Description:
Phenalkamine WV2103D is a unique type of epoxy resin hardener based on the latest modified Phenalkamine technology. It allow the formulation of solvent free epoxy coatings for steel and concrete primers due to it’s very low viscosity.
Advantages:
Excellent combination of rapid cure and long pot-life at both ambient and low temperatures（<5℃）.No solvent and high solids and ideal for formulating high solids or no solvent coatings. Excellent chemical tolerance and superior corrosion resistance. Excellent moisture tolerant during cure.

Caution: phenalkamine epoxy curing agents will absorb moisture and carbon dioxide when kept in opening containers. This may result in viscosity increase, darker color and some crystallization of the products. All containers of these products should be kept tightly when not in use and stored in a cool and dry place. Properly protected from moisture and air, this product has a shelf life of one year.
