PAT is an authorized REPI formulator. We produce custom-matched colors in-house using REPI pigment systems, backed by decades of colorant application expertise.
Founded in 1973 in Uggiate-Trevano, Italy, REPI is one of the world's leading producers of liquid colorants and additives for polyurethane, thermoplastic, and epoxy systems. REPI has facilities in Italy, the US, Germany, the UK, Russia, and Thailand, and local distribution partners on every continent.
Their colorants are engineered for specific chemistries, carrier vehicle compatibility, heat stability, and UV performance. RoHS and REACH compliance is standard across the line.
The full REPI range runs wider than polyurethane color: liquid pigment dispersions including carbon black, polyurethane colorants and performance additives, the REMAP range of colorants for thermoplastics, polymeric colors for PET, HDPE, PP, PVC, ABS, PC, PMMA and recycled polymers, packaging additives, and dosing equipment. If you use a part of the range we do not stock, ask and we will source it through the relationship.
PAT holds authorized formulator status with REPI. We take REPI pigment systems and produce custom colors against customer specifications, in-house, with the manufacturer's technical support.
Our Maine facility produces custom liquid color dispersions matched to PANTONE, RAL, Federal Standard, and physical sample references, then ships them in customized package sizes with batch-to-batch consistency. When you order a color from PAT, you're getting a product made in the United States.
Mass coloration and third-stream dosing for PU, TPU, and PVC soles, uppers, and components. The shades already matched for this lane are on the shade reference.
Colorants engineered for foam chemistry, compatible with polyol and isocyanate systems. The carrier logic and dosing are on liquid color for polyurethane foam.
Dispersions suitable for cast urethane systems, with formulations matched to specific resin and hardener chemistries. The carrier logic and dosing are on liquid color for cast urethane.
Colorants for poured and broadcast PU flooring, including broadcast systems requiring heat and UV stability. The carrier question for these systems is on liquid color for epoxy and polyurea.
Liquid colorants for TPU processing: third-stream addition at the press, or pre-mixed dispersions for batch production.
Colorants for rigid foam, structural PU, and reaction injection molding (RIM) applications.
The color is blended here, so the pages below are organized by the system it goes into. Each carries the carrier logic for its lane, the addition range and the documentation.
| System | Carrier | Where it fits |
|---|---|---|
| Plastisol | Phthalate-free plasticizer | Dip molding, rotocast, flexible PVC and coated fabric |
| Cast urethane | Plasticizer or polyether polyol | Wheels, rollers, screens, seals and wear parts |
| Polyurethane foam | Polyether polyol, polyol side | Flexible and integral-skin foam |
| Spray polyurethane | Polyether polyol, resin side | Bedliners, linings, traffic and utility components |
| TPU and thermoplastic | Solid carrier resin, pelletized | Extrusion, injection molding and compounding |
| Epoxy and polyurea | Selected for the side it meters into | Flooring, casting and gelcoat |
Every PANTONE and RAL code matched here is listed on the shade reference, and the six systems sit together on the liquid color index.
