Product Description
EZ-Mix™ 40
EZ~MIX™ 40 is a brushable polyurethane rubber mold compound that mixes and applies easily. Two liquids (Part A and Part B) are measured and combined in equal amounts by volume (no scale is necessary). After a few minutes of mixing, EZ~MIX™ 40 is ready to be applied to a vertical surface with a brush. After a suitable thickness is attained (multiple layers), EZ~MIX™ 40 cures overnight with negligible shrinkage to a flexible, durable mold rubber. Following the application of a support shell, a rubber mold made with EZ~MIX™ 40 is suitable for casting a variety of materials including wax, gypsum, urethane/epoxy resins, concrete, cement, etc.
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.
