Chemical processing centre for the preparation and finishing of surfaces by ultrasonics and spray coating.

In its laboratory with specific equipment, NGL has an efficient team of specialists who study, formulate, develop, manufacture and market products used and recognised for cleaning processes in areas as varied as watch parts, jewellery, spectacles, optics, micro-mechanics, electroplating,, electronics and vacuum deposits.

NGL is always anxious to protect the environment and has made a name for itself as a leader in solvent-free preparation and finishing methods.

The development of hot-air, infra-red and vacuum-drying techniques make it possible to conduct complete aqueous-phase processes without oxidation of the surfaces and spotting. To this end, the laboratory offers an indisputable range of possibilities in the development of washing and drying processes appreciated throughout the world by everyone responsible for production:

• Time-saving preliminary tests, results and checks in the development of customers' projects¨
• Surface-cleanliness evaluation by analysis:
  
  • SEM (Scanning Electron Microscope)
  • particle counts
  • contact-angle measurements
  • nano-scratch tests
• process validation and homologation
• guidance and assistance in preparing specifications for capital investments.

Product biodegradability is one of NGL's prime research criteria. But while the manufactured product more than meets current standards, the used solution containing manufacturing pollutants must be treated.

That is why, in its department exclusively reserved for waste-water treatment, NGL offers a complete approach involving the preliminary study of the waste matter associated with installations such as pre-processing units or systems that precipitate impurities in the machining emulsions.
