Great Planes Slow-Cure 30 minute epoxy forms the strongest bonds, is water resistant and more heat resistant than the quick cure 5 minute epoxy. Bonded parts can be safely handled after 1 hour and full strength is attained after 24 hours. To best take advantage of it’s strength use it to fillet already formed joints. It can be mixed with microbaloons to form a putty-like consistency which is ideal for the task.

All Great Planes epoxies are mixed in 50:50 ratios. Squeeze out equal length beads of the desired amount of epoxy, then mix together thoroughly with an ice-block stick or scrap piece of material. In cold weather, epoxy takes longer to cure and becomes more difficult to get out of the bottle, especially if it’s less than 1/2 full. The epoxies can be heated by standing the bottles in a cup of hot water so that they flow easier. The heating process, with the caps off, also releases any moisture that can be absorbed by epoxies. Their shelf life, therefore, is virtually unlimited.
