Pretreatment Primer

Pretreatment Primer offer clear advantages to the user as it offers excellent corrosion protection with a simplified process. Thus allowing high process cost savings.

Pretreatment Primer, as the name implies, combines two technologies into one single application step. Without the need for additional primer paint and with only a low dry film coating weight, our pretreatment primers offer excellent corrosion resistance.

The Gardobond® PC and Gardo® Protect processes also show very good adhesion to PUR foams and might therefore possibly replace the back-coat. The results are significant process cost savings and overall process simplification.

Chemetall’s innovative pretreatment primer technologies are ideally suited for a variety of metal substrates and are compatible with common paints, such as polyester, polyurethanes, PVDF, and epoxy, for two or three layer designs. Our Pretreatment Primer technologies are also available in colored and pigmented versions.
