Product Description
Ecoflex™ 5
Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and de-airing. Dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.
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.

Clear Flex™ 50
Clear Flex™ 50 is a water white clear urethane liquid rubber compounds designed for applications that require absolute clarity and resistance to sunlight. Low viscosity ensures easy mixing and pouring. Clear Flex™ 50 will cure at room temperature with negligible shrinkage.
CAUTION: NOT FOR HOME USE. THIS PRODUCT IS FOR INDUSTRIAL USE ONLY. With adequate local exhaust ventilation, respiratory protection is not normally required when using this product. Where risk assessment shows air-purifying respirators are appropriate, follow OSHA respirator regulations and European Standards EN 141, 143 and 371. Protective clothing (gloves and long sleeves) is required to minimize the risk of dermal sensitization. If breathing is affected or a dermal rash develops, immediately cease using this product and seek medical attention. Read SDS before using.
TASK™ 6
TASK™ 6 low cost, high performance casting resin yields castings that are tan and virtually bubble free. This resin offers superior physical and performance properties compared to our popular Smooth-Cast™ Series of general purpose casting resins. Vacuum degassing is not necessary and it offers the convenience of a 1A:1B by volume or weight mix ratio.
TASK™ 6 has high tensile and flexural strength, as well as high flexural modulus. This plastic was formulated for a variety of industrial applications including pattern making and making prototype models. This resin is designed for casting in thicknesses up to ½” (1.27 cm).
