Product Description
Mold Max™ 29NV
Mold Max™ 29NV is a Shore 29A tin-catalyzed silicone mold rubber that offers low viscosity, fast cure and long library life.
Mold Max™ 29NV does not require vacuum degassing. Mix ratio is 100A:10B by weight. Working time is 45 minutes and cure time is 6 hours at room temperature.
Mold Max™ 29NV will reproduce the finest detail and is suitable for a variety of industrial and art related applications including making molds for reproducing prototypes, furniture, sculpture and architectural elements. Cure time can be reduced with Accel-T™ cure accelerator. Mold Max™ 29NV can be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins. Important: Do not cast concrete into rubber molds made with this product. Concrete will not cure properly and inhibition will result.
Important; you must weigh Part A & B components using a gram scale to be successful with Mold Max™ 29NV.
Clear Flex™ 30
Clear Flex™ 30 is a mercury-free and phthalate-free water white clear urethane liquid rubber compound designed for applications that require absolute clarity and resistance to sunlight. Low viscosity ensures easy mixing and pouring. Clear Flex™ 30 cures at room temperature with negligible shrinkage. Cured castings are clear, flexible and UV Resistant. Vibrant colors and color effects are achieved by adding pigments. Applications include making model reproductions, decorative cast pieces, special effects, prototype parts.
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.
