Quick Answer
KS Resin KS Resin 500 Deep Pour Epoxy mix ratio: 3:1 by volume, 3:0.92 by weight
Max pour depth: 2.0" · Full cure: 72h · Ideal temp: 75°F · Price: $80–$180/gal
⚠️ Exothermic Risk — The weight ratio (3:0.92) is NOT 1:1. Resin and hardener have different densities. Using a 1:1 scale ratio will result in incorrect curing. Always mix by weight using the ratio above.
High-performance deep pour casting epoxy with ultra-low viscosity for detailed castings and river tables. Slow cure minimizes exothermic heat for safe deep pours. Crystal clarity with excellent UV stability for long-lasting results.
