Technical Datasheet 

VIJ 20558 is a low viscosity solvent-free Phenalkamine epoxy curing agent designed for epoxy coating applications protecting metal and concrete substrates. It has excellent rapid cure properties with high gloss even at low temperature and offers very good chemical resistance. It offers excellent adhesion on wet or unprepared surfaces and green concrete. Heavy duty industrial, protective, floor, potable water and marine coating can benefit from this products outstanding water resistance and corrosions protection.

Applications

  1. High solid coatings.
  2. Adhesives.
  3. Flooring and constructions.
  4. Marine and industrial coating.
  5. Surface tolerant primers for concrete and metallic.
  6. Excellent combination of rapid cure and long pot life at ambient and low temperature.
  7. Low viscosity for excellent workability.
  8. Moisture tolerant during curing.

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.
