Technical Datasheet 

VIJ 20559(UW) is a low viscosity solvent-free with high solids content Phenalkamine epoxy curing agent. The highly hydrophobic aliphatic side chain of Phenalkamine hardener offers excellent water resistance, good flexibility, low viscosity, extended pot life and excellent choice for under water curing.

It has excellent rapid cure properties with high gloss even at low temperatures. It offers excellent adhesion on wet or unprepared surfaces.

Applications

  1. High solid coatings for under water curing.
  2. Marine and industrial coating.
  3. Surface tolerant primers for concrete and metallic.
  4. Potable coating for potable water tank lining and pipe coating.

Stability and Storage

Phenalkamine may absorbs moisture and carbon dioxide when left in open container, which could result in increased viscosity, discoloration, reduction of reactivity, and/or crystallization of the products. This products should be kept tightly sealed in their in original container when not in use, and store in a cold, dry place. Expiry of the products is six months from the date of manufacture.
