Worbla's KobraCast Art

Worbla’s® KobraCast Art (WKA) – the most versatile Worbla’s® ever!

Worbla’s® KobraCast Art: You can simply call it the Jack of all trades from Cast4Art and just like all the products of the Worbla’s® Art Series it is solvent-free produced and to proceed and contains no hazardous substances.

It is activated by heat (best approx. 80-90 °C / 175-195 °F) and can be shaped easily by hand or even thermoformed. WKA can be re-activated as often as you like and all leftovers can be re-used so there is almost no waste.

Worbla’s® KobraCast Art contains strong heat activated glue which means it sticks very well to itself and to other materials if treated properly.

What makes Worbla’s® KobraCast Art so unique is the very stretchable, but tear-resistant mesh inside. This makes it possible to cast organic shapes (e.g. antlers). WKA stays a little flexible even after cooling down hence it is no problem separating it even from negative moulds including undercuts.

Worbla’s® KobraCast Art’s surface provides for example good adherence for glass colors & spray paint.

What’s new is that you can sew through it quite easily for attaching (faux)-leather & -furs, fabrics and more. Because the WKA is pretty light-weighted too, it is ideal for a stabilizing substructure to use for bags, corsets and much more!
