SP-33 ESD Pigmented Epoxy Coating
About the product
Product Overview
SP-33 is a pre-pigmented, electrostatic-dissipative, 100% solids epoxy. The coating provides electrical resistance in the range of 10^6 to 10^9 ohms, which remains consistent throughout the product’s service life. It can be ordered with two different hardener speeds—Standard and Medium—allowing users to accommodate both cold and warm weather applications and cure times. This eliminates the mixing time and mess often associated with color pack systems. SP-33 offers excellent hiding power, good flow and leveling, and outstanding toughness and flexibility. Once cured, the material exhibits broad-range chemical resistance as well as abrasion and impact resistance. SP-33 is compliant with ANSI/ESD STM7.1-2020.
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
Uses and Benefits
SP-33 is most often used in areas that contain equipment or instrumentation sensitive to electrostatic discharge (ESD), including but not limited to server farms, processing areas, clean rooms, and electronics manufacturing/assembly facilities. The recommended coverage is 80–100 sq. ft./gal (16–20 mils) of mixed resin. Multiple coats may be applied for higher build; the recoat window is 12–24 hours. If a second coat is applied after 24 hours, lightly sand or scuff the basecoat and then solvent-wipe with xylene to remove any loose dust or particles.
Note: Applying SP-33 too thinly can compromise its electrostatic dissipative properties and risk non-compliance.
Limitations
SP-33 is designed for application at 8 mils as a primer, 16–20 mils as a body coat, and 10–16 mils as a topcoat. Ideal application temperatures range between 60–90°F. Cooler temperatures will extend cure times, while warmer temperatures will shorten working and cure times. Verify that the substrate temperature is at least 5°F above the dew point during application and curing to avoid potential amine blush.
Color Variation
Tile Red and Warm Sun may appear slightly darker than other colors because they contain carbon black. This variation does not affect product performance or other key properties.

Mixing & Installation
Combine all of part A and B into a single container, large enough to accept the entire kit. Mix at 350 RPM for 2-3 minutes using an appropriate mixing blade and making sure not to introduce excessive air into the solution. Pour the entire content from the container onto the floor and follow normal squeegee and back roll techniques. To make an epoxy patching material mix no more material than can be mixed and applied within the stated Gel time and add the selected aggregate until the desired thickness is achieved. Recoat within 24 hours. Clean tools with a solvent similar to Xylene or Acetone.
