Protective Coatings – Solvent and Water borne Epoxy Primers

Pigmentan 465M and Pigmentan E are very efficient in solvent based epoxy primers while Pigmentan EA finds its use in high performance water based epoxy primers.

 

Generally, the replacement loading for Pigmentan 465M is of 40 to 60% by weight of zinc phosphate or modified zinc phosphates. Pigmentan E can replace them at 30 to 40% of the original loading.

 

In new formulations the recommended loading for good performance general purpose epoxy primer is 6-7% by weight on the total formulation for Pigmentan 465M and 2.5-3.5% by weight on the total formulation for Pigmentan E. (Referring to formulation with 50-60% Non Volatiles by Volume.

 

It should be noted that in epoxy primers it is possible to incorporate Pigmentan E and 465M both in the Hardener part (part B) and in the epoxy base (part A).
