Summary:Aug 29,2026

Coating weight is an important parameter in carpet backing production.

The required coating weight depends on the carpet construction, backing system, bonding requirements and production process.

SBR latex characteristics can influence the formulation used to achieve the target coating weight.

What Should Technical Teams Consider?

When adjusting coating weight, manufacturers may review:

  • SBR latex solids
  • Latex dosage
  • Filler loading
  • Viscosity
  • Thickener dosage
  • Coating equipment
  • Line speed
  • Drying conditions

A change in SBR solids content can change the wet formulation dosage required to achieve a specific dry polymer level.

Balancing Coating Weight and Cost

For purchasing and technical teams, coating weight can also be connected with raw material cost.

A practical evaluation can compare:

Wet coating weight → Dry polymer content → SBR consumption → Cost per m²

This provides a more direct connection between formulation design and purchasing cost.
