Primers/Ship paints

The main purpose of primers is functional corrosion protection. The densely packed lamellar structure of the aluminium pigments in the coating layer greatly extends the diffusion paths for moisture and corrosive media, effectively protecting the coated metal from corrosion.

A typical application area for these types of primers are coatings for ships: Corrosion protection extends a ship’s service life and reduces costs (not only for the coating materials, but also, and primarily, for long layovers in dry dock).

EM

EM aluminium pastes are standard, white spirit-based leafing materials and come in a particle-size range of approximately 10-20 µm.

They are mainly used in decorative and industrial coatings and, in particular, for functional coatings which require a high degree of barrier protection (corrosion-protection coatings) or high light-reflecting properties ( e.g. roof coatings).

D 50 value [µm] Solid content Solvent Application
EM/110 13 65 +/- 2 % white spirit
EM/130 10 65 +/- 2 % white spirit
EM/70 20 65 +/- 2 % white spirit
EM/90 17 65 +/- 2 % white spirit

Polytop®

Polytop® are conventional, i.e white-spirit/aromatic-solvent-containing, non-leafing aluminium pastes.

A wide particle-size distribution ensures good covering power. They are referred to as “economy qualities” and are therefore chiefly used in general industrial coatings.

D 50 value [µm] Solid content Solvent Application
Polytop 0900 14 65 +/- 2 % white spirit
Polytop 0130 11 65 +/- 2 % white spirit
