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).

Please check the box to acknowledge our return’s policy, by doing so you agree to our Return’s Policy of AMT Composites stated above.

Features of Mold Max™ 10 Standard – 5.5kg

  • Mold Max™ 10 Standard will reproduce the finest detail and are suitable for a variety of industrial and art related applications including making molds for reproducing prototypes, furniture, sculpture and architectural elements.
  • Mold Max™ 10 Standard can be thickened with THI-VEX™ additive for brush-on applications.
  • Mold Max™ 10 Standard can be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins (without using a release agent).

Instructions – Mold Max™ 10 Standard – 5.5kg

Important – you must weigh Part A & B components using a gram scale to be successful with Mold Max™ silicones.
Safety – Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Wear vinyl gloves only. Latex gloves will inhibit the cure of the rubber.

Store and use material at room temperature (73°F/23°C). Storing material at warmer temperatures will also reduce the usable shelf life of unused material. These products have a limited shelf life and should be used as soon as possible.

Applying a Sealer/Release Agent

Mold Max™ rubber may be inhibited by sulfur based clays resulting in tackiness at the pattern interface or a total lack of cure throughout the mold. If compatibility between the rubber and the surface is a concern, a small-scale test is recommended. Apply a small amount of rubber onto a non-critical area of the pattern. Inhibition has occurred if the rubber is gummy or uncured after the recommended cure time has passed. To prevent inhibition, a “barrier coat” of clear acrylic lacquer sprayed directly onto the pattern is usually effective. Allow to thoroughly dry. Although not usually necessary, a release agent will make demolding easier when casting into or over most surfaces. Ease Release™ 200 is a proven release agent for making molds with silicone rubber and for releasing new silicone from cured silicone. Mann Ease Release™ products are available AMT Composites here.

Measuring & mixing

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. After mixing parts A and B, vacuum degassing is recommended to eliminate any entrapped air in liquid rubber. 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/Curing/Post Curing

For best results, pour your mixture in a single spot at the lowest point of the containment field. Let the rubber seek its level up and over the model. A uniform flow will help minimize entrapped air. The liquid rubber should level off at least 1/2” (1.3 cm) over the highest point of the model surface. Allow the mold to cure overnight (at least 16 hours) at room temperature (73°F/23°C) before demolding. Post curing the mold an additional 4 hours at 150°F (65°C) will eliminate any residual moisture and alcohol that is a byproduct of the condensation reaction that can inhibit the cure of some urethane resins and rubbers. Allow mold to cool to room temperature before using. Do not cure rubber where temperature is less than 65°F/18°C.

Thickening Mold Max™ 10 Standard Silicones For Brush-on Application

THIVEX™ is made especially for thickening Smooth-On’s Mold Max™ 10 silicone for vertical surface application (making brush-on molds). Different viscosities can be attained by varying the amount of THI-VEX™. Apply a thin coat of rubber. Wait for rubber to become “tacky” before applying next coat. Final mold thickness should be at least 3/8” (1 cm). Allow rubber to cure overnight before applying support shell. See the THI-VEX™ technical bulletin for full details.

Accelerating Mold Max™ 10 Silicones

Accel-T™ silicone rubber accelerators will accelerate the cure time of Mold Max™ 10 silicone rubber. Note: working time is reduced in proportion to the amount of FastCat™ or Accel-T™ added. Using this accelerator will result in a shorter library life of the mold.

Thinning Mold Max™ 10 Standard Silicones

Silicone Thinner™ is a non-reactive silicone fluid that will lower the mixed viscosity of tin cure (condensation) or platinum cure (addition) silicone rubber products. Silicone Thinner™ offers the following advantages: [1] A lower mixed viscosity (A+B) means that the rubber will de-air faster when vacuuming; [2] Mixed rubber (A+B) will flow better over intricate model detail; [3] Silicone Thinner™ will lower the ultimate shore hardness (durometer) of cured silicone rubber; [4] Pot life (working time) is increased in proportion to the amount of Silicone Thinner™ used. A disadvantage is that ultimate tear and tensile are reduced in proportion to the amount of Silicone Thinner™ added, however knotty tear properties of the Mold Max™ Series rubbers are unaffected. It is not recommended to exceed 10% by weight of total system (A+B). See the Silicone Thinner™ technical bulletin for full details.

Mold Performance & Storage

The physical life of the mold depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials such as concrete can quickly erode mold detail, while casting non-abrasive materials (wax) will not affect mold detail. Before storing, the mold should be cleaned with a soap solution and wiped fully dry. Two part (or more) molds should be assembled. Molds should be stored on a level surface in a cool, dry environment.
