Auxiliary Materials and Supplies

We will gladly help you with a wide range of specialist auxiliary materials for the optical and precision mechanical industries, e.g. adhesives, casting resins, optical cements, lacquers, oils and greases.

All of this is supplemented by consultation services for the appropriate application of these chemical systems.

If you are interested, simply request our product catalog on chemical auxiliary materials and supplies. We will be happy to prepare an offer for you based on your particular application.

Our product portfolio of auxiliary materials and supplies includes:

  • Structural adhesives (up to 30 N/mm² endurance strength)
  • Sealants for low-strain embedding of optics in metal frames
  • Casting resin systems
  • Holding cements
  • Protective and optical edge lacquers
  • De-watering fluids and cleaning solutions
  • Optical cements for optical systems
  • UV-hardening optical cement systems and mount adhesives
  • Polish pitches on synthetic resin base
  • Instrument lubricants for the most demanding applications
  • Immersion oils with extremely low residual fluorescence and adapted refractive indices for microscopy and measuring technology
  • Polishing pads made of Desmopan (line and cross pattern)
  • Polishing pitches and adhesive cements
  • Polishing tools with pads of polyurethane foam 


We define auxiliary materials and supplies based on the following parameters, in order to ensure optimal and stable quality:

  • Pot life, mixing behavior, temperature application range, shelf life and storage behavior
  • Viscosity, Shore hardness, thickness, linear  thermal expansion coefficients, E and G moduli, glass transition temperatures, softening point, adhesive and tensile lap shear strengths, volume shrinkage
  • Climatic stability
  • Examinations on composition, formulation, solvent content, flash point and flow rating

Our methods for doing this (besides the other analytical examination methods):

  • Viscosity measurement
  • Dynamic heat-flow differential calorimetry (DSC)
  • Dynamic mechanical thermal analysis in tensile, bending, shear and compression modulus (DMTA)
  • Thermal expansion (dilatometry)
