"Crystal clear resin" typically refers to a type of epoxy resin or polyester resin that cures to a transparent, glass-like finish. It is widely used in art, jewelry making, woodworking, crafts, and even industrial applications due to its clarity, durability, and aesthetic appeal.
Types of Crystal Clear Resin
Epoxy Resin (Most common)
Two-part system: Resin + Hardener
Cures at room temperature
Longer working time (pot life)
Excellent clarity and UV resistance (varies by brand)
Self-leveling and bubble release
Ideal for: Art, jewelry, river tables, coatings
Polyester Resin
Single-part with catalyst (MEKP)
Cures faster than epoxy
Stronger smell, more toxic fumes
Can be brittle and yellows over time
Ideal for: Molds, castings, industrial applications
Polyurethane Resin
Cures very fast
Good clarity but sensitive to moisture
Short pot life
Ideal for: Small castings, prototypes
Properties of Crystal Clear Epoxy Resin
Property Description
Transparency Water-clear, glass-like finish
UV Resistance Some brands include UV inhibitors (prevents yellowing)
Working Time 20–60 minutes (depends on formula)
Curing Time 12–72 hours (varies by thickness and temperature)
Mix Ratio Commonly 1:1 or 2:1 (resin to hardener by volume or weight)
Viscosity Ranges from low (for deep pour) to high (for coating)
Durability Hard, glossy surface once cured
Heat Resistance Moderate; can be increased with heat-resistant formulas
Applications
Art: Pouring, coating, and resin painting
Jewelry Making: Molds, pendants, cabochons
Woodworking: River tables, bar tops, encapsulations
Crafts: Coasters, doming, keychains, figurines
Decorative Castings: Flowers, insects, memorabilia
Wear gloves, safety goggles, and mask
Avoid skin contact
Store in a cool, dry place
Dispose of waste properly (hardened resin is safe, but liquid components are not)
