Epoxy primer 2K HS 1:1

Due to its premium-grade resins, the CP 394 primer delivers exceptional corrosion protection for steel surfaces. Notably, it exhibits excellent adhesion across diverse substrates, including steel, galvanized steel, aluminum, glass reinforced plastic, and existing paint coatings. Functioning both as a robust covering and filling primer, CP 394 also supports wet-on-wet application. Available in 0.8-Litre tins, it offers versatile application options and reliable protective properties.

Application

SUBSTRATE PREPARATION
Abrade substrate using a red P300-
400 abrasive pad by hand for steel,
galvanised steel or grey abrasive pad
for aluminium. Alternatively, P180-P240
sanding disc using orbital sander. Remove
dust particles before cleaning substrate
with CP 015. After the substrate is clean
and dry apply CP 394 with the required
number of layers, taking note of the
recommended evaporation time between
coats. Bake or airdry before progressing
to the next step of the process
