Plural Component Coating
Heavy-duty, ultra-thick coatings applied with a specialized Graco two-component system — engineered for tank linings, internal pipes, frack tanks, and demanding containment environments.
What Is Plural Component Coating?
Plural component coating is a specialized application process that meters and mixes two (or more) material components — such as a base resin and a catalyst — at the point of spray. Unlike traditional single-component coatings, this system produces extremely thick, high-build films in a single pass, with rapid cure times and very short pot life.
The result is a tough, monolithic barrier that resists chemicals, abrasion, and immersion in ways conventional coatings simply cannot match. This makes plural component coatings the preferred choice for internal containment surfaces, tank linings, and any application where thick, fast-curing protection is critical.
Where we apply coatings
100% Solid Epoxy
A zero-VOC, high-build epoxy system that cures into an extremely hard, chemical-resistant barrier. Applied at high mil thickness in a single pass, it forms a seamless lining ideal for immersion service and aggressive chemical environments.
Best for:
Tank linings, secondary containment, chemical processing vessels, and internal pipe surfaces exposed to acids, alkalis, or solvents.
Polyurea
An ultra-fast-curing elastomeric coating that reaches handling strength in seconds. Its flexibility and impact resistance make it the go-to for high-abrasion and high-impact environments. Excellent waterproofing and crack-bridging properties.
Best for:
Truck bed liners, frack tank interiors, containment berms, bridge decks, and surfaces subject to heavy mechanical abuse or thermal cycling.
Polyurethane
Best for:
Pipe interiors, storage tank linings, floor coatings, and outdoor structures needing combined chemical and weathering protection.
Common Applications
Where Plural Component Coating Are Used
These systems are built for the toughest containment and lining jobs – environments where conventional coatings would fail.
Tank Linings
Internal Pipe Coatings
Protecting the inside of pipes from corrosion, chemical attack, and flow erosion with thick, uniform internal linings.
Frack Tanks
Secondary Containment
Seamless containment coatings for berms, pits, and spill areas where chemical resistance and impermeability are non-negotiable.
Applied with Graco Two-Component Equipment
Why Plural Component
Key Advantages
Extreme Thickness
Apply very high mil builds in a single pass — far exceeding what conventional spray or brush coatings can achieve.
Fast Cure
Materials reach handling strength in minutes, not hours — dramatically reducing downtime and turnaround on lined equipment.
Chemical Resistant
100% solids systems form dense, impermeable barriers against acids, caustics, solvents, and hydrocarbon exposure.
Seamless Barrier
No joints, seams, or weak points — the coating forms a monolithic, continuous lining across the entire surface.
