1- Or 2-Component Wash Primer (Formulation #4.1.1)

1- Or 2-Component Wash Primer (Formulation #4.1.1) is a guideline formulation used to exhibit the equivalent performance for SHIELDEX® anti-corrosive pigments compared to a commercial wash primer based on zinc tetroxychromate. The modified epoxy resin Beckopox EM 460 is recommended in combination with the standard polyvinylbutyral resin Mowital B 30 H to ensure good wet adhesion properties. Silquest A 187 Silane promotes wet adhesion properties especially on galvanised steel and aluminium.

The formulation can also be used as a one-component system. In this case, Part B is premixed and subsequently added to part A after dispersion. After mixing the two components and letting these prereact for a minimum of 30 minutes, the formulation was tested on solvent degreased cold rolled steel, galvanised steel and aluminium substrates applied to a dry film thickness of 10 – 15 microns by bar coater. The formulation was also tested with a 40 micron acrylic/isocyanate top coat.
