I only ever create my products with Ecopoxy bio resin. Ecopoxy- UVpoxy resin is a more expensive resin which is why my prices are high but the quality is well worth it: UVPoxy is a professional quality, high-performance epoxy system that’s UV stable and produces a high build crystal clear finish. It is UV RESISTANT to prevent yellowing over time.Developed for commercial-grade applications, UVPoxy resists yellowing, fading, and cracking. This epoxy is extremely durable, capable of withstanding heavy use in high-traffic venues
