling performance and a smooth laying of the wire.

05

Tyres

Tyres are crucial to move both people and goods. On roads, just about everyone uses tyres: lorry and car drivers, cyclists and motorcyclists need them to move around smoothly and safely. Solvents help to make tyres stronger. Dearomatised aliphatic hydrocarbons with specific boiling point ranges are used to produce tyres. The solvent softens and cleans each rubber layer before the next layer is applied. Its adhesive properties help bind together the various components of the tyre, increasing safety and performance. Solvent-based adhesives keep the many different layers of material glued firmly together.

06

Train transport – cleaning

Solvents provide solutions for cleaning both the railcars and the rails themselves. The load of the cars determines which solvents are used to degrease, extract and clean them inside and make them shine outside.
