Model Making Materials

Mould making Vytaflex 20A 0.9kg.

For perfect concrete castings - Shore 20A hardness.

Using Smooth-On's exclusive "V-Polymer" technology, VytaFlex® urethane rubbers offer superior physical and performance properties.

VytaFlex® urethanes feature convenient one-to-one by volume mix ratios.

Vacuum degassing is not necessary and VytaFlex® rubbers cure with negligible shrinkage to a durable rubber that will last in production.VytaFlex® mould rubbers are used for a variety of applications including making moulds to reproduce sculpture and architectural elements, as well as for making special effects, toys and prototypes.

Vibrant colours can be achieved by adding colour tints.

We used Vytaflex (30A) mixed with black polyurethane pigment (CR20052) to make the tyres for a RC racing car.

If the cast need to be water clear, use Encapso K.

VytaFlex® mould rubbers work especially well for casting pigmented / coloured concrete.

Moulds made with VytaFlex® Series urethanes will render accurate and uniform coloured castings.

Use IPA Isopropyl to clean up any uncured material.
