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.

PMC 780 1-Gallon Kit – 10.89kg Instructions

PMC 780 1-Gallon Kit – 10.89kg Preparation

This product has a limited shelf life and should be used as soon as possible. Materials should be stored and used at room temperature (73°F/23°C). Humidity should be low. 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™ is a fast drying sealer suitable for sealing porous surfaces without interfering with surface detail. You can also use Sonite™ Wax. A high quality Shellac is suitable for sealing modeling clays that contain sulfur or moisture (water based).

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 like Ease Release™ 2910 (aerosol) or Ease Release 2910 (liquid)  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 the release agent 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 drastically reduced after opening. Immediately replacing the lids on containers after dispensing product will prolong the shelf life of the unused product. 

PMC 780 1-Gallon Kit – 10.89kg Measuring & Mixing

Liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal or plastic.

IMPORTANT: Pre Mix the Part B before using. After dispensing the required amounts of Parts A and B into mixing container, mix thoroughly for at least 3 minutes making sure that you scrape the sides and bottom of the mixing container several times.

If Mixing Large Quantities (24 lbs./11 kgs. or more) at one time, we suggest using a mechanical mixer (i.e. Squirrel Mixer or equal) for 3 minutes followed by careful hand mixing for one minute as directed above. Then, pour entire quantity into a new, clean mixing container and do it all over again.

Although this product is formulated to minimize air bubbles in the cured rubber, vacuum degassing will further reduce entrapped air. A pressure casting technique using a pressure chamber can yield totally bubble free castings. Contact AMT Composites for further information about vacuum degassing or pressure casting.

PMC 780 1-Gallon Kit – 10.89kg Pouring

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.

Curing

Allow the mold to cure (at least 48 hours) at room temperature (73°F/23°C) before demolding. Do not cure rubber in temperatures less than 65°F/18°C. Cure time can be reduced with mild heat or by adding Kick-It™ Cure Accelerator.

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.

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.

PMC 780 1-Gallon Kit – 10.89kg Performance & Storage

Fully cured rubber is tough, durable and will perform if properly used and stored. The physical life of the rubber depends on how you use it. Contact Smooth-On directly with questions about this material relative to your application.
