CONVERSION FROM SOLVENT-BASED TO WATER-BASED SEALANT

Water-based sealants are the golden standard in canmaking

Water-based sealing compounds are suitable for all types of cans for food, beer and beverages as well as general-line packaging.
They offer a wide range of benefits for the canmaker and society.
 
 

Benefits of water-based sealants


  • ENVIRONMENTAL BENEFITS
    Elimination of VOCs emissions, as the dispersion media is water.

  • HEALTH AND SAFETY
    Handling of water-based solvent-free materials.

  • TECHNICAL BENEFITS
    No recirculation and heating of sealing compound.
    Superior stability of water-based sealants.
    Reduced sealant build-up on lining equipment.
    Softer dry sealant film with reduced mechanical incidences in the seam.
    More homogeneous applied compound film.
    Best flavour characteristics, water-based sealants show better results on flavour testing.
    Superior film behavior in steam flow processes.

  • ECONOMICAL BENEFITS
    Less liquid material usage. 
    Higher material yield due to reduced film SG.
    No restricions and no special requirements for transport.
 

Investment in conversion from solvent-based to water-based technology is practically limited to an installation of a post heater (drying oven for ends) and change of metal parts in contact with sealant from colour metal to stainless steel.
