WebMar 12, 2024 · Casting, also called deep-pour epoxy, has low viscosity and longer curing times. It is mixed in a 2:1 ratio of liquid resin and hardener. it is ideally used for fully embedding objects in the resin, but is also useful in filling gaps and holes in various materials and increasing their strength and stability. Jewellery, electrical insulation and ... WebShrinkage. Shrinkage is the reduction in volume during cure. Excessive shrinkage will cause internal stresses and serious degradation in the performance of the solidified epoxy. Epoxy systems containing fillers shrink less than unfilled epoxies. As a rule, the higher the filler content the lower the shrinkage.
