Ultratint™ – Colorants for Polyurethanes
Deep Color. Zero Solvent. Total Compatibility.
Overview
Ultratint™ is Soujanya’s line of solvent‑free liquid colorants engineered for demanding polyurethane (PU) applications. Whether for PU foams where vivid, deeply pigmented color is essential, or for solvent‑free PU floor coatings, Ultratint delivers exceptional color strength, stability, and non‑migrating performance.
Ultratint colorants become part of the PU polymer matrix, preventing extraction or migration, and enabling deep, bright shades, even at lower usage levels. They are designed to perform without disrupting resin behavior, fungible across a wide variety of PU systems.
Key Features & Benefits
100% solids, solvent‑free liquid colorants
No carrier solvents; clean, safer, compliant for solvent‑restricted or regulated environments.
Matrix‑integrated colorants (non‑migrating, non‑extractable)
Once cured, color remains locked in—no bleeding, staining, or discoloration, even in harsh or wet environments.
High color strength (3×‑5× vs traditional pigments)
Enables deeper coloration with less colorant, reducing cost‑in‑use and lowering loading of pigment solids.
Low impact on resin chemistry
Effective color action without harming cure, catalysis, foam rise or causing defects like scorch or streaks.
Blendable primary color base for unlimited shades
Less inventory needed; primary hues can mix to custom shades rather than having large pigment‑paste SKUs.
Exceptional shade quality: reduced scorch & streaks
Smooth, homogeneous dispersion; even coloration even under tough process variations.
Durable performance under stress
Excellent UV/weather resistance, abrasion‑resistance in floors; fade protection especially in exterior applications.
Technical Excellence
Homogeneous liquid that becomes part of polymer matrix: Once Ultratint cures inside the PU, color is locked in mechanically and chemically—helping prevent migration or extraction.
Strength‑to‑Loading efficiency: Because Ultratint gives 3×‑5× color strength vs many pigment pastes, you can use lower volumes with same or improved visual output.
Resin‑friendly behavior: Designed so that tinting doesn’t impede foam rise, cure speed, or interfere with resin crosslinking.
Reduced defects: Special attention to dispersion, pigment properties, and compatibility to avoid streaks, scorch, or uneven color patches.
Broad application compatibility: For flexible and rigid PU foams, solvent‑free floor coatings, and PU coatings for interior / exterior applications.
Applications
PU Foam Coloring — furniture, bedding, automotive interiors, insulation foams.
Solvent‑Free PU Floor Coatings — durable, wear resistant floors in industrial, commercial, or residential settings.
Architectural PU Coatings — doors, trims, exterior PU finishes where solvent‑free systems are mandated or preferred.
OEM PU Color Applications — molded parts, vehicle interiors, applications needing high color and compatibility.
