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.

If a product is backordered and ordered with other products, your order will only ship once the backordered item is back in stock.

RE33 & HE33 CLF – 1.103kg Processing

  • Thorough mixing of the components is essential before dispensing into the mould.
  • To obtain the correct pot life and Shore hardness the product is typically cast with both components at 25°C into a mould at ambient temperatures (20 – 25°C).

Pot life and demould time will decrease as:

  • Resin/mould temperatures are increased (70-90◦C) and,
  • The mass of the total casting is increased.

Winter conditions

The Part B may form crystals when stored at low ambient temperatures (below 15 – 20°C). In this case, the product must be heated to 60 – 70°C for the crystals to melt and then cooled down to 25°C before use. When Part B has been melted, it should be used as soon as possible. Do not heat Part B in excess of 70°C or store at 60° – 70°C for prolonged periods of time.

Storage and stability

RE33 Polyol is hygroscopic and must be stored in well-sealed containers at ambient temperatures of between 20-25◦C, away from direct sunlight. Containers must be sealed after use.
HE33 (CLF) is a diisocyanate and will react with moisture generating carbon dioxide. HE33 (CLF) has a shelf life of 6 months. Containers must therefore be tightly resealed after use to minimize moisture absorption. Using a “Gas-Blanket” is recommended.

Safety & Handling

RE33/HE33 (CLF) must be handled with care. Keep away from foodstuffs and handle with appropriate protective clothing.
Inhalation of fumes must be strictly avoided, and protective mask should be worn in a well-ventilated area. The safety procedures applicable to handling urethane raw materials must be read, understood and strictly adhered to.
