Clear Flex™ 30 EU /1 kg

Clear Flex™ 30 EU

Clear Flex™ 30 EU 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.

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.

Hardness: Shore A30 - Mix Ratio by Weight: 100A : 94B - Mix Ratio by Volume: 1A : 1B cure time 16h
Cured castings are: Clear - Flexible - UV Resistant

Vibrant colors and color effects are achieved by adding pigments. Applications include making model reproductions, decorative cast pieces, special effects, prototype parts.

These products are new EU versions, specially formulated to comply with European regulation.

Instructions

PREPARATION - Store and use at room temperature (73°F / 23°C). These products have a limited shelf life and should be used as soon as possible. Liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Environmental humidity should be as low as possible. Mixing tools should be made of metal or plastic.

Apply Sealing and Release Agents - Clear Flex™ is adhesive and will bond to many surfaces. If pouring Clear Flex™ into a porous mold (such as plaster), seal the surface with SuperSeal™. Follow sealer coat with Universal Mold Release™. If pouring Clear Flex™ into a urethane mold, apply Universal Mold Release™ before casting. Use as directed. If unsure about surface compatibility, a small scale test casting should be made.

Selecting A Mold Rubber - Clear Flex™ 30 will cure in 16 hours at 73°F / 23°C. Surface may remain sticky or tacky for some time depending on which mold rubber is used to cast Clear Flex™ into. The tacky surface on newly demolded castings can be eliminated by post curing the casting out of the mold at 150°F / 60°C for 5 hours. Clear Flex™ 30 can be poured into a mold made using Mold Max™ 10, 14NV, 20, 25, 30 or 40 or Mold Star™ silicone. Clear Flex™ 30 will not work in a Mold Max™ 10T, 15T or 20T silicone mold

If Using Mold Max™ Silicone - to prevent cure inhibition, post cure newly made silicone mold for 4 hours at 60°C and let cool prior to casting Clear Flex™.

The tacky surface on newly demolded castings can be eliminated by post curing the casting out of the mold at 60°C for 5 hours.

IMPORTANT: Shelf life of product is reduced after opening. Remaining product should be used as soon as possible. Immediately replacing the lids on both containers after dispensing product will help prolong the shelf life of the unused product. XTEND-IT™ Dry Gas Blanket Available from Form X will significantly prolong the shelf life of unused liquid urethane products

Pre Mix the Part B before using. After dispensing proper amounts of Parts A and B into mixing container, mix thoroughly for at least 3 minutes making sure that you scrape the sides and bottom of the mixing container several times.

If Mixing Large Quantities - 7 kg. or more at one time, use a mechanical mixer (i.e. turbine mixer or equal) for 3 minutes followed by careful hand mixing for one minute as directed above. Then, pour entire quantity into a new, clean mixing container and do it all over again. If coloring or filling Clear Flex™, add filler or pigment dispersion to Part B and mix thoroughly before adding Part A.

Important: Material is mass sensitive and will exotherm. Large amounts of material cast at one time will generate mild heat and will shrink in proportion to mass. The more material cast in a large concentration, the higher the shrinkage. Amount and nature of shrinkage will depend on casting thickness and mold configuration.

VACUUMING MATERIAL - If vacuum degassing prior to pouring, subject mixture to 0,98 bar of mercury in a suitable vacuum chamber for 2 -3 minutes or until mixture rises, breaks and falls. Allow for 3 to 4 times volume expansion in mixing container.

Pouring - If casting Clear Flex™ into a rubber mold, pour mixture in a single spot at the lowest point of the mold. If encapsulating an object, do not pour the mixture directly over the object. Let the mixture seek its level. A uniform flow will help minimize entrapped air.

For Best Results - Best results are obtained using a pressure casting technique. After pouring the mixed compound, the entire casting assembly (mold, dam structure, etc.) is placed in a pressure chamber and subjected to 60 PSI (4.2 kg / cm2 ) air pressure for at least two hours. For most applications, room temperature curing 23°C for 24–48 hours is adequate. Castings will reach ultimate physical properties at room temperature in 5–7 days.
