Deep pour epoxy resin is a special type of casting resin designed for thick applications, allowing single pours of up to 2-6 inches (5-15 cm) or more depending on the formulation, without overheating or excessive bubbles.
What Is Deep Pour Epoxy Resin?
Deep pour epoxy resin is formulated for large volume projects like river tables, art castings, and encapsulation work, where regular tabletop epoxies would overheat or cure too quickly if poured in thick layers. These products often have low viscosity for easier flow, excellent self-degassing to minimize bubbles, and extended working times to manage thicker pours.
Common Uses
- River tables and large slab wood projects
- Thick artistic molds and sculptures
- Decorative blocks with embedded objects (flowers, stones, photos)
- Countertops and deeper castings requiring high clarity
Typical Properties
- Pouring Depth: Most deep pour epoxies allow 2”–6” (about 5–15 cm) in a single pour, though some high-end formulations can go deeper under controlled conditions.
- Clarity & UV Resistance: Designed for ultra-clear results and maximum UV protection to resist yellowing.
- Slow Curing: Extended working and curing times, sometimes requiring up to several days for full cure in thick layers.
- Low Viscosity and Self-Degassing: Flows easily into deep molds and releases bubbles efficiently.
- Hardness: Forms durable and strong final castings suitable for furniture and art.
Key Considerations
- Pouring too much at once or at high temperatures can cause overheating ("exotherm"), which risks cracking and yellowing.
- Always follow manufacturer guidelines for max recommended pour depth, temperature, and mixing ratio for best results.
- For very large projects, deep pour resin is usually poured in multiple layers.
