Smooth-Cast® ONYX™ 8.4kg is a mercury-free urethane resin that cures at room temperature to a deep black, solid plastic. ONYX™ resins offer the convenience of a 1A:1B by volume mix ratio and have very low viscosities, so they are easy to mix and pour.

  • ONYX™ resins have an ultimate Shore hardness of 80D and offer higher physical properties and higher heat resistance vs. other general purpose resins.
  • ONYX™ FAST resin has a pot life of 2.5 minutes and a cure time of 10-15 minutes.
  • ONYX™ FAST is a good choice for creating fast cold cast bronze, brass, copper, nickel/silver, etc. effects.

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.

Processing Recommendations

Preparation

  • These products have a limited shelf life and should be used as soon as possible.
  • Materials should be stored and used in a warm environment (73°F/23°C).
  • All liquid urethanes will react with moisture in the air, causing bubbles.
  • Use in a low humidity environment (below 50% RH).
  • Mixing containers should have straight sides and a flat bottom.
  • Mixing sticks should be flat and stiff with defined edges for scraping the sides and bottom of your mixing container.

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.

Applying A Release Agent

A release agent is necessary to facilitate demolding when applying into or over most surfaces. Use Mann’s Ease Release™ 200 which will release both urethanes and silicones. A liberal coat of release agent should be applied onto all surfaces that will contact the plastic.

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

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

Mixing and Pouring

Mixing

Stir or shake Part A and Part B thoroughly before dispensing. After dispensing required amounts of Parts A and B into mixing container, mix thoroughly. Stir for at least 60 seconds, making sure that you scrape the sides and bottom of the mixing container several times.

Pouring

For best results, pour your mixture in a single spot at the lowest point of the containment field and let the mixture seek its level. This will help minimize air entrapment.

Curing and Performance

Curing

Important: Use this product with at least room size ventilation or in proximity to a forced outlet air vent and do not inhale/breathe fumes. Fumes, which may be visible with a significant mass concentration, will quickly dissipate with adequate ventilation.

Castings with significant mass may be hot to the touch and irritate skin immediately following cure. Let casting cool to room temperature before handling.

Demold time of the finished casting depends on mass and mold configuration. Low mass or thin-walled castings will take longer to cure than castings with higher mass concentration.

Post Curing

Although not necessary, post curing will increase physical properties, material performance and heat resistance to 250°F/121°C for ONYX™ FAST and 212°F/100°C for ONYX™ SLOW. After curing at room temperature for 1 hour, expose material in the mold to 250°F/121°C for 4–6 hours. Let cool to room temperature before use.

Performance

  • Cured castings are hard and durable.
  • They resist moisture, moderate heat, solvents, dilute acids and can be machined, primed and painted or bonded to other surfaces (any release agent must be removed).
  • If machining castings, wear dust mask or other apparatus to prevent inhalation of residual particles.
  • Castings can be displayed outdoors after priming and painting.
  • Unpainted castings may be affected by UV light.

Because no two applications are the same, a small test application to determine suitability is recommended if performance of this material is in question.
