General-purpose liquid color for thermoplastics

SPECTRAFLO® liquid colors are concentrated, low-viscosity liquids comprised of the highest-quality pigments dispersed in proprietary vehicles, compatible with most thermoplastics and engineering resins. The vehicles are specially designed to eliminate plate-out and exudation, and will not affect printability.

High pigment loadings up to 80 percent, result in significant cost reduction. Letdown ratios of 100:1 to 200:1 are typical for opaque colors, while letdowns of over 1,000:1 can be achieved for transparent colors.

Types of pigments
  • Heat stable
  • Light stable
  • Organic
  • Inorganic
  • Fluorescent
  • Pearlescent
  • Heavy metal free
  • FD&C compliant
  • FDA compliant
  • Chemical resistant
  • Special effects

Through mechanical processing, pigment agglomerates are broken down to wet-out individual particles and maximize the tinctorial strength of the pigment.

With loadings up to 80 percent, these concentrated colors enable you to dramatically decrease coloring costs, while increasing color uniformity and minimizing adverse effects on physical properties.

Standard colors

A range of standard single-pigment color dispersions is in stock for immediate shipment, while an entire spectrum of other single-pigment dispersions and custom blends are available on short notice.

Ferro is dedicated to providing value-added products and services that meet your requirements for color control, ease of processing and maximum cost effectiveness.

Precision color matching

Ferro technicians combine their talents with state-of-the-art computer analyzing equipment to offer you an unsurpassed color-matching service. Spectrophotometry minimizes metamerism, speeds color matching, promotes consistent quality and helps identify the pigment/dye combination that produces any given color for the lowest cost. Our color library consists of over 4,000 custom-matched colors.

Ferro can match your color chip, or refer to complete files of OSHA, Munsel, Federal Standard 595 Series or Pantone® matching systems and match according to your reference number. All orders are matched to Ferro standards or the retain of your approved custom color, ensuring identical color reproduction from order to order.

Equally important is that every Ferro color match takes into consideration all of your color requirements including heat and light stability, FDA compliance, chemical resistance, etc. Ferro can even incorporate a range of surface-effect additives into your liquid colorant to create a multi-functional package, enabling you to monitor all of your additives by monitoring only your color.

Liquid color pump

A reliable, low-cost, peristaltic metering pump injects liquid color directly above the plasticating screw of injection molding and extrusion machines.

Only the colorant feed tube comes in contact with peristaltic pump rollers, allowing 10-minute color changeovers.

Natural resin in the hopper never requires emptying, eliminating the shutdown time required to dry precolored resin and colored compounds and the space required to store them.
