Buying Guide

Resin type and formulation

Choose epoxies formulated for casting that advertise self-leveling, crystal-clear finishes and compatibility with silicone molds to avoid tacky or cloudy cures

UV resistance matters

Select UV-resistant formulas if parts will be exposed to sunlight or UV light to reduce yellowing and extend optical clarity over time

Working time and cure profile

Match pot life and cure speed to your workflow—longer working time helps with larger pours, while faster cures speed turnover for small-batch runs

Mixing system and measuring

Prefer kits with clear resin-to-hardener ratios or included pumps to ensure accurate metering; incorrect ratios cause soft or uncured spots

Finish & post-processing

For glossy, bubble-free parts look for self-leveling epoxies and follow recommended degassing or surface-tension practices; hardened surfaces should be sandable and polishable if needed
