ARADUR® 38-1

• 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.

• 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.

• 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.

• Hazardous decomposition products (when disposed of in fire) carbon monoxide, carbondioxide, nitrogen oxides and other toxic gases and vapours.
• Mandatory and recommended industrial hygiene procedures should be followed whenever our products are being handled and processed.

ARADUR® 38-1 should be stored in a dry place, preferably in the sealed original container, at temperatures between 2 and 40°C. The product should not be stored exposed to direct sunlight. Stir before use.

Shelf life (at storage temperature between 2 - 40°C) - 3 years
