Product Description
PC-3™
Smooth-On PC-3™ Laboratory Table Top Cement is a two-component, black epoxy resin compound designed to join, bond and caulk sections of laboratory counters and tables. This epoxy resin cement is heavily filled and will adhere to vertical surfaces without sagging. It cures at room temperature with extremely low shrinkage.
TASK™ 14
TASK™ 14 is a fast setting two-component urethane that cures quickly to black semi-rigid plastic. TASK™ 14 offers a longer pot life (10 minutes) and demold time of 45 minutes.
With a Shore value of 50D, these semi-rigid plastics are used for a variety of industrial applications including fast mold making, fast model duplication, prototyping, durable miniatures, black props and special effects, or making parts that are impact resistant. Fully cured castings are tough, durable and chemical resistant.
For Best Results… Do not cast TASK™ 14 into platinum cure (addition cure) silicone molds.
