Craft Resin technical specifications

Every controlled technical value for Craft Resin lives on this page. If a figure appears anywhere else and disagrees with this page, this page is correct.

Always measure by VOLUME, not by weight. Equal weights are not equal volumes. Measuring by weight is the single most common cause of a kit that appears to be short on hardener, and of a pour that never fully hardens.

Room temperature by batch size — Deep Pour only

Deep Pour cures by an exothermic reaction and the larger the mix, the more heat it holds. Match the room to the batch:

Batch	Room temperature
1–5 kg	22–25°C
5–10 kg	20–23°C
10–20 kg	18–21°C
over 20 kg	below 18°C

Never use a heat gun or torch on a Deep Pour. Adding external heat to a deep reactive mass increases the risk of overheating, cracking and yellowing. Torching is for thin coating layers only.

UV Resin

Single component — there is no mixing ratio. Cures in 60–120 seconds under a suitable UV lamp, depending on lamp power and layer thickness. Cured hardness 86 Shore D.

Things that are often confused

Working time is not curing time. Working time is how long you can pour and manipulate the mix. Curing takes hours after the resin stops being workable.

21 days is not a cure time. All three resins are hard and usable long before that. Over roughly 21 days the piece continues to develop its full mechanical strength and scratch resistance. It is not a condition for the heat rating.

Heat resistance is a material property, not service advice. Do not place hot cookware, hot pans or boiling liquids on a resin surface. A warm mug is normally fine; a pan from the hob is not. Use a trivet.

Bigger mixes give you less time, not more. Working time falls as the mixed volume rises.

Cold and damp both matter. Below 15°C, warm Part A to 30°C before mixing. Above the humidity limits above, the cured surface can cloud — do not room-cure on very humid days.
