Color-Coded Systems
Pantone-Style Formulation Cards for Specifiers
Each family carries a distinct swatch that appears on pails, literature, and TDS downloads—so procurement, applicators, and inspectors stay aligned.
Epoxy & Polyurethane
High-build epoxies, zinc-rich primers, and UV-stable polyurethane finishes engineered for severe-duty corrosion defense.
Acrylic & Hybrid Finishes
Fast-dry, odor-controlled formulations that keep OEM and commercial lines running while meeting strict air permits.
Assembly & Structural
Gap-filling epoxies and hybrids tuned for high-shear joints, dissimilar materials, and fast takt times.
Sealants & Fillers
Elastomeric and fire-retardant systems that maintain joint movement, aesthetics, and code compliance.
Surface Prep & Support
Cleaners, conversion coatings, and accessory products that lock in adhesion, cure, and lifecycle performance.
