SP-33 ESD Epoxy Floor Coating
SP-33 is a pre-pigmented, electrostatic dissipative (ESD), 100% solids epoxy.
Overview
SP-33 is a pre-pigmented, electrostatic dissipative (ESD), 100% solids epoxy. The coating provides electrical resistance between the range of 10^6 and 10^9 ohms which lasts throughout the life of the coating. It also eliminates the mixing time and mess inherent in using a color pack system. High-hiding, good flow and leveling, toughness and flexibility are characteristics of this high-quality epoxy. The cured material has good, broad-range, chemical resistance as well as good abrasion and impact resistance. SP-33 is compliant with ANSI/ESD STM7.1-2020.
Uses and Benefits
SP-33 is most often used in areas which contain equipment or instrumentation that is susceptible to electrostatic discharge. Areas such as these include but are not limited to: server farms, processing areas, clean rooms, electronics manufacturing/assembly and many others. The recommended coverage of SP-33 is 80-100 sq. ft/gal (16-20 mils) of mixed resin. Multiple coats may be applied to achieve higher build; the recoat window is 12-24 hours. If a second coat is applied after 24 hrs. of the first coat being applied, lightly sand or scuff the basecoat and then solvent wipe the surface with xylene to remove any loose dust or particles. ** Note** If SP-33 is applied too thin, the electrostatic dissipative properties will be diminished and will increase the risk of being non-compliant.
Limitations
SP-33 is designed to be applied at 16-20 mils as a body coat and 10-16 mils as a topcoat. Ideal application temperatures to be between 60-90°F. Cooler temperatures will increase cure times. Warmer temperatures will decrease working and cure times. Verify that substrate temperature is above 5 degrees of dewpoint during application and cure of material to avoid a potential amine blush. Note: Tile Red and Warm Sun appear slightly darker due to carbon black content.
Preparation
The preparation method for each project is determined by a full understanding of the substrate to be coated, the chemistry of the coating system being used, the coating system thickness, and numerous other factors. The coating installer should fully read and understand ICRI Guideline NO. 310.2R-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.

Mixing & Application
It is always recommended to mix the entire kit, whenever possible, to avoid off-ratio mixtures. Mix ratio is 2 parts SP-33 Part A to 1 part SP-33 Part B. Combine all of part A and B into a single container, large enough to except the entire kit. Mix using a 350 RPM mixer using an appropriate mixing blade for 1.5 – 2.5 minutes making sure to not introduce excessive air into the material.
Disposal: Dispose of material, containers, solvents, etc., per Federal, State and local guidelines, rules and laws.
