Viscosity control is an important part of many carpet backing formulations.

SBR latex is usually combined with other formulation components, including fillers and thickeners, to achieve the required coating viscosity.

Why Is Viscosity Important?

The formulation viscosity can affect:

  • Mixing
  • Pumping
  • Coating
  • Penetration
  • Application weight
  • Surface appearance

The appropriate viscosity depends on the coating method and production equipment.

SBR Latex and Thickener Compatibility

When changing SBR latex, the thickener system may also need to be reviewed.

Factors that can influence the final viscosity include:

  • SBR latex solids
  • SBR viscosity
  • pH
  • Thickener type
  • Thickener dosage
  • Filler loading
  • Mixing conditions

A new SBR grade should therefore be evaluated using the actual thickener and filler system used by the carpet manufacturer.

RUICO supplies SBR latex for carpet backing applications and can support customers during formulation trials.
