Coatings, Inks & Specialty Chemical Production worked example

Resin Usage with resin or binder charge rate of 55 lb / hr: a worked example in coatings, inks & specialty chemical production

This worked example runs the resin usage numbers for a tougher week than the baseline: resin or binder charge rate of 55 lb / hr instead of the typical 110 lb / hr. Estimate resin or binder consumption and cost from resin addition rate, batch time, and resin unit cost.

The inputs for this scenario

  • Resin or binder charge rate: 55 lb / hr (the input this scenario stresses; the baseline uses 110)
  • Resin charge or cook time: 4 hr (held at the documented default)
  • Resin cost per pound: 3.85 $ / lb (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Resin Usage consumed = resin or binder addition rate × resin addition time.
  • resin usage consumed works out to 220 lb at these inputs, and this is the headline figure for the scenario.
  • resin usage cost works out to 847 $ at these inputs.
  • resin addition time works out to 4 hr at these inputs.
  • resin cost per pound works out to 3.85 $ / unit at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where resin or binder charge rate sits at 110 lb / hr and the headline result is 440 lb, this scenario comes in 50% below the baseline at 220 lb.
  • Use it when planning a resin charge, drawing down binder inventory, or costing the resin backbone of a coating or ink formula. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
