Coatings, Inks & Specialty Chemical Production calculator
Resin Usage Calculator
Separate supplied resin usage from its nonvolatile solids contribution. Enter the charge rate, active charging time, purchase price, and supplier weight solids percentage.
What this calculator does
- Calculate supplied resin usage, nonvolatile solids contribution, and resin purchase cost.
Formula used
- Supplied resin = charge rate × active charge time
- Nonvolatile mass = supplied resin × weight solids ÷ 100
- Resin purchase cost = supplied resin × unit cost
Inputs explained
- Supplied Resin Charge Rate: Measured mass flow of resin as supplied.
- Active Resin Charge Time: Charge log excluding later cook or mixing time.
- Supplied Resin Unit Cost: Invoice price per pound of supplied resin.
- Resin Weight Solids: Supplier nonvolatile weight percentage for the resin grade.
How to use the result
- Best suited to nonvolatile solids reconciliation, resin purchase forecasting.
- Nonvolatile mass is not a prediction of retained or cured film mass.
Current U.S. benchmarks
- Industrial electricity averages 9.77 cents per kWh across the U.S. (EIA, Jul 2026), up 4.7% from a year earlier. Energy-intensive steps carry this directly into unit cost.
- The producer price index for industrial chemicals stands at 336.006 (BLS, Aug 2026), up 13.3% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- The U.S. has 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).
Common questions
- Is the supplied resin mass entirely nonvolatile? Only for a resin specified as 100% weight solids. The result follows the supplier nonvolatile measurement and can include nonvolatile additives alongside polymer.
- Can I use volume solids from a coating datasheet? No. This mass calculation requires weight solids for the resin being charged, not the finished coating volume solids.
- Does the cook time belong in charge time? Only the time during which resin actually flows belongs here. Later heating or mixing does not consume resin through the charge meter.
- Which price should I enter for a resin emulsion? Enter the invoice price per pound of the supplied emulsion. Do not enter a price per dry pound unless you first convert it.
