Thermoset Pigment Dispersions

Optimizing pigment concentration

Get set to experience the difference

Thermosets come in various forms and generally start off in a liquid state for coatings resins and powder for plastics applications. In order to ‘set’ the resin the molecules need to be cross-linked through a catalytic chemical reaction or heated to create strong bonds with each other. Once the reaction is completed the resin can no longer return to its original form. In other words, unlike thermoplastics, it cannot be melted, recycled, and reused repeatedly.

The many thermoset polymers and plastic types include epoxy, polyurethane, silicone, PVC, polyester, each having their own unique properties, benefits and shortcomings, and end-uses. Just as with paints and coatings, thermoset products do not miraculously start out coloured! They rely on pigment dispersions to give them character, enhance their UV protection, infrared reflectivity, increase structural integrity, and a host of other benefits.

Our thermoset pigment dispersions and colorants are designed to provide our customers with outstanding value by optimizing pigment concentration at a rheology that makes sense. We always consider your specific needs and requirements to tailor the finished product to provide the ideal properties for each situation.

Our various offerings are all 100% solids dispersions and include the following:

Plasticizer Dispersions:

Pigment plasticizers dispersions generally have universal application in areas such as urethane foams and integral skin, RIM, coatings, castable urethanes and other elastomers, adhesives, caulks, flexible PVC such as PVC coated fabric, slush molding, dip molding, roto-molding, calenderer sheets and films, flooring, wire and cable.

  • Non-Phthalate: DINCH , a compliant and phthalate free plasticizer, is a close relative to DINP and can generally be used in equivalent circumstances.
  • Phthalate Compliant: DOTP, much like its cousin above, is fully compliant as a phthalate-free alternative plasticizer. Its universal application is similar to that of DINCH.
  • Benzoate Ester: A separate and distinct plasticizer chemistry, similarly phthalate free.
  • ESO: A bio-based, non-phthalate plasticizer derived from soya oil.

Polyurethane Dispersions

The Polyurethane vehicle used in this line of pigment dispersions is PPG-1000. It is a polyether polyol which is 1,000-molecular-weight polypropylene glycol. Pigment dispersions using PPG1000 are typically used in a broad range of urethane foams as well as other applications including coatings, solvent and water-based adhesives, caulks, sealants, elastomers, potting compounds, and inks.

Castor Oil (Urethane Grade) is a renewable, sustainable, and environmentally friendly, low moisture castor oil is a low-cost alternative to polyol for many urethane formulations. Used extensively in urethane adhesives and sealants, urethane flooring and coatings, and urethane foam applications, it is found to offer both enhanced performance properties and conventional urethane curatives.

Epoxy Dispersions

These pourable dispersions are designed to work universally in several epoxy resin pigment systems including industrial and maintenance coatings, thermoset casting and composites, pultrusion, and adhesives. Color tint options include standard single pigment dispersions as well as blended color packs in ready-to-use 500 ml containers.

100% solids epoxy color pigment dispersions are notoriously difficult to handle as a result of the inherently high room temperature viscosity of the epoxy resin. Our formulations seek to overcome this problem by using a unique and proprietary combination of low viscosity resin, functional diluents, dispersants, and additives that allow for comparably higher pigment loading in an easy-to-handle viscosity.

Our epoxy color additive and epoxy pigment paste are essential to our epoxy floor coating colors making us a strong epoxy pigments supplier.
