Series 118 | Uni-Bond Mastic

Generic Type Mastic Waterborne Acrylic
Common Usage A high-build, rust-inhibitive, elastomeric coating formulated for exceptional adhesion and corrosion resistance over minimally prepared aged coating systems. Series 118 is an excellent choice for projects where abrasive blast cleaning of the substrate is not possible and an anti-corrosive coating is needed. Uni-Bond Mastic accepts a variety of high-performance topcoats for the creation of a long-term protective and aesthetic coating system.

Volume Solids 55.0 ± 2.0% †
Recommended DFT 6.0 to 8.0 mils (150 to 205 microns) per coat. Note: Two coats are required over bare steel. Overcoating an aged system that is mostly intact and tightly adhered can be achieved by spot priming prior to applying a full coat.
