U-45 Solvent Base Acrylic Sealer
About the product
U-45 is primarily used as a clear sealer over concrete or cementitious surfaces due to its excellent wear and abrasion resistance. It is reduced in the field with xylene to achieve application viscosity; this is usually done at a ratio of 1:1 by volume. Solvents with low flash points (i.e., acetone) are not recommended to use as a reducing agent due to rapid evaporation rates; this can be problematic for both application and finish properties. A minimum of 2 coats is recommended for complete sealing of the substrate.
The coating installer should fully read and understand ICRI310.2R-2013 and OSHA 29 CFR 1926.1153 before starting preparatory work. The aim, of preparing a substrate for coating applications, is to roughen the surface, remove weak layers, contaminants, dirt, debris and present a solid, clean, dry substrate for the primer. If unsure as to the level of preparation needed contact Polymer Nation at techservice@polymernation.com
