PERBOND
Bond it right — epoxy ratios, joint design, cure timing, and the adhesive calculators every workshop needs.
From estimating how much adhesive to buy and mixing two-part epoxy on-ratio to sizing a joint, adjusting cure time for temperature, and stretching a cartridge across a run, PerBond pairs free hands-on bonding calculators with practical guides and an illustrated museum. Prep well, bond once.
Adhesive & Bonding Calculators
Free tools for every bond — adhesive coverage calculator, epoxy mix ratio calculator, bond strength calculator, cure time calculator, coverage per cartridge, and lap joint designer.
Adhesive Coverage Calculator
Work out how much adhesive a job needs, from a bond area and glue-line thickness or a bead diameter and length, as a volume and approximate mass.
Epoxy Mix Ratio Calculator
Split a two-part epoxy batch into Part A and Part B by weight or volume at any ratio, with a warning when a big batch will shorten pot life.
Bond Strength Calculator
Estimate the load a lap-shear joint can carry from its area and the adhesive's shear strength, or the minimum area for a target load.
Cure Time Calculator
Adjust a base cure time for temperature, using the rule that cure roughly halves for every 10 °C rise and doubles for every 10 °C drop.
Coverage per Cartridge Calculator
Turn a cartridge or container volume into linear metres of bead at a chosen diameter, or the area it covers at a chosen spread thickness.
Lap Joint Designer
Size the overlap length a single-lap joint needs to carry a required load at a given adhesive shear strength and joint width.
The Museum
Wander an illustrated museum built entirely from Wikipedia and Wikimedia Commons — browse its collections, each in its own gallery, purely for the pleasure of looking and learning.

Guides on choosing the right adhesive, prepping surfaces, mixing and curing epoxy, and designing stronger joints — practical reading to pair with the calculators above.
