We highly recommend weighing out HXTAL.

Part A and Part B has different densities and your ratio will be off when mixed by volume instead of by weight. For very small mixtures, being off will not significantly affect HXTAL's ability to cure, but the larger the amounts of mixed epoxy, the greater the difference in ratio and the more likelihood bonding problems will occur. We offer a number of affordable scales that can be used to accurately weight out HXTAL for bonding.
