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. Coating film can be reinforced and strengthened with a variety of mesh options when dictated by exposure conditions and service environments.
Special Qualifications
Series 118 meets the requirements of LEED-Low-Emitting Materials, Collaborative for High Performance Schools-Paints & Coatings, WELL Building Standard-VOC Restrictions, and Living Building Challenge–Healthy Interior Performance. Contact your Tnemec representative for more information.

Curing Time
| Temperature | To Touch | To Handle | To Recoat |
|---|---|---|---|
| 75°F (24°C) | 30 minutes | 4 hours | 8 hours |
Curing time varies with surface temperature, air movement, humidity and film thickness.
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.
