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.

Features

Cured castings are:

  • Clear
  • Flexible
  • UV Resistant.

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

Changing your Mind / Right to Cancel

If you change your mind for any reason, goods can be returned to us for a full refund if notified to us within 7 days of delivery; you have a further 7 days to dispatch the goods for their return to us. Goods returned after 7 days will incur a 15% restocking fee of the items being returned.

NO GOODS manufactured or sold by Advanced Materials Technology Pty Ltd will be accepted for a credit if returned after one (1) calendar month of original invoice date.

To return goods that are not faulty (i.e. because you changed your mind) they must be unused and, in the condition, they were delivered to you in. This does mean that, unless found faulty, we are unable to accept returns for:

  • Opened containers of resin, hardener, silicone or chemical release agent, unless found to be faulty or defective.
  • Unrolled and improperly re-rolled fabrics, unless found to be faulty or defective.
  • Any product that you have subsequently cut, shaped, broken or modified, unless found to be faulty or defective.

Refund of Delivery Charges (Cancelled Orders)

If you return an order in its entirety, then your outbound delivery charges will also be refunded (for orders within the South Africa’s Local Area’s.

If you return only part of an order, then the outbound delivery charge refund will be calculated based on the total postage cost of the original order (using standard service) minus the cost to send the items you are keeping (using standard service). Due to the way that shipping costs are incremented, this will often result in no delivery charge refund being due.

Faulty or Defective Goods

Any goods found to be faulty or defective and notified to us within 7 days of delivery can be returned to us for a full refund.

Refund of Delivery Charges (Faulty/Defective Goods)

If you are returning faulty or defective goods, then your outbound and return delivery costs will be refunded in full (for orders from within South Africa’s Local Area’s.)

In the event that you are returning faulty or defective goods which were ordered as part of a larger order then the outbound delivery charge refund will be calculated based on the total postage cost of the original order (using standard service) minus the cost to send the items you are keeping (using standard service).

Clear Flex 50 Instructions

Safety

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. Environmental humidity should be as low as possible. Good room size ventilation is essential. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Wearing a NIOSH approved respirator will minimize inhalation of residual fumes.

Some Materials Must Be Sealed

To prevent adhesion between the rubber and model surface, models made of porous materials (gypsum plasters, concrete, wood, stone, etc.) must be sealed prior to applying a release agent. The best sealer for sealing porous materials is SuperSeal™ 1kg or SuperSeal™ 0.18kg (Available from AMT Composites). Spray shellac is suitable for rough contours. A high quality Shellac is suitable for sealing modeling clays that contain sulfur or moisture (water based). Allow sealer to dry thoroughly.

Applying A Release Agent

A release agent is necessary to facilitate demolding when casting into or over most surfaces. Use a release agent made specifically for mold making. A liberal coat of release agent should be applied onto all surfaces that will contact the rubber.

IMPORTANT: To ensure thorough coverage, lightly brush the release agent with a soft brush over all surfaces of the model. Follow with a light mist coating and let dry for 30 minutes.

Selecting A Mold Rubber

Pour into a urethane rubber mold (Vytaflex™ urethane (VytaFlex™ 30 – 1kg, VytaFlex™ 30 – 2kg, VytaFlex™ 60 – 1kg, VytaFlex™ 60 – 2kg) – release agent required tin cured silicone mold (Mold Max™ 10, 14NV, 20, 25, 30 or 40 silicone) or Mold Star™ 15, 16 or 30 platinum cured silicone mold. Clear Flex™ 50 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 silicone mold for 8 hours at 60° C / 150° F and let cool prior to casting resin. If you are unsure about surface compatibility, a small scale trial casting should be made.

For Best Results Before Pouring Clear Flex Into Mold

Pre-heat rubber mold at 212°F / 100°C for 4 hours. This will minimize chances of fish-eyeing, suck back, corner rounding, large bubbles, etc. in finished casting.

Liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal or plastic. Materials should be stored and used in a warm environment (73°F/23°C).

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 AMT Composites) will significantly prolong the shelf life of unused liquid urethane products.

Pre Mix the Part B before using

Before you begin, pre-mix Part B thoroughly to re-disperse pigments that may have settled. Using a gram scale, dispense required amounts of parts A and B into a mixing container and mix for 3 minutes. Scrape the sides and bottom of the container several times.

If Mixing Large Quantities

(16 lbs./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 50, 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 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, your vacuum pump must pull a minimum of 29 inches of mercury (or 1 Bar / 100 KPa). Leave enough room in container for material expansion. Vacuum material until it rises, breaks and falls. Vacuum for 1 minute after material falls.

Pouring

If casting Clear Flex 50 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.

Post Curing

Castings will cure faster and achieve maximum physical properties and heat resistance if Clear Flex 50 is post cured. Post curing is recommended if castings are thin or low mass concentration. Castings should be post cured in a mold or support structure.

Post Cure Schedule

Allow the material to cure for 6–8 hours at room temperature followed by 16 hours at 150°–160°F (65°–72°C). Allow casting or part to cool to room temperature before demolding.

For most applications, room temperature curing (73°F/23°C) for 24–48 hours is adequate. Castings will reach ultimate physical properties at room temperature in 5–7 days. Castings removed from mold before 12 hours may exhibit a tacky surface that can be eliminated by exposing casting to 150°F/65°C for 4–6 hours. If you are pouring less than 1/4 in. / 0.64 cm of material, the casting should be heat post cured.
