Excellent Clarity and Durability
#3500 Clear Urethane Casting Resin is perfectly water clear and won’t yellow with UV exposure like an epoxy would. Also, it won’t discolor in high humidity environments. This room temperature cure, two-part casting resin is self leveling and can be poured to create exceptionally rigid, durable, and impact resistant parts in applications that previously used acrylic or polycarbonate.
It is more resilient than clear polyester casting resins, and can be used to create quieter, more durable tabletops than clear epoxy resins. Typical applications include: lenses, clear reproduction parts, decorative pieces, prototype models, tabletops, and encapsulations. This resin can pour castings as shallow as 1/4″ up to 3″ deep at a time.
When mixed thoroughly, pour the clear urethane slowly to aid the release of air bubbles. It may be necessary to place the mixed resin in a degassing chamber to ensure all air is released to achieve a perfect casting. When using Clear Urethane Casting Resin, avoid water and all types of moisture contamination. Avoid direct contact with wood. Do not use any urethane kit with PVA Release Film, and do not mix with wooden mixing sticks. #2333 Plastic Paint Stirrers for Urethanes are recommended. To ensure a proper release from a mold, use at least four layers of #4121 Non-Silicone High Temp Paste Wax.
If using as a tabletop coating, it is advisable to clean the tabletop surface with alcohol and dry with a heat gun. This will ensure the surface is moisture free. Light heat can also be added to aide in outgassing during the cure cycle. Do not over heat. As a tabletop resin, our #3500 Clear Urethane is quieter than epoxy resins, and will not crack.
