About P.A.T. Products

P.A.T. Products blends liquid pigment dispersions at its own plant in Hermon, Maine. The product is a match: you send the target and the system it has to work in, and we build a dispersion that hits the target in that system.

The pages below are organized by system rather than by shade, because the system is the decision. A dispersion that is right for plastisol is wrong for a spray polyurethane, and a carrier chosen without the chemistry in front of it is the most common reason a color trial disappoints. Tell us what you are coloring and the carrier follows from it.

Color here almost never means decoration. It means a durometer a maintenance crew can read across a rack of wheels, a regulatory code on a highway delineator or a utility marker, a federal standard on a defense part, a wear layer that changes color when it is spent, or a shade that identifies a genuine part against a copy. That is a harder job than looking good, and it is what these dispersions are built for.

The tolerance is ΔE 1.0 or better, measured CIELAB against the approved standard on a spectrophotometer at D65 and a 10 degree observer, with the reading on the certificate of analysis for every batch. Most matches come back in about a week. Samples are free and there is no minimum to try one.

Pigments and color

Liquid color for cast urethane

Pigment dispersion in a phthalate-free plasticizer or a polyether polyol carrier. Low-viscosity dispersions that meter into a cast PU system and develop full color before the mix gels. Plasticizer or polyol carrier, matched to your resin and hardness.

Liquid color for epoxy and polyurea

Pigment dispersion in a carrier selected for the resin or amine side of the system. The carrier question decides this one. Tell us whether the color goes in the resin side or the amine side and what the system has to do, and we will match into it.

Liquid color for plastisol

Pigment dispersion in a phthalate-free plasticizer carrier. The system we match most. A plasticizer-carried dispersion belongs in a plastisol, because the carrier is already an ingredient of the compound.

View product

Liquid color for polyurethane foam

Pigment dispersion in a polyether polyol carrier, metered on the polyol side. Flexible and integral-skin foam, colored on the polyol side. The carrier goes into the reaction, which is what a foam needs.

View product

Liquid color for spray polyurethane

Pigment dispersion in a polyether polyol carrier. Spray polyurethane takes a polyol carrier. Every spray match run here has, and a plasticizer-carried dispersion is the wrong answer to this system.

TPU and thermoplastic masterbatch

Pigment concentrate on a solid carrier resin, pelletized. The solid-carrier format, for a process that melts. Pelletized concentrate that meters with the natural resin at the throat and disperses in the melt.
