Stelpant PU-Alu Primer is a special primer based on a one component moisture-cured polyurethane resin binder. The product is suitable for the refurbishment of steel surfaces with old paint layers as well as old hot dip galvanized surfaces.

Due to the unique pigmentation, based on the barrier principle, it is developed for surfaces prepared by manual- or mechanical derusting. Stelpant PU-Alu Primer can be applied during unfavorable weather conditions, at temperatures up from -5°C and a relative humidity level as high as 98%.
