Rigid Urethanes
Rigid Unfilled Urethanes 
These rigid casting systems range in hardness from 65 Shore D to 85 Shore D and have been designed to meet a wide variety of applications. These are all rigid materials when set, however other characteristics vary and should be considered when selecting a product to meet your requirements.
Technical details to examine include :
- how brittle is it
- how far will it bend before breaking
- how much strength is required to break it
- is it UV stable for outdoors use
- what is the heat threshold
Most commonly they are used to cast models & miniatures, objects of art, industrial prototypes, toys, architectural shapes, ornaments, picture frames and more. These systems provide various demold times which can range from 5 minutes to overnight.
EasyCast®, Supercast® Procast®
Most popular and economic range of rigid urethanes. Most popular is EasyCast, which is mixed by equal volume, can be processed easily, and with its short demold time, parts can be produced quickly.
EasyCast is a two-component rigid urethane casting compound. It cures to Shore 73D and is white in colour. EasyCast is a rapid setting Material that demonstrates slightly more flexibility than other similar materials. This material can be solid cast, or slushcast. EasyCast is machinable, can be sanded, drilled, turned and ground. EasyCast accepts a wide range of fillers and can reproduce the most minute detail as a result of its extremely low viscosity. This system is easily pigmented and fast turnover of parts can be achieved.

Supercast and Procast are mixed in equal quantities by Weight. These urethanes have slightly different characteristics, but all are rigid &fast setting.

4PU
Want more working time, but still have fast demold??
4PU is a low viscosity, rapid setting, 100% solids rigid urethane compound. This system is easy to process and has a low exotherm of 76șC maximum. 4PU will cure quickly to a hard, tough casting. 4PU is generally insensitive to moisture during and after curing and is suitable for use with most general purpose dry fillers.
Ideal for -
- Ornamental Mouldings
- Prototypes
- Models
- Picture Frames
- Decorative Components

Rigid Filled Urethanes
We currently stock only one Rigid Filled Urethane, called Ultracast or TC1630. This product is generally used for making molds and foundry patterns, however, it is often used to make parts as well. It is thicker in viscosity than unfilled systems, so needs to be processed quickly, preferably with drill mixer, to ensure even dispersement prior to pouring into prepared container. Also great for making accurate and durable molds for casting Gelatine. Grey in colour.
Size: only available in 9.07kg (1 gal) kits.
| Product Name | Shore Hardness | Work Time (Min) | Demould Time (Hrs) |

Trowel-On 60
Thixotropic Rigid Polyurethane
TROWEL-ON 60 is a two component brush-on polyurethane that is capable of vertical hand lay-ups. It is a great substitute for creating non-fibreglass case moulds / mother moulds.
TROWEL-ON 60 can also be used for creating thin walled, lightweight and hollow shell parts. It can be used as a filleting material and is ideal for coating polystyrene foam. TROWEL-ON 60 has an easy 1:1 mix ratio and can be demoulded in 1-2 hours. Finished parts are extremely hard and durable.
Typical Applications:
- Architectural element
- Case moulds / mother moulds
- Thin walled parts and panels
- Theatrical and SFX components
- Casting lightweight parts
- Polystyrene foam coating system
Size: 500gm, 1kg
