ARADUR® 39

ARADUR® 39 is a waterborne amine curing agent designed for use in formulating two-component ambient-cured coatings without volatile organic compounds (VOC). It is supplied as a 50% solids solution in water and contains no organic solvents. ARADUR® 39 may be diluted with water down to 30% solids (wt.), but this may cause haziness. It is not suitable for use with solid resin dispersions due to insufficient coalescence of the cast films. In combination with liquid epoxy resins (e.g., ARALDITE® GY 9513 or PY 340-2), zero-VOC, fast-drying, and curing films with good flow and adhesion can be formulated.

Product Highlights

ARADUR® 39 Epoxy Curing Agent is designed for concrete primers and coatings with high water vapor transmission rates to reduce the incidence of blistering on floors that are continuously damp, such as in low-lying areas. Combined with liquid epoxy resins, it offers rapid curing at both low (e.g. 5°C) and normal ambient temperatures over a wide humidity range, and excel- lent adhesion to dry, damp or wet concrete. Its high chemical and stain resistance makes it ideal for self-priming concrete floor coatings and clear sealers.
