Adhesives, Sealants & Industrial Bonding calculator
Two-Part Mix Ratio Calculator
Correct mix ratio is critical for two-part epoxies, urethanes, silicones, and acrylic adhesives. This calculator compares Part A and Part B quantities and applies the required conversion factor so technicians can check weight-based or volume-based mixing before dispensing.
What this calculator does
- Calculate the mix ratio between resin and hardener after applying the required supplier conversion factor.
- a bonding technician needs to verify Part A to Part B ratio before a mixed adhesive batch is released
- Returns the calculated resin-to-hardener mix ratio after conversion.
Formula used
- Raw mix ratio = Part A resin amount ÷ Part B hardener amount
- Adjusted mix ratio = raw mix ratio × supplier conversion factor
Inputs explained
- Part A resin amount: undefined
- Part B hardener amount: undefined
- Supplier conversion factor: undefined
How to use the result
- Use it before hand mixing, pressure-pot mixing, meter-mix setup, or batch record review.
- It does not confirm complete mixing, degassing, pot life, or cure; it only checks proportioning from the entered amounts.
Common questions
- What information do I need for two-part mix ratio? You need Part A amount, Part B amount, and whether the supplier ratio is by weight or volume with any density conversion factor.
- Which units should I use for two-part mix ratio? Use the units shown beside each field and convert plant data before entering it. Keep length, area, mass, volume, time, and currency units consistent with the dispense method or supplier data sheet.
- What does the two-part mix ratio result tell me? It shows the adjusted Part A to Part B ratio so you can compare it with the technical data sheet.
- When is this two-part mix ratio estimate only directional? Use it to catch proportioning mistakes before parts are bonded, potted, or sealed.
