P-99

Product Overview

P-99 is a state-of-the-art Bisphenol F epoxy, Moisture Vapor Suppression (MVS) coating. As a Bis F epoxy, it offers greater functionality than Bis A epoxies, providing better chemical resistance to caustics and acids. This is critical when combating high alkalinity at the concrete/coating interface. P-99, when properly installed, forms a tight film that adheres tenaciously to concrete. This highly crosslinked film reduces the amount of moisture vapor that can pass from the concrete through the P-99. Independent testing, performed by CTL Labs, shows ASTM E96 test results of 0.074 grains per hour per square foot per 1 inch of mercury. This extremely low perm rating results in P-99 being classified as a Class 1 vapor retarder. P-99 comes in standard and fast set versions.

Uses

P-99 is used as a Primer when concrete testing per ASTM F2170 shows average RH readings above 75% or when moisture vapor emissions are suspected and an additional level of moisture-transmission protection is desired. When applied seamlessly at 16 mils over a concrete surface profile (CSP) of 2 or 3, P-99 will reduce moisture vapor transmission (MVT) to less than 0.1 perms, as shown in independent testing. P-99 is also used as a Chemical Resistant Build and Topcoat when a high-build epoxy with a broad degree of chemical resistance is needed, such as in battery charging stations, laboratories, and chemical splash and spill locations.

Preparation

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.
