Why am I Left With More Resin in One Bottle Than the Other once Finished a Resin Kit

Often when artists are finished their resin kits, they find they have more of one part than the other (this happens in all brands). This can occur for a variety of reasons.

It is very common to have more of one part A (resin), or B (hardener) left than the other.

Sometimes it can be from being ever so slightly off in our measuring.

But the extra liquid in one container, might be also due in part, to one container having a bit extra added from manufacturer.

Some manufacturers fill bottles by weight, however some manufactures also add a bit more (so people actually receive more volume in bottles than stated). This is also a reason you should never dump both full bottles into mix cup, assuming it will be correct amount stated on bottles.

Always measure by a manufacturer’s recommended suggestion.

With some of the medium and thicker viscosity epoxies, Part A is heavier than Part B, & those resins typically are developed to be measured 1:1 ratio by volume (measure in cups). So these types of resins are not measured by weight (unless manufacturer provides you the disparity measurement factor).

There are some resins, where both Parts A & B weigh the same, that a manufacturer may suggest that brand can be measured by weight (scale), or volume (graduated measuring cups).

If it is a 2:1 ratio epoxy, just remember to use double amount of Part A Resin (the bigger bottle), to the amount used from Part B Hardener (the smaller bottle).

Some people find it frustrating, but many realize it is just a common occurrence.

Some artists say they pour that extra into their newer bottle of same product.

***If you would like to request a half kit be added to website (to make available for purchase), we can do that. If so, please use website “contact us“, to advise which resin type, which kit size, & which part (a or b), then I will add to site as per request, and let you know when it's online ready for your purchase. If it's a 2 bottle kit, the price will be half of a full kit. If it's a 3 bottle kit, the price will be 1/3 of a full kit.

Note: The partial kit request needs to be done via website “contact us”, so we can confirm inventory of said item first, & then we can then adjust inventory of full kits accordingly at that time as well.
