General Industrial Coatings – Solvent borne

Pigmentan products 465M, E, MX and EMX may be successfully used in solvent borne general industrial coatings at lower loading than existing anticorrosion pigments. They provide improved resistance to corrosion and lower cost on steel, aluminium and galvanized steel.

 

Pigmentan products are effective in short, medium and long oil alkyd based primers and phenolic or styrene modified alkyd Direct to Metal (DTM) coatings as well as in vinyl and acrylic coatings.It is important to consider the Acid Value of the alkyd in use. Alkyds with an Acid Value higher than 20 should be neutralised with approximately 0.25% by weight of a neutralizing amine such as AMP 95 or TEA to ensure a stable system.

 

As a general recommendation, Pigmentan 465M will be effective at 20 to 60% by weight of the loading of zinc phosphate or modified zinc phosphates in the system. Pigmentan E may be used at 20 to 50% of the original zinc phosphate loading.

 

In solvent based epoxy and PU formulations, Pigmentan MX & EMX are good direct replacements for zinc phosphate at 1:1 by weight for loadings up to 15% of the total formulation.

 

In new formulations the recommend loading of Pigmentan 465M is 2.5 – 4 % by weight on the total formulation and for Pigmentan E it is 1.5 to 3 % by weight (assuming formulations with 40-50% Non Volatiles by Volume).
