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.

AMPRO™ Colloidal Silica is an agent which is used to control the thixotropy or ‘sag’ characteristics of a resin system.

By adding colloidal silica powder in varying amounts to a resin mix containing the other filler types mentioned, the handling and
flow characteristics can be controlled.

Relatively small quantities added to a resin mix containing glass bubbles or microballoons will give non-sag properties and impart easier handling. Colloidal silica is also used with microfibres to produce a mix suitable for use as a high strength, non-sagging structural adhesive, particularly for non-absorbent materials such as grp. The inclusion of colloidal silica has the effect of increasing the hardness of the resulting mix which will create more difficulty when sanding. For this reason colloidal silica is usually added in the minimum quantities to any mix for which sanding is anticipated. In some applications this feature can be used to an advantage, for example to create a hard wearing edge or surface.

AMPRO™ Silica is naturally water-resistant / hydrophobic making it more suited for marine applications. Lower loading levels are required compared to traditional silica, up to 2% reduction by weight.

Hollow spheres

Increase the volume and reduce the density of any resin system and are used to make adhesive mixes and filling & fairing mixes.

  • Microballoons: Brown microsphere filler powder used to make glues or paste fillers
  • Glass Bubbles: White microsphere filler powder used to make glues or paste fillers

Short Fibres

For adding strength to a resin and hardener mix used as a structural adhesive, short reinforcing fibres are often added which act in a
similar strengthening way to the long reinforcing fibres used in composite construction.

  • Microfibres: Cellulose fibres used to make adhesive mixes

Flow Modifiers

The most common material for modifying the flow properties of a resin mix is colloidal silica. This is a very fine powder which is added
in conjunction with other fillers to ‘thicken’ mixes and reduce their flow on vertical surfaces (increase thixotropy).

  • Colloidal Silica: Fine, anti-sag, filler powder. Use in combination with other filler powders
