Adhesives, Sealants & Industrial Bonding calculator

UV Adhesive Cure Dose Calculator

Calculate UV energy delivered at the adhesive and check two qualified process limits. Enter measured bond-line irradiance, exposure time, required dose and minimum irradiance.

What this calculator does

  • Calculate delivered bond-line UV dose and compare it with your validated dose and minimum irradiance requirements.

Formula used

  • Delivered dose = bond-line irradiance × exposure seconds
  • Dose margin = delivered dose − required dose
  • Required exposure = required dose ÷ bond-line irradiance
  • Irradiance margin = measured irradiance − minimum irradiance

Inputs explained

  • Measured Bond-Line Irradiance: Radiometer reading at the bond through the actual optical path.
  • Exposure Time: Recorded illumination duration for the qualified production cycle.
  • Validated Required Dose: Minimum dose established for this adhesive and optical setup.
  • Validated Minimum Irradiance: Minimum acceptable bond-line intensity from your qualified process.

How to use the result

  • Best suited to qualified UV recipe Checks, lamp output drift checks.
  • Dose alone does not prove conversion, cure depth or bond strength. Use matching radiometer wavelength response and the qualified lamp spectrum.

Current U.S. benchmarks

  • 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 11,391 plastics and rubber products establishments employing about 815,988 workers (Census County Business Patterns, 2023).

Common questions

  • Why is there no transmission percentage? The measured bond-line irradiance already includes optical losses. Applying another transmission factor would count those losses twice.
  • Can longer exposure replace insufficient irradiance? Only within a separately qualified process window. This calculator flags a failed minimum irradiance even if accumulated dose reaches the target.
  • Does production yield change the dose? No. Yield counts accepted parts; it does not change the energy delivered to a particular bond.
  • What if irradiance changes during exposure? Use a radiometer that integrates energy over the actual exposure. Multiplying a single peak reading by time can overstate delivered dose.
