Worbla‘ s® KobraCast Art (WKA) - the most versatile Worbla’s® ever! Just like all the products of the Worbla’s® Art Series it is solvent -free produced and to proceed and contains no hazardous substances. The WKA is activated by heat (best approx.
80-90 °C / 175-195 °F) and can be shaped easily by hand or even thermoformed. The material 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 it self and to other materials if treated properly. What makes WKA so unique is the very stretchable, but tear-resistant mesh inside.
This special mesh makes it possible to cast organic shapes (e.g. antlers) with the Worbl a’s® KobraCast Art. The material 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 e.g. fabrics, (faux)-leather & -furs and more. Because the WKA is pretty light-weighted too, it is ideal for a stabilizing substructure to use for bags, quivers, corsets and more.
