3721

FiST 3721 is a fast drying, water-based acrylic one coat system (topcoat) that can be applied DTM (Direct to Metal) and provides protection in harsh, outdoor, unsheltered applications. The complex mixture of non-toxic, organic inhibitors offers protection that competes with most paints and zinc-rich primers. Provides multi-metal protection. Excellent UV resistance. FiST 3721 is weldable and can be used to keep surfaces corrosion free prior to welding. Can be matched to most custom colors. (clear only).
Application: Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, rust inhibitors, or any other surface contamination that could affect adhesion. For structural steel applications, Forgewat recommends a minimum of a NACE #3/ SSPC-SP6 commercial blast clean. Consult Forgeway and/or test system adhesion prior to full scale application.
Package:19 Litre pails, 208 litre drums, liquid IBCs and bulk.
