Features & Benefits

Product Features
Product Properties
  • ARADUR® 38-1 contains no organic solvents. It represents an optimum solution in terms of high solids content combined with minimum hardener requirement.
  • When ARADUR® 38-1 is diluted with water, turbidity may occur. In pre-pigmented form, however, more stable hardener solutions can be produced.
  • In combination with suitable epoxy resins, relatively slow-drying films with good flow properties, good adhesion and a high gloss finish can be achieved. With (proportional) use of solid resin dispersions such as Araldite PZ 3961-1, drying times can be significantly shortened.
  • The pot life of dispersion coatings formulated with ARADUR® 38-1 is typically limited to a maximum of 1 - 2 hours (loss of gloss finish). A clear increase in viscosity occurs later especially in heavily diluted mixtures.
  • ARADUR® 38-1 being free of Nonylphenol was developped to succeed ARADUR® 38.

Applications & Uses

Product End Uses
Product Applications
  • Used with liquid epoxy resins such as Araldite® GY 776, or the emulsion PZ 33757/67, ARADUR® 38-1 is suitable for the formulation of water-dilutable coatings for application to mineral and metallic substrates.
  • Particularly suitable for solvent-free dispersion coatings with a high solids content.

Technical Details & Test Data

Mixing Ratio
  • The optimum mix ratio for Araldite PY 33757 and Aradur 38-1 is 100 : 85 parts by weight.
  • The optimum mix ratio for Araldite PZ 3961-1 and Aradur 38-1 is 100 : 15 parts by weight.
  • Dependant on application and required properties the use of only 80% of recommended hardener amount might be preferable.
