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).

Brush-On 40 1-Gallon Kit – 8.17kg Instructions

Preparation

Materials should be stored and used in at room (73°F/23°C). Humidity should be low. These products have a limited shelf life and should be used as soon as possible. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Good ventilation (room size) is necessary.

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. SuperSeal™ are fast drying sealers suitable for sealing porous surfaces without interfering with surface detail. Shellac is suitable for rough contours. A high quality spray shellac is suitable for sealing modeling clays that contain sulfur or moisture (water based). Thermoplastics (polystyrene) must also be sealed with shellac or PVA.

In all cases, the sealing agent should be applied and allowed to completely dry prior to applying a release agent.

Non-Porous Surfaces

Metal, glass, hard plastics, sulfur free clays, etc. require only a release agent.

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 (Universal™ Mold Release available from AMT Composites in 1kg Universal Mold Release and 0.18kg Universal Mold Release). 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. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

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

Measuring and Mixing

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

Mixing

Part B is a paste with the consistency of cake frosting. Fill a container to the top with this paste, making sure to eliminate any large voids. Level off the top of the container and remove any excess material. The paste should then be thoroughly emptied into a larger container that will act as your mixing container. Next, fill the original container to the top with Part A (liquid) and empty it into the mixing container. After dispensing equal amounts of Parts A and B into mixing container, mix thoroughly for 3 minutes making sure that you scrape the sides and bottom of the mixing container several times.

Applying The Rubber

This product must be applied in layers. Mold makers generally find that four to six layers (minimum 3/8”) thickness is suitable for a working mold. Using a stiff brush, the first coat of rubber should be applied in a thin layer to capture intricate detail. Use dabbing strokes, especially around undercuts, to reduce entrapped air. Subsequent coats will add strength to the mold. Let the first coat dry for 30-40 minutes at room temperature or when it becomes “tacky” before adding the next coat. Repeat until the necessary thickness is achieved. Do not allow rubber to fully cure between layers, as delamination may result. Note: Although not necessary, adding a small amount of SO-Strong™ liquid color pigment to every other mix of rubber will help you distinguish one layer from the next. This will ensure that you apply a thorough coating each time and help build uniform layers.

Curing

Allow rubber to cure overnight (at least 16 hours) at room temperature (73°F/23°C) before demolding. Cure time can be reduced with mild heat or by adding Smooth-On “Kick-It™” Cure Accelerator. Do not cure rubber where temperature is less than 65°F/18°C.

Post Curing

After rubber has cured at room temperature, heating the rubber to 150°F (65°C) for 4 to 8 hours will increase physical properties and performance.

Apply A Support Shell

Once the mold is fully cured, a rigid support shell (mother mold) is needed to support the rubber mold during casting.

Using The Mold

If using as a mold material, a release agent should be applied to the mold before each casting. The type of release agent to use depends on the material being cast. The proper release agent for wax, liquid rubber or thermosetting materials is a spray release made specifically for mold making. Prior to casting gypsum plaster materials, sponge the mold with a soap solution for better plaster flow and easy release.

Performance & Storage

Fully cured molds are tough, durable and will perform if properly used and stored. The physical life of the mold depends on how you use it (materials cast, frequency, etc.). 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. Do not stack molds, expose them to moisture or UV light.
