Applications

  1. VIJ20557 can be used for solvent free surfaces tolerant floor coating primer.
  2. For pipe coating and metal tank coating.
  3. Excellent application as construction adhesive and transportation adhesive.

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.
